Non-graphitized carbon/Cu₂O/Cu⁰ nanohybrids with improved stability and enhanced photocatalytic H₂ production.

ABSTRACT: Cu₂O is a highly potent photocatalyst, however photocorrosion stands as a key obstacle for its stability in photocatalytic technologies. Herein, we show that nanohybrids of Cu₂O/Cu⁰ nanoparticles interfaced with non-graphitized carbon (nGC) constitute a novel synthesis route towards stable Cu-photocatalysts with minimized photocorrosion. Using a Flame Spray Pyrolysis (FSP) process that allows synthesis of anoxic-Cu phases, we have developed in one-step a library of Cu₂O/Cu⁰ nanocatalysts interfaced with nGC, optimized for enhanced photocatalytic H₂ production from H₂O. Co-optimization of the nGC and the Cu₂O/Cu⁰ ratio is shown to be a key strategy for high H₂ production, > 4700 μmo
