9,10. Numerous catalysts, including TiO2, ZnO, ZnS, Al2O3, Fe2O3, and CdS, have been employed for this purpose8. ZnO material, one of the II-VI compound semiconductors, has received the most attention due to its wide
The best examples are nanotechnology uses in fields like hydrogen applications, energy production, and water purification. In fact, it is anticipated that the first significant commercial applications of nanotechnology will be in the area of renewable energy. Session-12 Ceramic and composite materials:...
Moreover, it seems that other phytochemicals, such as organic acids, are involved in the reduction of metallic ions into NPs, due to the release of hydrogen when the enol group undergoes transformation to the keto group. Thereby, organic acids act as electron donors for the reduction of ions...

Introduction The generation of electricity through renewable, sustainable means is a crucial step for meeting future anthropocentric energy demands. Several ...
[29]; therefore, at pH ≤ 5.3, ERT-B is fully protonated and therefore the selective binding to the MIPs is mainly attributed to hydrogen bonds. In more alkaline solutions, ERT-B is deprotonated, and significant charge repulsion phenomena also probably occur; therefore, the selective binding ...
Fuel cells are an enabling technology for the conversion of sustainable energy carriers (e.g., renewable hydrogen or bio-gas) into electrical power and heat. However, the hazardous raw materials and complicated experimental procedures used to produce electro-catalysts for the oxygen reduction reaction...
The degradation steps were followed by a free radical reaction, carried out using hydrogen peroxide (H2O2) and LBOE-AuNPs and inspected through a time-dependent observation of the absorbance spectrum of the reaction solution (Figure 12). The intense peak of BTB observed at an absorbance (λmax...
