Abstract

Harnessing sunlight to drive chemical reactions for energy storage is an important element in the transitiontowards green and sustainable technologies. Solar fuel production using semiconductor nanoparticles (SNPs) are widely studied but suffer from poor utilization of the solar spectrum and/or poor stability under operating conditions. A new avenue addressing these challenges involve plasmonic metal nanoparticles (PNPs). These stable materials have tunable optical properties and exciting catalytic behavior. Composite photocatalysts of SNPs and PNPs exploit the majority of the solar spectrum, provide new catalytic routes and expands the scope of solar photocatalysis. We prepare metal oxide SNPs, gold PNPs and their hybrids through mild aqueous syntheses to develop efficient photocatalyst for solar fuel production. Focus is placed on the synergetic interplay between SNPs and PNPs, understanding the complex pathways, and disentangling plasmon-driven, photothermal and heterogenous catalytic effects.
