Heterojunction between anodic TiO2/g-C3N4 and cathodic WO3/W nano-catalysts for coupled pollutant removal in a self-biased system

Without light or externally applied voltage,a new self-sustained catalytic fuel cell with anodic TiO2/g-C3N4catalyst and cathodicWO3/W nano-catalysts was establishedand generated spontaneous current. Itcan oxidize and reduce different pollutantssimultaneously.
