Abstract:
Multifunctional nanostructures find the possibility for their applications in water splitting processes for hydrogen generation as a renewable source of green energy. Photocatalytic generation of hydrogen in water splitting process by using as-prepared nanoparticles has also been studied under the visible light irradiations which showed a significant H2 evolution reaction rate. Fe3O4 nanocubes were prepared in one pot process for the electrochemical water splitting and supercapacitor applications. As-synthesized Fe3O4 nanocubes with high specific surface area of 268 m2g-1, are ferromagnetic at room temperature and affects the electro-catalytic activity of the electrode materials. Similarly, the catalytic activity of ultrafine RuO2 was examined against the Horseradish peroxidase enzyme (HRP) and applied as sensor for the detection of H2O2 in the solution. Besides that, the stimulating bifunctional electro-catalytic performance of RuO2 nanoparticles was studied under different atmospheric conditions for electrochemical hydrogen energy. The studies of Yttrium Ferrite nanoparticles by citrate precursor route reveal the formation of monophasic orthorhombic YFeO3 nanoparticles with fairly uniform distribution of nearly spherical particles, high specific surface area of ~338 m2/g and visible band gap of 2.5 eV. Photocatalytic generation of hydrogen by using YFeO3 nanoparticles has also been studied under the visible light irradiations which showed a significant H2 evolution reaction rate up to 131.6 µmol h-1g-1. Some more studies on renewable energy will also be discussed.
