Strongly Coupled Ag/Sn-SnO₂ Nanosheets Toward CO₂ Electroreduction to Pure HCOOH Solutions at Ampere-Level Current.

ABSTRACT: Electrocatalytic reduction of CO₂ converts intermittent renewable electricity into value-added liquid products with an enticing prospect, but its practical application is hampered due to the lack of high-performance electrocatalysts. Herein, we elaborately design and develop strongly coupled nanosheets composed of Ag nanoparticles and Sn-SnO₂ grains, designated as Ag/Sn-SnO₂ nanosheets (NSs), which possess optimized electronic structure, high electrical conductivity, and more accessible sites. As a result, such a catalyst exhibits unprecedented catalytic performance toward CO₂-to-formate conversion with near-unity faradaic efficiency (≥ 90%), ultrahigh partial current density (2,000 mA cm^-2), and superior long-term stability (200 mA cm
