Highlighted by Chemistry World: Carbon dioxide recycling on the ball

Cocatalysts on the outside and inside of hollow spheres trigger photocatalytic carbon dioxide reduction to syngas ‘Unlike previous ones, our cocatalyst structure is completely separated by a TiO2 shell, enabling electrons and holes generated by TiO2 to flow in opposite directions, which greatly supresses charge carrier recombination,’ Gong tells Chemistry World. Irradiation by solar light […]

Tunable Syngas Production from Photocatalytic CO2 Reduction with Mitigated Charge Recombination Driven by Spatially Separated Cocatalysts

Photocatalytic CO2 reduction represents a sustainable route to generate syngas (the mixture of CO and H2 ), which is a key feedstock to produce liquid fuels in industry. Yet this reaction typically suffers from two limitations: unsuitable CO/H2 ratio and serious charge recombination. This paper describes the production of syngas from photocatalytic CO2 reduction with […]

The nature of loading-dependent reaction barrier over mixed RuO2/TiO2 catalysts

Mixed-metal oxides are one of the most frequently used catalysts in chemical industry, because the superior catalytic reactivity can be achieved by taking advantage of the synergetic effects of their parent oxides. However, the interfacial electronic interactions between metal oxides remain unclear, because of their structural complexity. This paper describes the modulation of catalytic performance […]

Energy Environ Sci: Efficient and Robust CIGS Photocathodes for Solar Water Splitting

Chalcopyrite thin film absorbers such as Cu(In,Ga)Se2 (CIGS) exhibit excellent solar energy conversion efficiency, particularly when coupled with CdS to form an excellent p-n junction. An increasing number of investigations have focused on adopting protective layers and cocatalysts for chalcopyrite/CdS to improve its stability and surface reaction kinetics. However, satisfactory performance has yet not been […]
