Single-atom catalysts (SACs) have arguably become one of the most active frontiers in heterogeneous catalysis for its high atom utilization efficiency21,22, featuring highly tunable active centers with well-defined coordination geometric/electronic structures similar to typical homogeneous catalysts or nanoz...
HEFEI, Oct. 28 (Xinhua) -- A Chinese team, together with scientists from American universities, has created a new strategy to resolve the limitations of single-atom catalysts and increase their potential for effective application, according to the University of Science and Technology of China (UST...
Population (Bader charges)62,63,64,65and Mayer bond order analysis66were performed. As shown in TableS7, charge of Pt single atom slightly decreased from 0.87 to 0.84e, which was consistent with our observation in XPS and XANES. Pt-O bond elongated from 1.96 to 2.03 Å on average,...
single-atom catalystAprotic lithium–oxygen batteries (LOBs) may deliver exceptionally high energy density but struggle to attain rapid reversibility and substantial capacity simultaneously, due to typical surface or solution-formed insulating solid Li2O2. Tuning the structure of Li2O2 to create a large...
The precise structural integration of single-atom and high-entropy-alloy features for energy electrocatalysis is highly appealing for energy conversion, yet remains a grand challenge. Herein, we report a class of single-atom Mo-tailored PdPtNiCuZn high-e
Single-Atom Catalysts for Hydrogen Evolution Reaction 1Introduction With the depletion of fossil fuels (coal, oil, and natural gas), heavily environmental pollution, and climate change, the exploitation of safe, clean, efficient, sustainable, and environmental-friendly energy sources has become a major...
Metal single-atom catalysts (M-SACs) have emerged as an attractive concept for promoting heterogeneous reactions, but the synthesis of high-loading M-SACs remains a challenge. Here, we report a multilayer stabilization strategy for constructing M-SACs in
Regenerable nanozymes with high catalytic stability and sustainability are promising substitutes for naturally-occurring enzymes but are limited by insufficient and non-selective catalytic activities. Herein, we developed single-atom nanozymes of RhN4, V
Single-atom catalysts not only maximize metal atom efficiency, they also display properties that are considerably different to their more conventional nanoparticle equivalents, making them a promising family of materials to investigate. Herein we developed a general host–guest strategy to fabricate various...
Semi-hydrogenation of acetylene in excess ethylene is a key industrial process for ethylene purification. Supported Pd catalysts have attracted most attention due to their superior intrinsic activity but often suffer from low selectivity. Pd single-atom
