Application of NMAs in electrocatalysis and photoelectrocatalysis. a) Electrocatalytic performance of the EOR with commercial and various aerogel catalysts in dark condition. The solid and dashed lines represent the forward and backward scans, respectively. b) The dependence of I f for the Au‐Pd and Au‐Pt aerogels on the power density of the light. c) Summarized I f and I f/I b of various catalysts. The suffix 0, 1, and 2 denotes that the test was conducted under a light illumination with the power density of 0, 64.1, and 133.6 mW cm−2, respectively. d) The current retention of commercial and various aerogel catalysts under −0.23 V vs. AgCl/Ag in dark condition. All tests were performed in nitrogen‐saturated 1.0 m KOH+1.0 m ethanol aqueous solution.
