Abstract

Abstract Acidic electrochemical CO 2 conversion is a promising alternative to overcome the low CO 2 utilization. However, over-reliance on highly concentrated K + to inhibit the hydrogen evolution reaction also causes (bi)carbonate precipitation to interfere with catalytic performance. In this work, under the screening and guidance of computational simulations, we present a carbon coated tip-like In 2 O 3 electrocatalyst for stable and efficient acidic CO 2 conversion to synthesize formic acid (HCOOH) with low K + concentration. The carbon layer protects the oxidized In species with higher intrinsic activity from reductive corrosion, and also peripherally formulates a tip-induced electric field to regulate the…
