dc.description.abstract | Efficient photocatalytic production of H2O2 as a promising solar fuel from H2O and O-2 in water has been achieved by the combination of bismuth vanadate (BiVO4) as a durable photocatalyst with a narrow band gap for the water oxidation and a cobalt chlorin complex (Co-II(Ch)) as a selective electrocatalyst for the two-electron reduction of O-2 in a two-compartment photoelectrochemical cell separated by a Nafion membrane under simulated solar light illumination. The concentration of H2O2 produced in the reaction solution of the cathode cell reached as high as 61 mM, when surface-modified BiVO4 with iron(III) oxide(hydroxide) (FeO(OH)) and Co-II(Ch) were employed as a water oxidation catalyst in the photoanode and as an 02 reduction catalyst in the cathode, respectively. The highest solar energy conversion efficiency was determined to be 6.6% under simulated solar illumination adjusted to 0.05 sun after 1 h of photocatalytic reaction (0.89% under I sun illumination). The conversion of chemical energy into electric energy was conducted using H2O2 produced by photocatalytic reaction by an 11202 fuel cell, where open-circuit potential and maximum power density were recorded as 0.79 V and 2.0 mW cm(-2), respectively. | * |
