It is a still a great challenge to achieve high selectivity of CO₂ reduction reaction (CO₂RR) to methane. In the April 2022 issue of Chem Catalysis, Sargent et al. develop an element-doping strategy to construct highly selective CO₂RR electrocatalysts by disrupting C-C coupling and simultaneously suppressing hydrogen evolution reaction in neutral electrolyte at high current densities.

二氧化碳制甲烷电还原得到帮助

_{实现CO 2}还原反应（CO ₂ RR）制取甲烷的高选择性仍然是一个很大的挑战。在 2022 年 4 月的《化学催化》杂志上，萨金特等人。开发了一种元素掺杂策略，通过破坏CC耦合并同时抑制高电流密度下中性电解质中的析氢反应来构建高选择性CO _{2 RR电催化剂。}
