摘要：

Localized surface plasmon resonances in plasmonic nanoparticles enable effective photon harvesting and generate energetic electrons and holes. However, fast charge recombination and surface contamination due to reactant-involved synthesis can significantly hinder the activity. Herein, we report a facile, solution-processed synthesis of hybrid uncoated silver nanoparticles combined with silicon nanocrystals to address these issues. The resulting hybrid nanocolloid exhibits enhanced photocatalytic CO2 reduction, achieving 1552 mu mol g(-1) and 100% selectivity for CO production.
