Transition metal single atom catalysts (SACs) with M
The Sabatier principle is a fundamental concept in heterogeneous catalysis that provides guidance for designing optimal catalysts with the highest activities. For first time, we here report new phenomenon hydrogenation reactions induced by single-atom density at atomic scale. We produce series of Ir (SACs) predominantly Ir1-P4 coordination structure densities ranging from 0.1 to 1.7 atoms/nm2 through P-coordination strategy. When used as hydrogenation, volcano-type relationship between and...
Regulating the density of metal single atoms and exploring interaction among them are showing great potential to further raise performance single-atom catalysts (SACs). Herein, we produce a series Cu SACs with densities ranging from 0.1 2.4 atoms/nm2 find that catalytic activity is proportional in benzene hydroxylation reaction. Mechanistic studies reveal interactions neighboring moieties ultra-high-density SAC alter electronic structures atoms, resulting stronger •OH adsorption, which...
Inter-site interaction in densely populated single-atom catalysts has been demonstrated to have a crucial role regulating the electronic structure of metal atoms, and consequently their catalytic performances.

Taking cobalt as an example, we further produce series Co with varying loadings investigate influence density on performance alkene epoxidation O2. Interestingly, turnover frequency mass-specific activity are...
Introducing oxygen vacancies into Co-based oxides with different surface structures can significantly affect their coordination environments and electronic structures, possibly contributing to the variation of electrocatalytic evolution reaction (OER) activity. Herein, were introduced Co3O4 cubes truncated octahedrons uncover effects facets (001) (111) on intrinsic OER activity oxygen-defective Co3O4. The (001)-faceted exhibited a lower onset overpotential 298 mV than that multifaceted (335...
For single-atom catalysts (SACs), the catalyst supports are not only anchors for single atoms, but also modulators geometric and electronic structures, which determine their catalytic performance. Selecting an appropriate support to prepare SACs with uniform coordination environments is critical achieving optimal performance clarifying relationship between structure property of SACs. Approaching such a goal still significant challenge. Taking advantage strong d-π interaction Cu atoms...
With the development of synthetic methodology, recent breakthroughs have been achieved to prepare metal single-atom catalysts (SACs) with high loadings, leading an emerging class SACs called densely populated or high-density SACs. This type provides not only higher mass-specific activity but also additional interaction among single sites, which can further influence local geometric and electronic structures individual centers thus affect intrinsic active sites. Review examines research...
