using spectroelectrochemical monitoring, where photochemistry assists the cathodic activation of precursor complexes [Mn(CO)3(2,2使-bipyridine)Br] and [Mo(CO)4(6,6使-dimethyl2,2使-bipyridine)] to lower the catalytic overpotential needed to trigger the electrocatalytic reduction of CO2 to CO. ...
CO2 was converted to CO and CH4,the main product was CO at low temperature(100% of CO selectivity at 250 ℃over 0.5% Pt / TiO2).Increase of reaction temperature led to increase of CH4 selectivity from 0 to 60.94% when reaction temperature rose from 250 to 450 ℃ over 1.5% Pt / TiO2...
Carbon dioxide conversion into valuable products using photocatalysis and electrocatalysis is an effective approach to mitigate global environmental issues and the energy shortages. Among the materials utilized for catalytic reduction of CO2, Cu-based materials are highly advantageous owing to their widespread...
cells5. In addition, the conversion of CO2to formic acid is believed to be the first and indispensable step in the reduction of CO2to other chemicals or fuels6, such as methanol, methane, or other hydrocarbons, and a fundamental understanding of this process is thus essential for C1 ...

Many research efforts into CO2 reduction to valuable products are motivated by a desire to reduce the atmospheric CO2 concentration. However, it is unclear how laboratory-scale catalytic performance translates to the goal of reducing CO2. In this Perspec
Carbon dioxide reduction (CRR) is an attractive strategy for alleviating global warming and producing valuable fuels. In this work, we study the catalytic conversion of CO2 to C1-C3 products on boron nanosheet in the presence of compressive strain by using density functional theory. Thermodynamic an...
CO2reductionmethanolOxygen vacancies play a vital role in the adsorption, activation, and subsequent reduction of CO2to methanol. This work presents the preparation of two-dimensional Bi2WO6nanosheets with different oxygen vacancy concentrations (BWO-OV1, BWO-OV2, and BWO-OV3) and the evaluation ...
We show that direct bonding between ZrO2 and Cu particles is mandatory for the catalytic reduction of CO2 to methanol with Cu-UiO-66 catalysts. Thus, the nanoscopic Zr6Ox represents an upper limit to generate a maximum concentration of such an interface. We conclude that constituents of the Zr...
