a,b, Buffer effect (a) and Na2Cr2O7 effect (b) on the catalytic conversion of BrO3– to Br– and O2 (reaction 12). The electrolyte was 1.5 M NaBrO3 (7 ml) and the catalyst loading was 50 mg in a and 25 mg in b. c, Catalytic conversion of 1 M bromate solution obtained by bromide electrolysis (Fig. 2b). The catalyst loading was 50 mg. The solid black curve presents the fraction of conversion of bromate to bromide, and the dashed blue curve presents the equivalent electric current.
