Edge-Site Co–N_x Model Single-Atom Catalysts for CO₂ Electroreduction

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(11), P. 8446 - 8455

Published: May 15, 2024

Metal–nitrogen–carbon single-atom catalysts with metal sites at the edge of carbon layers are widely used in electrocatalytic processes such as CO2 reduction. For prepared pyrolysis methods, local structure sites, including type ligands and coordination number, cannot be precisely controlled, making it difficult to investigate relationship between properties structure. In this work, Co–Nx complexes 2–4 pyridinic anchored black conjugated pyrazine linkers model edge-site Co catalysts. Only Co–N4 catalyst shows high selectivity toward CO electroreduction, turnover frequency 1 order magnitude higher than that Co–N2 Co–N3 Compared site stronger adsorption COOH species weaker H2O H atom due low-spin electron configuration, which rationalizes reduction activity low hydrogen evolution catalyst.

Efficient and multiple CO2 utilization into high-value-added chemicals holds significant importance in carbon neutrality industry production. However, most catalysis systems generally exhibit only one type of transformation with the efficiency to be improved. The restricted abundance active catalytic sites or an inefficient rate these results constraint. Consequently, we designed constructed two metal hydrogen-bonded organic frameworks (M-HOFs) {[M3(L3–)2(H2O)10]·2H2O}n (M = Co (1), Ni (2); L 1-(4-carboxyphenyl)-1H-pyrazole-3,5-dicarboxylic acid) this research. 1 2 are well-characterized, both show excellent stability. networks connected by hydrogen bonds enhance structural flexibility create accessible Lewis acidic sites, promoting interactions between substrates centers.

Incorporation of Pd Single‐atom Sites in Perovskite with an Excellent Selectivity toward Photocatalytic Semihydrogenation of Alkynes

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: unknown

Published: July 27, 2024

Abstract Semihydrogenation is a crucial industrial process. Noble metals such as Pd have been extensively studied in semihydrogenation reactions, owing to their unique catalytic activity toward hydrogen activation. However, the overhydrogenation of alkenes alkanes often happens due rather strong adsorption on active phases. Herein, we demonstrate that incorporation phases single‐atom sites perovskite lattices SrTiO 3 can greatly alternate electronic structure and coordination environment facilitate desorption than further hydrogenation. Furthermore, incorporated be well stabilized without sintering by host–guest interaction with during activation H species hydrogenation reactions. As result, (Pd‐SrTiO ) exhibits an excellent time‐independent selectivity (>99.9 %) robust durability for photocatalytic phenylacetylene styrene.
