For the first time, catalytic stability of cobalt metal, nitride, and phosphide phases supported on MgO was compared for dry reforming methane. The initial CH4 conversions Co/MgO, Co4N/MgO, Co2P/MgO catalysts were 88.1, 87.7 86.0%, respectively. However, after 15 h testing, these values gradually decreased to 69.9, 75.0 79.4%, Co2P catalyst demonstrated superior Co Co4N catalysts. enhanced attributed its smaller particle size a lower ratio CO2 dissociation rates.
Chiral acyclic α-tertiary amino ketones are widely present in various natural products and pharmaceuticals; however, the direct synthesis of this pharmacophore through a robust strategy still presents significant challenges. The emerging photocatalysis provides powerful approach to construct chemical bonds that difficult form via traditional two-electron pathway. Herein, we developed visible-light-induced chiral Lewis acid-catalyzed highly enantioselective acylation/alkylation aldimines...
Visible light‐mediated enantioselective alkylation of carbonyls with hydrocarbons provides a beneficial access to the synthesis chiral alcohols in terms atom economy. Herein, we disclosed direct asymmetric a‐keto pyrazoleamides as C(sp3)–H donors for preparation tertiary a‐hydroxy amides. Our method operates by synergistic catalysis involving Ir‐based photoredox catalyst and N,N′‐dioxide‐NiBr2 complex enabled addition reaction good excellent yield enantioselectivity (up 87% 97% ee),...
Abstract Plate‐like ZnS/C composite with the uniform combination of ZnS and carbon is obtained by pyrolyzing metal–organic framework precursors which consist Zn 2+ sulfur‐containing organic ligand used for high‐performance anode materials in Li‐ion batteries. The synthesized cannot only improve conductivity, but also efficiently buffer large volume change during charge/discharge process, meanwhile mainly provides specific capacity. Typically, after 80 cycles, reversible capacity can maintain...
This study reports ultraviolet (UV) photodetectors based on CuGaO 2 (CGO) nanoplates (NPs) and Zn‐doped CGO (CZGO) NP/ZnO nanowire (NW) heterojunctions. The vertical arrays of ZnO NWs are uniformly grown the surface hexagonal CZGO NPs form a high‐density p–n junction. heterojunctions have better optoelectronic performance parameters than pure NPs. Especially, responsivity value NW reaches 0.12 A W −1 , photo‐to‐current ratio is estimated to be 4.5. work offers new idea for rational design...
Abstract Through a stepwise synthesis, intercalation followed by chemical vapor deposition (CVD) method, WP nanorods have been grown on the surface of WS 2 /C composite. Compared to /C, nanorods@WS demonstrate better hydrogen evolution reaction (HER) activity and long‐term chronopotentiometric stability as well suitability in both acid electrolyte alkaline electrolyte. In order uncover enhanced HER property reason, systematic characterizations were applied assist analyzing. The used include...
We demonstrate CuCrO2 (CCO) nanoparticle (NP)–polyimide (PI) composite film as a saturable absorber (SA) to regulate the output characteristics of passively Q-switched fiber laser at 1.55 μm. Based on reverse and absorptions CCO NP–PI film, expressed two stages with increase pump power for substantial performance enhancement. Reverse saturation absorption is observed introduce appropriate cavity loss, which constructs effective pathways promoting both modulation depth over threshold degree,...
A novel P-doped Co4N/γ-Al2O3 catalyst was firstly designed for dry reforming of methane (DRM). It found that the use P doping can enhance its coking resistance, which might be due to a decrease in CH4 dissociation ability and an increase CO2 ability, as well cobalt species capable interacting with alumina.
This study reports the synthesis of Zn‐doped hexagonal CuGaO 2 (CGO) nanoplates (NPs) and CuGa 1− x Zn O NPs/ZnO nanowires (NWs) array heterostructures through a hydrothermal method. Remarkably, absorption properties NPs show three regions which can be ascribed to direct bandgap absorption, defect level localized surface plasmon resonance (LSPR) absorption. A dramatically increased LSPR peak is induced by CGO fabricated in high precursor concentration conditions, intensity infrared region...
