Carbon Dots Mediated In Situ Confined Growth of Bi Clusters on g‐C3N4 Nanomeshes for Boosting Plasma‐Assisted Photoreduction of CO2

“…The lowest energy barrier for *CO 2 formation on the surface of CNB-2 composites indicates that the g-C 3 N 4 /Bi/CDs configuration is more kinetically favorable for CO 2 -to-CO conversion. [65] The DFT results are consistent with the above spectral analysis results.…”

Advancing the Electrochemistry of Gas‐Involved Reactions through Theoretical Calculations and Simulations from Microscopic to Macroscopic

“…With an increasing demand for real-time detection of catalysts during reaction processes, various in situ characterizations have been developed, which seem to be excellent solutions to this problem. [198][199][200][201][202][203] In situ X-ray spectroscopy can detect the active phase transition, electronic oxidation/spin state, electronic structure, and local environment of catalysts, [204][205][206][207] and in situ vibrational spectroscopy can monitor the structural evolution of catalysts and the composition of intermediates during the catalytic process. [208,209] All of the above information can be predicted by theoretical calculations and simulations while demonstrated by in situ characterizations.…”

Recent development of nanomaterials for carbon dioxide electroreduction

“…From the literatures above, it is obvious that SACs have the best metal utilization compared to other kinds of catalysts. The in situ characterization makes it a good platform to investigate the catalytic properties in atomic level 93 . It has diverse precursors like ZIF, MOF, PCM, COF, or others.…”
