Cover Story: This study explores the addition (via magnetron sputtering) of plasmonic Ag nanoparticles on BiVO4 to enhance reactivity in the artificial photosynthesis (AP) reaction. Nearly 80% of global energy is generated by fossil fuel combustion. AP converts CO2 and H2O into CO or hydrocarbons using solar energy, offering a more carbon-neutral approach to fuel generation. Ag interacts with photons, generating surface plasmon resonances (SPRs) which enhance catalytic activity. Photocatalytic results show that while BiVO4 produces negligible gaseous products, Ag-sputtered composites generate CO and CH4 (with higher Ag loadings increasing yields). This outcome is attributed to heterojunction formation within the composites. BiVO4 generates protons from H2O oxidation, while SPR decay in Ag NPs supplies hot electrons. Both then drive CO2 reduction to CH4, CO, and O2View this paper
