ABSTRACT Nickel (Ni)‐based catalysts are prospective materials for dry reforming of methane (DRM) reaction, but suffer from coke formation and limited activity CO 2 conversion. To improve the reactivity Ni‐based catalysts, a promising strategy is introducing cobalt (Co) metal. Here, we construct highly efficient NiCo sites on CeO support by H plasma, which enables catalyst to obtain remarkable increase in DRM reaction than samples treated conventional reduction. plasma treatment results dispersed alloy nanoparticles high‐concentration oxygen vacancy. These features create large numbers active boost activation CH 4 especially their catalytic reactions, resulting strong resistance reaction.

Abstract The unprecedented increase of atmospheric CO 2 concentration and the associated climate change calls for urgent implementation mitigation approaches. Among various proposed measures, capture from several industrial point sources or directly air its subsequent hydrogenation via renewable H towards value-added products formation has gained particular attention. Specifically, production CH 4 is great importance eventual generation liquid fuels synthetic natural gas, respectively. Herein, an overview state-of-the-art noble non-noble metal-based catalysts employed thermocatalytic (reverse water–gas shift reaction, rWGS) (Sabatier reaction) elaborated. A brief description fundamental considerations initially provided each involving thermodynamic, mechanistic kinetics considerations. Then, recent catalytic studies on rWGS Sabatier reactions over both metal (e.g., oxides, carbides, organic frameworks) are discussed perspective structure–property relationships. Lastly, most important conclusions arising comparative analysis promising summarized complemented with outlooks future directions rational design highly active selective materials process.
