Converting CO₂ into value‐added chemicals or fuels by electrochemical CO₂ reduction reaction (CO₂RR) has aroused great interest, whereas designing highly active and selective electrocatalysts is still a challenge. Herein, a novel kind of electrochemical catalyst composed with SnO₂ and organic carbon (OC), named as SnO₂/OC, was facilely constructed for CO₂RR. The obtained SnO₂/OC exhibits both high faradaic efficiency for formate (∼75 %) and carbon products (∼95 %) as well as excellent stability. High surface area with hierarchically porous structure and the homogeneous formation of Sn−O−C linkages in SnO₂/OC jointly promote the adsorption and activation of CO₂, as well as fast transport of reactants and products.

分层多孔SnO2耦合有机碳用于CO2电还原。

通过电化学还原CO ₂（CO ₂ RR）将CO ₂转化为增值化学品或燃料引起了人们极大的兴趣，而设计高活性和选择性的电催化剂仍然是一个挑战。本文中，为CO ₂ RR简便地构建了一种新型的由SnO ₂和有机碳（OC）组成的电化学催化剂，称为SnO ₂ / OC 。所得的SnO ₂ / OC对甲酸酯（〜75％）和碳产物（〜95％）均显示出高的法拉第效率，并且具有极好的稳定性。具有分级多孔结构的高表面积和SnO _2中均匀形成Sn-O-C键/ OC共同促进了CO ₂的吸附和活化，以及反应物和产物的快速运输。
