A notable trend in OER activity on transition metal phosphide pre-catalysts is reported. Remarkably, the tri-metallic FeCoNiP exhibit exceptional apparent and intrinsic activities, outperforming many non-precious catalysts reported previously.
Synergistic coupling of ruthenium with cobalt phosphide can significantly boost the hydrogen evolution performance hybrid catalysts in a wide pH range.
Atomically dispersed M-N-C (M refers to transition metals) materials represent the most promising catalyst alternatives precious metal Pt for electrochemical reduction of oxygen (ORR), yet genuine active sites in remain elusive. Here, we develop a two-step approach fabricate Cu-N-C single-atom catalysts with uniform and well-defined Cu2+-N4 structure that exhibits comparable activity superior durability comparison Pt/C. By combining operando X-ray absorption spectroscopy theoretical...
Abstract Single-atom catalysts (SACs) have emerged as a frontier in heterogeneous catalysis due to the well-defined active site structure and maximized metal atom utilization. Nevertheless, robustness of SACs remains critical concern for practical applications. Herein, we report highly active, selective robust Ru SAC which was synthesized by pyrolysis ruthenium acetylacetonate N/C precursors at 900 °C N 2 followed treatment 800 NH 3 . The resultant 1 -N exhibits moderate capability hydrogen...
Single atom catalysts possess attractive electrocatalytic activities for various chemical reactions owing to their favorable geometric and electronic structures compared the bulk counterparts. Herein, we demonstrate an efficient approach producing single copper immobilized MXene CO2 reduction methanol via selective etching of hybrid A layers (Al Cu) in quaternary MAX phases (Ti3(Al1–xCux)C2) due different saturated vapor pressures Al- Cu-containing products. After Al layers, Cu atoms are...

Herein, we the first time report novel template-free preassembly strategy to fabricate hollow graphitic carbonitride spheres single Cu atoms mounted via thermal polymerization supramolecular preassemblies composed melamine-Cu complex and cyanuric acid. Atomically dispersed Cu-N3 moieties were unambiguously confirmed by spherical...
This perspective illustrates the electromagnetic induction heating technology for a rational heat control in catalytic heterogeneous processes. It mainly focuses on remarkable advantages of this approach terms process intensification, energy efficiency, reactor setup simplification, and safety issues coming from use radio frequency heated susceptors/catalysts fixed-bed reactors under flow operational conditions. is real enabling that allows to go beyond bounds, reducing inefficient transfer...
Single-atom catalysts (SACs) have shown superior activity and/or selectivity for many energy- and environment-related reactions, but their stability at high site density under reducing atmosphere remains unresolved. Herein, we elucidate the intrinsic driving force of a Pd single atom with (up to 5 wt %) atmosphere, its unique catalytic performance hydrogenation reactions. In situ experiments calculations reveal that atoms tend migrate into surface vacancy-enriched MoC during carburization...

Abstract It is widely accepted that single Ni atoms coordinated with N can highly efficiently promote CO 2 electroreduction to CO. Very recently, probably due limited access high‐angle annular dark‐field scanning transmission electron microscopy (HAADF‐STEM) techniques, a misleading conclusion nitrogen‐doped carbon‐encapsulated nanoparticles (NPs) possess activity similar of was reported and quickly followed by several reports. The current contribution aims end this performing well‐designed...
Developing highly efficient catalyst for selective oxidation of benzene to phenol (SOBP) with low H2O2 consumption is desirable practical application, but challenge remains. Herein, we report unique single-atom Cu1-N1O2 coordination-structure on N/C material (Cu-N1O2 SA/CN), prepared by water molecule-mediated pre-assembly-pyrolysis method, can efficiently boost SOBP reaction at a 2:1 H2O2/benzene molar ratio, showing 83.7% high conversion 98.1% selectivity. The sites provide preponderant...
Cu-catalyzed electrochemical CO2 reduction reaction (CO2RR) to multi-carbon (C2+) products is often plagued by low selectivity because the adsorption energies of different intermediates are in a linear scaling relationship. Development Cu-based bimetallic catalysts has been considered as an attractive strategy address this issue; however, conventional avoid metals with strong CO prevent surface poisoning. Herein, we demonstrated that limiting amount Co CuCo can enhance C2+ product...
