Abstract
Environmental and energy crises are a major threat to the sustainable growth of the human society, calling for greener technologies such as photocatalysis. Photocatalysis is a solar-driven approach that converts photon energy into chemical energy, yet the conversion efficacy of classical photocatalysis is usually restricted and controlled by the charge carrier’s separation and migration. Enhanced conversion requires suppressed recombination rate and superior redox abilities. From this aspect, the manipulation of heterojunction allows to overcome the drawback of classical photocatalysis. The cascade mechanism follows a dual direct charge migration route, resulting in enhanced redox abilities and efficient mineralization of pollutants. Here, we review photocatalytic material aspects in improving redox ability by cascade charge transfer. We describe the mechanisms and applications of three cascade systems: two type-II cascade systems, mediator-based cascade systems, and dual direct Z-scheme. We highlight the superiority of the direct dual cascade route with a prolonged lifetime of carriers, higher quantum yield, and enhanced redox abilities. Applications to carbon dioxide reduction, hydrogen production by water splitting and pollutant degradation are discussed.
