Solar-driven CO2 conversion to chemical fuels in an aqueous solution is restricted not only by photocatalysts but also mass transfer. Here, a regulatable three-phase interface on porous fixed-bed constructed for efficient C–C coupling photocatalytic reduction. The results show that ∼90% selectivity towards C2+ products obtained Cu/Cd0.5Zn0.5S photocatalyst, with yield of 6.54 μmol/h (an irradiation area 0.785 cm2), while 0.94 19.625 cm2) achieved commonly used suspension reactor. We find...
Abstract Controlling the concentrations of H 2 O and CO at reaction interface is crucial for achieving efficient electrochemical reduction. However, precise control these variables during catalysis remains challenging, underlying mechanisms are not fully understood. Herein, guided by a multi-physics model, we demonstrate that tuning local O/CO achievable thin polymer coatings on catalyst surface. Beyond often-explored hydrophobicity, properties gas permeability water-uptake ability even more...
Indium-based oxides are promising electrocatalysts for producing formate via CO2 reduction reaction, in which *OCHO is considered the key intermediate. Here, we identified that *COOH pathway could be preferential to produce on In2O3 of In/In2O3 heterojunction due synergistic effect oxygen species and vacancy. Specifically, *CO2 were observed related production by situ Raman spectroscopy. The theoretical calculations further demonstrated energy barrier formation was decreased presence...
If combined with renewably generated electricity, electrochemical CO2 reduction (E-CO2R) could be used as a sustainable source of chemicals and fuels. Tandem catalysis approaches are attractive for providing the product selectivity, which would required commercial applications. Here, we demonstrate two-step tandem electrocatalytic E-CO2R efficient conversion intermediate species. The catalyst scaffold is Si(100), etched to form textured surface consisting micron-sized pyramid structures...

This work describes strategy to enhance C product formation in R by utilizing spatial confinement effects. The finite element simulation results suggest that increasing number...
The practical application of electrocatalytic CO2 reduction requires adaptation to the fluctuating voltage output photovoltaic systems. However, potential-induced in-situ reconstruction catalyst complicates control and leads Faradaic efficiency (FE) instability across potential window. Here, we present a redox graphene-supported indium oxide (G-InOx), where rGO effectively regulates surface evolution InOx from In3+ In0 during reactions. multivalent In generated via lowers energy barriers for...
Abstract Electrocatalysts based on high‐valent indium are promising for formate production via CO 2 electroreduction. However, reconstruction often occurs during the reaction progress, resulting in a decline catalytic performance. Here, composite of In O 3 /In S is developed, and its performance exceeds that either individual phase, particularly stability. Analysis morphology, valence state, situ Raman spectroscopy reveals well preserved reaction. Theoretical calculations suggest desorption...

We further developed an optimized using commercial Cu...

Accelerating electrocatalytic water splitting via hydrogen spillover has received increasing attention. However, the underlying mechanism of on evolution is still ambiguous. Herein, a simulation study was carried out to determine role in pH- and potential-dependent over NiCu bimetal catalyst. It found that current density most prominently improved by neutral condition at −0.35 −0.2 V vs reversible electrode. By parameter study, it indicated potential pH could improve effect altering surface...
