α-Fe2O3/Nb2O5/C Nanorods for Selective Photoelectrocatalytic Oxidation of 5-Hydroxymethylfurfural under Solar Light

“…The growth of global energy demand and concerns about environmental issues have greatly promoted the development of clean and sustainable energy sources, such as hydrogen energy and fuel cells. − Among them, photo­(electro)­catalytic (PEC) water splitting of hydrogen is a promising way to produce clean fuels and replace fossil fuels . Given that solar energy consists of 43% visible light, the development of visible-light-driven photo­(electro)­catalytic systems for splitting water into H 2 and O 2 offers a promising strategy for harvesting sunlight and converting it into clean fuels. − However, multielectron transfer water oxidation always suffers from high overpotential and slow reaction kinetics, which slows down or even inhibits the production of H 2 . , To solve this problem, most studies add hole scavengers to the reaction system, which leads to a loss of catalyst oxidation capacity and an increase in production costs. , Adding biomass to the photoelectric system can not only improve the reaction rate of the oxidation process and promote the hydrogen evolution reaction, but also increase the added value of the production process by oxidizing biomass into fine chemicals under environmental conditions …”
