Constructing asymmetric double-atomic sites for synergistic catalysis of electrochemical CO2 reduction

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Oct. 3, 2023

Elucidating the synergistic catalytic mechanism between multiple active centers is of great significance for heterogeneous catalysis; however, finding corresponding experimental evidence remains challenging owing to complexity catalyst structures and interface environment. Here we construct an asymmetric TeN2-CuN3 double-atomic site catalyst, which analyzed via full-range synchrotron pair distribution function. In electrochemical CO2 reduction, features a with activating two key molecules: operando spectroscopy confirms that Te center activates CO2, Cu helps dissociate H2O. The theoretical results reveal could cooperatively lower energy barriers rate-determining step, promoting proton transfer kinetics. Therefore, displays broad potential range high CO selectivity, improved kinetics good stability. This work presents synthesis characterization strategies catalysts, experimentally unveils underpinning catalysis.

The synthesis of high-performance catalysts for volatile organic compounds (VOCs) degradation under humid conditions is essential their practical industrial application. Herein, a codoping strategy was adopted to synthesize the N-Co3O4-C catalyst with N, C low-temperature ethyl acetate (EA) conditions. Results showed that exhibited great catalytic activity (T 90 = 177 °C) and water resistance (5.0 vol% H2O, T 178 EA degradation. Characterization results suggested C, N weakened Co-O bond strength, increased surface Co3+ Oads species, improved redox ability mobility lattice oxygen which boosted performance Meanwhile, N-doping-induced vacancies could interact vapor generate extra active enhanced resistance. Importantly, based on series characterization technologies, in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), theoretical calculations, synergistic effect systematically investigated elucidated. doping induced increase area weakening adsorption species activation dissociate oxidize EA, forming key intermediate, acid. gaseous form attacking breaking C-C acid accelerate deep oxidation, synergistically facilitated
