Engineering In/In2O3 Heterointerfaces for Highly Efficient Acidic CO2-to-HCOOH Electroreduction at Ampere-Level Current Density
Efficient acidic CO2 electroreduction to formic acid (HCOOH) offers a promising pathway for chemical manufacturing, yet catalyst stability remains a major obstacle. For example, while In2O3 catalysts exhibit high selectivity toward HCOOH, the cationic In3+ species are prone to reduction to metallic In under harsh aci...
