Bottom-up construction of efficient active sites in transition metal-nitrogen-carbon (M-N-C) catalysts for oxygen reduction reaction (ORR) from single molecular building blocks remains one the most difficult challenges. Herein, we report a bottom-up approach to produce highly Cu-N4-C catalyst with well-defined Cu-N4 coordination derived small copper complex containing moieties. The moieties were found be covalently integrated into graphene sheets create ORR. Furthermore, activity was boosted...
Abstract Single atom catalysts had been widely used in oxygen evolution reaction (OER) and reduction (ORR). However, the relationship between local coordination environment catalytic activity were unclear. In this work, effect of N‐defect axial halogen atoms on electrocatalytic OER/ORR FeN 4 investigated by density functional theory calculations (DFT). When overpotential was only criterion, 3 Br optimal candidates for OER, followed F, I, Cl Br; also promising ORR. may be excellent ORR an...
Environmentally persistent free radicals (EPFRs) formed on a solid particle surface have received increasing attention because of their toxic effects. However, organic chemical fate regulated by EPFRs has rarely been investigated, and this information may provide the missing link in understanding environmental behavior. Previous studies suggested that reduction transition metals is involved formation. We thus hypothesize an oxidative environment inhibit formation particle-gas interface,...
In this study, the enhancement of photocatalytic activity a graphene oxide/ZnO (GO/ZnO) nanohybrid was achieved via introducing Mg as co-dopant element by co-precipitation method. The Mg-doped ZnO nanoparticles were adsorbed on GO sheets. Compared with catalyses GO/ZnO nanohybrids, GO/Zn1−xMgxO nanohybrids exhibited better activity, in which decomposition rate methyl orange (MO) reached 100% within 60 min. is attributed to Mg-doping and efficient charge transfer photogenerated electrons...
In spite of recent advances in understanding the mechanism coelenterate bioluminescence, there is no consensus about which coelenteramide specie and/or state are light emitter. this study, a systematic investigation geometries and spectra all possible emitters has been performed at TD ωB97XD/6-31+G(d) level theory, including various fluorescent chemiluminescent states vacuum, hydrophobic environment aqueous solution. To deduce most probable form emitter, equilibrium constants for connecting...
Cypridina bioluminescence has been increasingly used in bioimaging, bioanalysis, and biomedicine, due to high quantum yield signal-to-noise ratio. However, there is still no consensus regarding different aspects of the chemiluminescent mechanism this system, which impairs development new applications. Herein, we have a theoretical DFT TD-DFT approach (i) determine identity dioxetanone species responsible for efficient chemiexcitation (ii) identify bioluminescent emitter if light-emission...
Minimizing the use of platinum (Pt) in catalysts for oxygen reduction reaction (ORR) is critical commercial application fuel cells. Here, we report a highly active carbon-supported catalyst with low loading Pt nanoparticles (Pt/C-N, 7.13 wt% Pt), prepared using small molecular complex containing Pt−N4 moieties as precursor. It was confirmed that an average diameter <3 nm were uniformly adsorbed on nitrogen (N)-doped carbon surface by carbothermal composite composed Pt(NH3)42+ ions and via...
Abstract The intervention of endogenous H 2 O via nanozymes provides a potential antitumor‐specific therapy; however, the role nanozyme structure in relation to selective decomposition hydroxyl radicals (•OH) is yet be fully understood, which limits development this therapeutic approaches. Herein, an iron single‐atom (Fe─N Cl ─C SAzyme) reported, prepared through precise Fe─Cl coordination based on construction characteristic Fe‐containing molecule. Fe─N exhibits efficient catalytic (2.19 ×...
