Heterogeneous bimetallic catalysts have broad applications in industrial processes, but achieving a fundamental understanding on the nature of active sites at atomic and molecular level is very challenging due to structural complexity catalysts. Comparing features catalytic performances different entities will favor formation unified structure-reactivity relationships heterogeneous thereby facilitate upgrading current In this review, we discuss geometric electronic structures three representative types (bimetallic binuclear sites, nanoclusters, nanoparticles) then summarize synthesis methodologies characterization techniques for entities, with emphasis recent progress made past decade. The supported nanoparticles series important reactions are discussed. Finally, future research directions catalysis based and, more generally, prospective developments both practical applications.

Designing metal-organic framework (MOF)-based catalysts with superior oxygen evolution reaction (OER) activity and robust durability simultaneously is highly required yet very challenging due to the limited intrinsic their elusive under harsh OER conditions. Herein, a steady self-reconstructed MOF heterojunction constructed via redox electrochemistry topology-guided strategy. Thanks inhibiting effect from hydrogen bonds of Ni-BDC-1 (BDC=1,4-benzenedicarboxylic acid), obatained shows greatly improved low overpotential 225 mV at 10 mA cm-2 , relative totally reconstructed Ni-BDC-3 (332 mV). Density function theory calculations reveal that formed built-in electric field in remarkably optimizes ad/desorption free energy active Ni sites.

Single-atom catalysts (SACs) have attracted considerable attention in heterogeneous catalysis because of their well-defined active sites, maximum atomic utilization efficiency, and unique unsaturated coordinated structures. However, effectiveness is limited to reactions requiring sites containing multiple metal atoms. Furthermore, the loading amounts single-atom must be restricted prevent aggregation, which can adversely affect catalytic performance despite high activity individual The introduction nanoscale particles (NMPs) into SACs (NMP-SACs) has proven an efficient approach for improving performance. A comprehensive review urgently needed systematically introduce synthesis, characterization, application NMP-SACs mechanisms behind superior This first presents classifies different through NMPs enhance SACs. It then summarizes currently reported synthetic strategies state-of-the-art characterization techniques NMP-SACs. Moreover, electro/thermo/photocatalysis, reasons are discussed. Finally, challenges perspectives future design advanced addressed.

Designing N-coordinated porous single-atom catalysts (SACs) for the oxygen reduction reaction (ORR) is a promising approach to achieve enhanced energy conversion due maximized atom utilization and higher activity. Here, we report two Co(II)-porphyrin/ [2,1,3]-benzothiadiazole (BTD)-based covalent organic frameworks (COFs; Co@rhm-PorBTD Co@sql-PorBTD), which are efficient SAC systems O2 electrocatalysis (ORR). Experimental results demonstrate that these COFs outperform mass activity (at 0.85 V) of commercial Pt/C (20%) by 5.8 times (Co@rhm-PorBTD) 1.3 (Co@sql-PorBTD), respectively. The specific activities Co@sql-PorBTD were found be 10 2.5 larger than Pt/C, These also exhibit power density recycling stability in Zn-air batteries compared with Pt/C-based air cathode. A theoretical analysis demonstrates combination Co-porphyrin different BTD ligands affords crystalline electrocatalysts having d-band center positions, leads reactivity differences toward alkaline ORR. strategy, design, electrochemical performance offer pyrolysis-free bottom-up avoids creation random atomic sites, significant metal aggregation, or unpredictable structural features.
