a Comparison of Cu2(OH)2CO3 powder loading on carbon paper as electrode before (left) and after (right) reaction. b Cu2(OH)2CO3 tablet as electrode before (left) and after (right) reaction. c H2O2 yield in 50 mL 0.5 M Na2SO4 electrolyte at 3.4 V vs. RHE. d H2O2 yield in 50 mL 0.5 M Na2SO4 electrolyte under different potential. e H2O2 generation rate and faradic efficiency of Cu2(OH)2CO3 tablet under different potential. f I-t curves and FE at 30 min in 8 h of Cu2(OH)2CO3 tablet in 50 mL Na2SO4 electrolyte by refreshing electrolyte per 30 min (16 cycles). Error bars represent the standard deviation of three measurements. Source data for Fig. 1c–f are provided as a Source Data file. The voltage is not iR corrected in all electro-experiments. The mass of the active materials in all comparative experiments is 2 g.
