Ag Single Atoms Anchored on CeO₂ with Interfacial Oxygen Vacancies for Efficient CO₂ Electroreduction

ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(25), P. 30262 - 30271

Ag single-atom catalysts (SACs) have great potential in selective electrocatalysis of the CO2 reduction reaction (CO2RR) to CO, while it is still a challenge achieve high current density and atom efficiency simultaneously. Here, we present new simple situ adsorption-reduction method prepare SACs supported on CeO2 (Ag1/CeO2). It found that single atoms are anchored through strong metal-support interaction (SMSI), each accompanied with three interfacial oxygen vacancies. This Ag1/CeO2 exhibits performance electrocatalytic CO2RR CO faradaic (FE) >95% under wide range. The turnover frequency (TOF) value can reach 50,310 h-1 at FECO = 99.5% H-cells. Notably, achieves an industrial-grade 403 mA cm-2 97.2% flow cells. Experimental results combined functional theory calculation revealed this superior was mainly ascribed existence vacancies, which lead formation Ag-O-Ce3+ atomic interfaces, activates Ce3+-O structures as synergistic active center Ag, thus promoting adsorption activation reducing barrier *COOH-to-*CO.

2D Metal/Graphene and 2D Metal/Graphene/Metal Systems for Electrocatalytic Conversion of CO₂ to Formic Acid

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(12)

Abstract Efficiently transforming CO 2 into renewable energy sources is crucial for decarbonization efforts. Formic acid (HCOOH) holds great promise as a hydrogen storage compound due to its high density, non‐toxicity, and stability under ambient conditions. However, the electrochemical reduction of (CO RR) on conventional carbon black‐supported metal catalysts faces challenges such low through dissolution agglomeration, well suffering from overpotentials necessity overcome competitive evolution reaction (HER). In this study, we modify physical/chemical properties surfaces by depositing monolayers graphene (M/G) create highly active stable electrocatalysts. Strong covalent bonding between induced hybridization sp d orbitals, especially sharp , orbitals metals near Fermi level, playing decisive role. Moreover, charge polarization in M/G enables deposition another thin metallic film, forming metal/graphene/metal (M/G/M) structures. Finally, evaluating required HCOOH, CO, HER, find that Pd/G, Pt/G/Ag, Pt/G/Au exhibit excellent activity selectivity toward HCOOH production. Our novel 2D hybrid catalyst design methodology may offer insights enhanced reactions electronic mixing other p‐block elements.
