Chemical Engineering Journal, 2026
Heavy-metal-free quantum dots (QDs) based photoelectrochemical (PEC) water splitting has emerged as a promising approach for green hydrogen (H 2 ) production. However, a high density of surface defects/traps substantially limits efficient carrier dynamics and, consequently, overall device performance. In this work, we engineered Cu-Zn-In-Se (Cu-ZISe) QD surfaces by optimizing the alloyed ZnSeS (ZSeS) shell via aluminum (Al) doping to enhance optoelectronic properties and PEC H 2 production performance. The strategic growth of an alloyed ZSeS shell layer effectively passivates surface trap/defect states, promoting a favorable band alignment for efficient carrier dynamics. The incorporation of Al into the alloyed shell layer modulates the electronic band structure and induces the formation of a thin Al-oxide layer, thereby enhancing carrier separation, improving interfacial stability, and enhancing the efficiency of PEC devices. The optimized Cu-ZISe/ZSeS:Al core/alloyed shell QDs-based PEC with polysulfide electrolyte of 0.25 M Na 2 S and 0.35 M Na 2 SO 4 (pH = 14) exhibits a high photocurrent density of 13.91 mA/cm 2 at 1 V under one-sun illumination (AM 1.5G, 100 mW.cm −2 ), which is 65% superior compared to the core Cu-ZISe QDs-based PEC device (8.40 mA/cm 2 at 1 V). Importantly, the PEC device retained 87% and 36% of its initial performance after 2 h and 10 h continuous operation, respectively, under one-sun illumination. This work provides critical insights into alloyed-shell and dopant-assisted engineering strategies for advancing heavy-metal-free QDs-PEC systems toward practical green H 2 production and other QDs-based optoelectronic devices. • Al-ZnSeS alloyed shell passivates core QD surface traps and enhances stability. • Alloyed-shell Al-ZnSeS engineering improves interface quality and carrier dynamics. • PEC device with alloyed-shell QDs yield 65% higher performance than the control QDs. • Stable PEC device with 87% photocurrent retained after 7000 s continuous operation.

Carbon, 2026
Quantum dots (QDs) are tiny-sized nanoparticles that offer distinct optical and electronic properties tunable with size/shape/composition, resulting from the quantum confinement effect. However, high-performing heavy-metal-based QDs (e.g., CdS, PbS) exhibit toxicity, raising concerns for large-scale applications. Carbon quantum dots (CQDs) and graphene quantum dots (GQDs) offer a safer alternative and possess remarkable properties, including biocompatibility, solution processability, and photostability. In recent years, carbon-rich agricultural and marine waste streams have been explored as effective precursors for synthesizing CQDs and GQDs. Additionally, these sources offer a promising alternative to traditional methods, making the synthesis process more environmentally friendly and cost-effective and promoting the circular economy. This review focuses on CQDs and GQDs derived solely from agricultural and marine waste, using different innovative top-down and bottom-up approaches, emphasizing their potential for scalability and environmental benefits. It provides a comprehensive review of the structural, morphological, optical, and fluorescence properties of CQDs and GQDs synthesized from agricultural and marine waste, emphasizing novel techniques for tuning their emission characteristics. A critical evaluation of the environmental, ecological, and toxicity aspects of CQDs and GQDs is presented. Lastly, the review highlights the applications of these CQDs and GQDs in clean energy technologies such as photovoltaic, green hydrogen production, and supercapacitors. The review concludes by outlining current limitations and future research opportunities for CQDs and GQDs derived from agricultural and marine waste, emphasizing their potential in cost-effective clean energy technologies and their role in promoting a circular economy by converting waste into value-added technologies. Carbon dots derived from agricultural and marine waste and their applications in supercapacitors, photovoltaics, and green hydrogen production via photo/electrocatalytic water splitting.

Hybrid TiN - MXene Photoanodes Drive Efficient Photoelectrochemical Water Splitting
Parul Bansal, Gurpreet Singh Selopal, Kokilavani Shanmugasundaram, Hadis Zarrin, Federico Rosei
Solar Rrl, 2026
We developed quantum dot (QD)‐sensitized hybrid TiO 2 nanocomposite photoanodes consisting of titanium‐based MXene (Ti 3 C 2 T x ) and titanium nitride (TiN) to promote synergy between the transport efficiency of MXenes and the plasmonic properties of TiN nanoparticles (NPs), toward enhancing the performance of photoelectrochemical (PEC) water splitting. MXenes sheets were synthesized at room temperature through delamination of an aluminum layer of the MAX phase of titanium aluminum carbide (Ti 3 AlC 2 ), and subsequently, nano‐sized dot‐like TiN NPs were incorporated through sonication and hydrothermal reaction. The PEC system based on the optimized TiO 2 ‐MXene‐TiN (MXene:TiN 1:4 wt%) hybrid network sensitized with CdS/CdSe/ZnS QDs yields a high photocurrent density of 15.80 mA cm −2 (at 1.0 V vs. the reversible hydrogen electrode [RHE]) under 1 sun illumination (AM 1.5G, 100 mW cm −2 ), which is almost double (~119%) as compared to the control TiO 2 /QDs device (7.20 mA cm −2 ). This significant enhancement in current density is attributed to the plasmonic effect of TiN NPs, improved charge carrier mobility and reduced recombination losses arising from the incorporated MXene sheets. This improvement in charge transport directly contributes to higher device efficiency, as demonstrated by faster transient voltage decay rates and prolonged carrier lifetimes in our measurements.

Pawan Kumar, Lei Jin, Gurpreet Singh Selopal, Omar Abdelkarim, Jiabin Liu, David Barba, Aycan Yurtsever, Zhiming M. Wang, Federico Rosei
Nano Materials Science, 2026
We describe the design and synthesis of eco-friendly AgInS 2 /ZnS QDs via a facile one-pot synthesis method for application in encryption and anti-counterfeiting. A significant enhancement in PLQY (up to 45 %) and stability are observed with increased ZnS shell thickness. By varying the Ag:In composition from 1:2 to 1:0.25, the PL emission of AgInS 2 /ZnS QDs can be tuned from the visible to NIR (up to 900 nm). The ink fabricated with AgInS 2 /ZnS QDs shows greater thermal and water stability compared to AgInS 2 QDs. The patterns printed with these luminescent inks show excellent water and thermal stability and the capability to print on surfaces of any type and color, making them promising for practical use. These printed patterns are completely transparent/invisible in normal light and visible under 254 nm, 365 nm and 464 nm (blue LED) illumination. These features offer rapid responsive and multi-layered information encryption, and sophisticated anti-counterfeiting.

Energy Conversion and Management, 2025
This study explores the potential of renewable seafood shell waste for sustainable energy conversion and long-term storage, particularly for isolated communities. Despite its rich chitin and protein composition, seafood shell waste is often neglected. The research evaluates and compares three advanced gasification technologies: biomass gasification, plasma gasification, and chemical looping, to convert seafood shell waste into syngas and H 2 . The study uses validated Aspen Plus models to optimize feedstock blending ratios and operational parameters. Results show that feedstocks high in lobster and shrimp shells yield higher H 2 outputs and improved syngas quality compared to clam-dominated blends. For instance, biomass gasification at 1200 °C yielded approximately 500 kg/h of H 2 from pure lobster or shrimp feeds, while plasma gasification at 4500 °C achieved yields near 730 kg/h. Plasma gasification, when integrated with fuel cell conversion and heat recovery systems, can generate over 10,000 kWh during a 6-hour peak period, enough to power over 1100 single-detached homes. Its levelized cost of hydrogen (LCOH) varies from $5.72-$8.37/kg H 2 , making it less expensive than chemical looping and biomass gasification. Plasma gasification also has the lowest global warming potential (GWP) at 6 kg CO 2 e/kg H 2 . Combining plasma gasification with carbon capture and storage may reduce GWP to 0.3 kg CO 2 e/kg H 2 and can be further explored. These findings underscore the technical and economic viability of converting seafood shell renewable waste into H 2 , advancing sustainable energy transitions, and supporting net-zero goals.
