High-entropy alloys (HEAs) with unique physicochemical properties have attracted tremendous attention in many fields, yet the precise control on dimension and morphology at atomic level remains formidable challenges. Herein, we synthesize PtRuNiCoFeMo HEA subnanometer nanowires (SNWs) for alkaline hydrogen oxidation reaction (HOR). The mass specific activities of SNWs/C reach 6.75 A mgPt+Ru-1 8.96 mA cm-2, respectively, which are 2.8/2.6, 4.1/2.4, 19.8/18.7 times higher than those NPs/C,...
Abstract Preparation of single atom catalysts (SACs) is broad interest to materials scientists and chemists but remains a formidable challenge. Herein, we develop an efficient approach synthesize SACs via precursor-dilution strategy, in which metalloporphyrin (MTPP) with target metals are co-polymerized diluents (tetraphenylporphyrin, TPP), followed by pyrolysis N-doped porous carbon supported (M 1 /N-C). Twenty-four different SACs, including noble non-noble metals, successfully prepared. In...
Single-atom catalysts (SACs) have attracted broad interest recently due to their superior catalytic properties. However, a facile fabrication method for the large-scale synthesis of SACs is still in demand. This study reports mechanochemical approach mass production noble metal SACs. The successful formation atomically dispersed palladium species on zinc oxide (Pd1/ZnO) was verified by aberration-corrected high-angle annular dark-field scanning transmission electron microscopy and X-ray...
Abstract Designing and modulating the local structure of metal sites is key to gain unique selectivity high activity single site catalysts. Herein, we report strain engineering curved atomic iron‐nitrogen boost electrocatalytic activity.

The introduces compressive on supported Fe−N 4 sites. Consequently, 1.5 % compressed bonds exhibit...
Understanding the synergy of Cu0 and Cu+ in hydrogenation reactions is indispensable for reasonably modulating product distributions improving catalyst design. Herein, we investigated dimethyl oxalate on CeZrOx-supported Cu with varying molar ratios nCu+/nCu0. A volcano-type correlation structure activity indicates that selectivity ethylene glycol strongly dependent nCu+/nCu0 ratio, arising from matching rates activation carbonyl group-included reactants H2 Cu0, respectively. The maximal...
With the advantages of a Fenton-inactive characteristic and unique p electrons that can hybridize with O2 molecules, p-block metal-based single-atom catalysts (SACs) for oxygen reduction reaction (ORR) have tremendous potential. Nevertheless, their undesirable intrinsic activity caused by closed d10 electronic configuration remains major challenge. Herein, an Sb-based SAC featuring carbon vacancy-enhanced Sb–N4 active centers, corroborated results high-angle annular dark-field scanning...
DNA-encoded small molecule libraries (DELs) have enabled discovery of novel inhibitors for many distinct protein targets therapeutic value through screening with up to billions unique molecules. We demonstrate a new approach applying machine learning DEL selection data by identifying active molecules from large commercial collection and virtual library easily synthesizable compounds. train models using only apply automated or automatable filters chemist review restricted the removal...
1,2-Dihydromethano[60]fullerene and its congeners have attracted much interest, but they been synthesized only in very low yields because of several insurmountable problems. A new three-stage synthesis involving addition a silylmethylmagnesium chloride to [60]- [70]fullerene oxidation the anionic intermediate with CuCl(2) afforded methano[60]- methano[70]fullerenes 90% 70% overall yield, respectively. The reaction 1,4-diorgano[60]fullerene also proceeded smoothly give diastereomerically pure...
The Co nanoparticles encapsulated inside and nitrogen co-doped carbon catalysts with small particle size homogenous distribution of NPs were elaborately synthesized, which exhibit evidently outstanding activity stability toward ORR/HER.
