Figure 11. STH efficiency of more than 9% in photocatalytic water splitting. (A) Synergetic effect for promoting forward hydrogen-oxygen evolution and inhibiting the reverse hydrogen-oxygen recombination in the photocatalytic overall water splitting (OWS); (B) Image of outdoor photocatalytic OWS system; (C) The corresponding STH efficiency of a 4 cm × 4 cm Rh/Cr2O3/Co3O4-loaded InGaN/GaN NW wafer under concentrated natural solar light (~16,070 mW·cm-2).
