“…When the N2 source was re-filled into the reaction cavity, the intermediates are shown to be recovered similarly with the beginning stage. The above results verify that the methanol activation obeys the L-H mechanism under relative low temperatures [7]. In this condition, the surface adsorbed oxygen is adopted as the active oxygen species, which participate in the activation and the DOM (1373 cm −1 ) and carboxyl (1587/1588 cm −1 ) species are produced as the main intermediates.…”

“…3e, f and Table 1). According to the theoretical studies and experiment data involved in this work, we point out that the evident rise in the amount of lattice oxygen species and surface acid sites over the Pt1-CeO2{100} catalyst is possibly the utmost factor for improving the catalytic performance [6][7][8]12]. As shown in Fig.…”

“…For this reason, single atom catalysts (SACs) often possess unprecedented catalytic performance, a trait which in recent years has been capitalized upon and evidenced in several im-portant reactions driven by thermal, electric, and light-energy [3][4][5]. In light of growing concerns associated with the emission of volatile or-ganic compounds (VOCs) [6][7][8][9], several recent publications have de-monstrated the potential of using SACs for the low-temperature de-struction of VOCs [10,11]. We too, recently demonstrated that a Pt1-Co3O4 SAC was exceptionally active for the destruction of oxygenated VOCs [12].…”

“…As such, we consider that it is crucial to design a stable mono-dispersed active interface for thermo-catalytic reactions, over which the single atom sites are anchored to the defected sites through SMSIs. Despite several single atom materials having been de-veloped and utilized for the destruction of VOCs, the intrinsic me-chanism for the oxidation of VOCs and the relationship between cata-lytic performance and electronic structure have been somewhat overlooked [6][7][8][9].…”

Exploring thermally robust single atom catalysts (SACs) is of great significance. Here, we develop a universal strategy for stabilizing Pt atoms on the mono-oxygen vacancies of CeO2 with diverse exposed facets. The sta-bilization mechanism was proposed that the formed Pt-O-Ce interface will be taken into distortion spontaneously to keep thermodynamics stable through strong metal-support interactions. The highest degree of Pt-O-Ce dis-tortion is achieved over Pt1-CeO2{100} material, which exhibits exceptional efficiency and thermal stability for oxygenated hydrocarbon removal. The enhanced adsorption capacity of O2 and methanol confirmed in the distortion interface is seen as another crucial reason for improving the stability of SACs. Methanol oxidation on Pt1-CeO2{100} obeys the L-H mechanism under relatively low temperature and then goes through to the MVK mechanism with temperature increasing. We believe that these results would bring new opportunities in the fabrication of SACs and applications of them in thermal reactions.

Simultaneously Constructing Active Sites and Regulating Mn–O Strength of Ru‐Substituted Perovskite for Efficient Oxidation and Hydrolysis Oxidation of Chlorobenzene

et al. 2022

Chlorinated volatile organic compounds (CVOCs) are a class of hazardous pollutants that severely threaten environmental safety and human health. Although the catalytic oxidation technique for CVOCs elimination is effective, enhancing the catalytic efficiency and simultaneously inhibiting the production of organic byproducts is still of great challenge. Herein, Ru‐substituted LaMn(Ru)O 3+ δ perovskite with Ru–O–Mn structure and weakened Mn–O bond strength has been developed for catalytic oxidation of chlorobenzene (CB). The formed Ru–O–Mn structure serves as favorable sites for CB adsorption and activation, while the weakening of Mn–O bond strength facilitates the formation of active oxygen species and improves oxygen mobility and catalyst reducibility. Therefore, LaMn(Ru)O 3+ δ exhibits superior low‐temperature activity with the temperature of 90% CB conversion decreasing by over 90 °C compared with pristine perovskite, and the deep oxidation of chlorinated byproducts produced in low temperature is also accelerated. Furthermore, the introduction of water vapor into reaction system triggers the process of hydrolysis oxidation that promotes CB destruction and inhibits the generation of chlorinated byproducts, due to the higher‐activity *OOH species generated from the dissociated H 2 O reacting with adsorbed oxygen. This work can provide a unique, high‐efficiency, and facile strategy for CVOCs degradation and environmental improvement.

Solar-driven water splitting to produce clean and renewable hydrogen offers a green strategy to address the energy crisis and environmental pollution. Heterostructure catalysts are receiving increasing attention for photocatalytic hydrogen generation. ZnO/ZnS/CdS and ZnO/CdS heterostructures have been successfully designed and prepared according to two different strategies. By introducing a heterointerface layer of ZnS between ZnO and CdS, a Z scheme charge-transfer channel was promoted and achieved superior photocatalytic performance. A highest hydrogen generation rate of 156.7 μmol g À 1 h À 1 was achieved by precise control of the thickness of the heterointerface layer and of the CdS shell. These findings demonstrated that heterostructures are promising catalysts for solar-driven water splitting, and that heterointerface engineering is an effective way to improve the photocatalytic properties of heterostructures.
