MXene-Based VOC Gas Sensors Anil Kulkarni, Vishal Lonikar, Pratibha Nikam, Savita Patil, Nilesh Jadhav, Babasaheb Sankapal Mxene Based Gas Sensors, 2025 Volatile organic compounds (VOCs) originate from various industrial, environmental, and biological activities are significantly posing a threat to human health and the environment. These risks can be reduced using gas sensors which are highly sensitive, selective, and efficient in detecting VOCs. Among the recent development in nanomaterials, 2D MXene materials made up of transition metal carbides, nitrides, and carbon-based hybrids have been recognized as exceptionally promising materials. Their excellent electrical conductivity, large surface area, and tunable interlayer spacing make them best suitable for gas sensing. This chapter highlights recent progress in the development of MXene-based sensors for VOC detection, surface functionalization, material design, and hybridization with polymers, metal oxide, graphene, and CNTs to enhance their sensing performance. MXenes can be incorporated into flexible and wearable sensing systems. Inclusively, MXene-based materials provide a versatile foundation for upcoming generation of VOC gas sensors with substantial potential in medical testing, environmental monitoring, and industrial automation.
Recent Advances in Graphene and TiO2-Based Materials in Dye-Sensitized Solar Cells (A Review) Lokesh D. Sonar, Sharad R. Patil, Pratibha R. Nikam Russian Journal of General Chemistry, 2025 Abstract The global energy problem and environmental issues have expedited the advancement of alternative energy technology, with solar energy becoming a significant option. Dye-sensitized solar cells (DSSCs) have attracted considerable interest owing to their economic viability, simplicity of production, and versatility. This study provides a detailed review of DSSCs, emphasizing the function of titanium dioxide (TiO2)-based photoanodes and graphene-based counter electrodes. TiO2 nanostructures, due to their high surface area, outstanding optoelectronic properties, and effective electron transport characteristics, are utilized as the main photoanode material in DSSCs. Moreover, graphene and its derivatives are examined as potential substitutes for traditional platinum in counter electrode applications, owing to their enhanced electrical conductivity, chemical stability, and catalytic efficiency for the iodide/triiodide redox couple. The discussion encompasses a range of synthesis techniques, structural modifications, and doping strategies for TiO2 and graphene-based materials, highlighting their influence on the performance of DSSCs. This study also explores the difficulties linked to these materials and possible approaches for enhancing their efficiency and durability over time. The results emphasize that enhancing the interaction among photoanodes, counter electrodes, and electrolytes is essential for progressing DSSC technology towards large-scale commercialization.
