Synergetic interaction between neighboring platinum and ruthenium monomers boosts CO oxidation

Abstract

The synergetic effect between neighboring Pt and Ru monomers supported on N vacancy-rich g-C3N4 promotes the catalytic CO oxidation.

Densely Populated Single Atom Catalysts

“…In addition to the electrocatalytic reactions mentioned above, SACs have also been reported to be used in other catalytic reactions, including NRR, WGSR, methane reforming, methanol steam reforming, CO oxidation, benzene oxidation, acetylene hydrogenation, and so on. Shan et al reported an atomically dispersed Rh on the zeolite (Rh/ZSM‐5) catalyst, which can convert methane into methanol or acetic acid in liquid phase mild oxidation at 150 °C.…”

“…The use of a support with high specific surface area is another efficient way to prepare SACs with high mass loading, since the strong electronic or covalent bond between the metal atom and support could prevent the aggregation of high surface energy single atoms. In addition, reasonable design of the atomic structure between the single atoms and substrate by tuning the metal‐support interaction can improve the intrinsic activity of the catalysts …”

Synergistic adsorptions of Na2CO3and Na2SiO3on calcium minerals revealed by spectroscopic andab initiomolecular dynamics studies

“…At the moment, although the adsorption of Na 2 SiO 3 species has been considerably investigated, 29,[32][33][34][35] very few studies have been conducted on the Na 2 CO 3 /Na 2 SiO 3 system in otation 17,28,31,36 and the synergistic effects exhibited by this reagent combination are still poorly understood. Some authors have successfully investigated surface reactivity and synergistic adsorptions/ reactions by Fourier transform infrared spectroscopy (FTIR), [37][38][39][40] by X-ray photoelectron spectroscopy (XPS), [41][42][43] and by ab initio molecular dynamics (AIMD) 37,[44][45][46] with couplings between the above-mentioned techniques. In the present study, we use a combination of diffuse reectance infrared Fourier transform spectroscopy (DRIFTS), XPS, and AIMD simulations to gain an understanding of the molecular mechanisms involved in the Na 2 SiO 3 adsorption onto bare surfaces and onto surfaces prior treated with Na 2 CO 3 .…”

Surface Reorganization on Electrochemically‐Induced Zn–Ni–Co Spinel Oxides for Enhanced Oxygen Electrocatalysis

“…Herein, the * indicates adsorbed intermediates. In O* and OOH* configuration (Figure f and g), the electrons (sky blue region) can be effectively aggregated between the Co−O bond or O−O bond, which contributes to the activation of a transition state . The Co atom of V Zn ‐ZNCO bound to O was without an external potential at the first step: O 2 (g) + H 2 → OOH* decline in free energy by −1.96 eV (ZNCO: −2.11).…”
