Dual-atom catalysts, particularly those with heteronuclear active sites, have the potential to outperform well-established single-atom catalysts for oxygen evolution reaction, but underlying mechanistic understanding is still lacking. Herein, a large-scale density functional theory employed explore feasibility of *O-*O coupling mechanism, which can circumvent scaling relationship improving catalytic performance N-doped graphene supported Fe-, Co-, Ni-, and Cu-containing dual-atom namely,...
The enormous complexity of the carbon material family has provoked a phenomenological approach to develop its potential in different applications. Although electronic, chemical, mechanical, and magnetic properties materials have been widely discussed based on defect control engineering, there is still lack fundamental understanding surface chemistry, which leads many controversial conclusions. Here, by analyzing various defects surface, some commonly neglected aspects misunderstandings this...
Nanocarbons have been extensively used as metal-free alternatives to metal catalysts in many oxidative processes owing their functional groups or defects, which the activation ability toward oxygen molecules.
Three hexatungstates ([(C4H9)3NCH3]2W6O19, [(C8H17)3NCH3]2W6O19, [(C12H25)3NCH3]2W6O19) have been synthesized and characterized. The were dissolved in the hydrophobic 1-octyl-3-methylimidazolium hexafluorophosphoric ([Omim]PF6) ionic liquid (IL) forming a water-in-IL emulsion system with aqueous hydrogen peroxide. Catalytic oxidation of sulfur-containing model oil real gasoline was studied under different conditions this system. multiphase reaction new IL made for easy separation exhibited...
The explicit roles of the hardly avoidable oxygen species on carbon materials in various fields remain contentious due to limitations characterization techniques, which lead a lack fundamental understanding surface chemistry. This study delves exhaustively into comprehension features different oxygen-modified carbons through dynamic evolution surficial functional groups. Significant differences thermal stability and electronic properties among are elucidated via situ characterizations...
Abstract Designing heterogeneous metal‐free catalysts for hydrogenation is a long‐standing challenge in catalysis. Nanodiamond‐based carbon materials were prepared that are surface‐doped with electron‐rich nitrogen and electron‐deficient boron. The two heteroatoms directly bonded to each other form unquenched Lewis pairs infinite π‐electron donation from the surrounding graphitic structure. Remarkably, these can split H 2 + /H − pairs, which subsequently serve as active species of different...
By taking inspiration from the catalytic properties of single-site catalysts and enhancement performance through ionic liquids on metal catalysts, we exploited a scalable way to place single cobalt ions carbon-nanotube surface bridged by polymerized liquid. Single dispersed coordinated liquid are used as heterogeneous for oxygen evolution reaction (OER). Performance data reveals high activity stable operation without chemical instability.
An interface microenvironment between nanocarbon and ionic liquids (ILs) is presented. By an entrapping effect, a few layers of ILs can be finely deposited on the surface nanocarbon, endowing amazingly tailorable properties. The entrapped IL layer, which was believed to unable charred under pyrolysis conditions alone, further carbonized functional carbon layer. C, B, N were confirmed share same hexagonal ring in resultant provides more designable electronic
Due to a lack of fundamental understanding the surface properties nanocarbons, tuning their active sites for higher selectivity oxidative dehydrogenation reactions has always been great challenge carbon catalysis.

Abstract Hydrogen is the emission‐free fuel of future if produced from non‐fossil sources. Biomass gasification or electrolysis water are possible clean routes. For a global application, material solution for electrodes must be sustainable, scalable, and relatively inexpensive compared to current precious metal‐based electrodes. A key requirement sustainable green energy systems that all harmful rare resources utilized in process part closed cycle. Here, carbon‐based electrode hydrogen...
