Nano-hybrid plasmonic photocatalyst for hydrogen production at 20% efficiency

Abstract The efficient conversion of light energy into chemical energy is key for sustainable human development. Several photocatalytic systems based on photovoltaic electrolysis have been used to produce hydrogen via water reduction. However, in such devices, light harvesting and proton reduction a...
