The Mars–van Krevelen mechanism is the foundation for oxide-catalyzed oxidation reactions and relies on spatiotemporally separated redox steps. Herein, we demonstrate the tunability of this separation with peroxide species formed by excessively adsorbed oxygen, thereby modifying the catalytic activity and selectivity of the oxide.
WebJan 15, 2024 · When a structure has less than an 18 electron count, it is considered electron-deficient or coordinately unsaturated. This means that the compound has empty valence orbitals, making it electrophilic and extremely reactive. If a structure has "too many electrons," that means that not all of the bonds are covalent bonds, and thus some has … WebCatalytic Mechanism and Design Principle of Coordinately Unsaturated Single Metal Atom-Doped Covalent Triazine Frameworks with High Activity and Selectivity for CO2 Electroreduction Lele Gong1, Xiaowei Wang2, Tao Zheng3, Jerry Liu2, Jie Wang2, Yu-Chia Yang2, Jing Zhang3, Xiao Han3, Lipeng Zhang1*, Zhenhai Xia2*
