Solar photocatalysis is the most ideal solution to global energy concerns and environmental deterioration nowadays. The heterojunction combination has become one of successful effective strategies design manufacture composite photocatalysts. Heterojunction structures are widely documented markedly improve photocatalytic behavior materials by enhancing separation transfer photogenerated charges, widening light absorption range, broadening redox potentials, which attributed presence both build-in electric fields at interface two different complementarity between electron structures. So far, a large number have been reported applied for water splitting, reduction carbon dioxide nitrogen, cleaning, etc. This review outlines recent accomplishments in modification photocatalysts, aiming provide some useful perspectives future research this field.

Опубликована: Июнь 17, 2023

Electrocatalytic hydrogenation (ECH) of organics using water as hydrogen donors has been regarded a green organic reduction technique to replace traditional chemical reactions that use sacrificial chemicals. The development ECH process provides potential applications in the production value-added chemicals owing its low energy consumption, pollution, high safety, and superior sustainability. However, application is limited by conversion rate poor selectivity toward desired products. efficiency can be improved rational design electrocatalysts. This review covers several representative electrocatalytic systems (aldehydes, ketones, phenolic organics, alkynes, organonitrogen compounds) summarizes different mechanisms, followed thorough discussion on modification strategies electrocatalysts are currently adopted enhance catalytic performance. Finally, view current challenges for ECH, we discuss possible future directions field, aiming provide guidance catalyst highly efficient over feedstocks.
