Abstract
Semiconductor nanocrystals (NCs) are the building blocks for the future opto-electronic devices, and other energy-harvesting applications. Although the energy demand has been increasing, energy sources are diminishing. Hydrogen, green energy source, is used in space shuttles and other transportation means. The hydrogen production using semiconductors such as TiO2 suffers from several limitations, and hence, alterative techniques for hydrogen production are desired. Recently, photocatalysis using different nanostructures has been studied.1-6 In this project, we have studied the catalytic activity of gold/cadmium sulphide (Au/CdS) NCs to reduce protons into hydrogen qualitatively. The Au/CdS NCs absorb a large amount of visible photons due to plasmon resonance and create electron-hole pairs. The excited electrons migrate to the catalysts, and the protons are reduced while the ligands on the surface of NCs scavenge holes. Thus, photocatalysis occurs due to the energy transfer from metal to semiconductor materials. The hydrogen production using Au/CdS metal semiconductor NCs is more efficient than that of using CdS semiconductor NCs.
