Surface modification of conductive oxide glass (F‐SnO 2 : FTO) anode substrates using 10 oxides was investigated for efficiently producing oxidative hydrogen peroxide (H 2 O 2 ) from water with hydrogen (H 2 ) production at a Pt cathode. Bismuth vanadate (BiVO 4 ) or titanium oxide modification significantly facilitated oxidative H 2 O 2 production in an aqueous solution of bicarbonate (HCO 3 − ) on the anode substrate in the dark. The BiVO 4 ‐supported FTO anode (BiVO 4 /FTO) achieved not only approximately twice the H 2 O 2 generation performance compared with a bare FTO substrate but also high H 2 O 2 accumulation, and the maximum selectivity (η(H 2 O 2 )) and accumulation reached ca . 35 % and 5 mM, respectively.
