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 […]

Chem Sci: Identification of Pt-based Catalysts for Propane Dehydrogenation via a Probability Analysis

The intrinsic errors due to functionals are always a concern on the reliability of the predicted catalytic performance by density functional theory. This paper describes a probability-based computational screening study, which has successfully identified an optimal bimetallic alloy (Pt3In) for propane dehydrogenation reaction (PDH). Considering DFT uncertainty, Pt3In was found to get an activity comparable […]

JPCC: Coverage Effect on the Activity of the Acetylene Semihydrogenation over Pd–Sn Catalysts: A Density Functional Theory Study

The existence of acetylene impurities in ethylene feedstock is harmful to downstream polymerization reactions. The removal of acetylene can be achieved via semihydrogenation reaction, which is normally catalyzed by Pd-based catalysts. This paper describes the coverage effect on the activity of acetylene hydrogenation reactions over Pd and PdSn alloy surfaces. High-coverage models are presented to […]

Chem Sci: On the role of Ce in CO2 adsorption and activation over lanthanum species

La2O3 exhibits good performance for various catalytic applications, such as oxidative coupling of methane (OCM) and dry reforming of methane (DRM), during which coke formation may lead to the deactivation of catalysts. Typically, the reaction between CO2 adsorbed on La2O3 and coke is the rate-determining step of the coke elimination process. This paper describes the […]

Highlighted by Materials Views China (Wiley): “产物可调的Pd-Cu双金属二氧化碳电还原催化剂”

Electrochemical conversion of carbon dioxide (electrochemical reduction of carbon dioxide) to value‐added products is a promising way to solve CO2 emission problems. This paper describes a facile one‐pot approach to synthesize palladium–copper (Pd–Cu) bimetallic catalysts with different structures. Highly efficient performance and tunable product distributions are achieved due to a coordinative function of both enriched […]
