Supported metal nanostructures are the most widely used type of heterogeneous catalyst in industrial processes. The size particles is a key factor determining performance such catalysts. In particular, because low-coordinated atoms often function as catalytically active sites, specific activity per atom usually increases with decreasing particles. However, surface free energy metals significantly particle size, promoting aggregation small clusters. Using an appropriate support material that...
Photoelectron spectroscopy revealed that a 20-atom gold cluster has an extremely large energy gap, which is even greater than of C60, and electron affinity comparable with C60. This observation suggests the Au20 should be highly stable chemically inert. Using relativistic density functional calculations, we found possesses tetrahedral structure, fragment face-centered cubic lattice bulk small structural relaxation. thus unique molecule atomic packing similar to but very different properties.
We develop an N-coordination strategy to design a robust CO2 reduction reaction (CO2RR) electrocatalyst with atomically dispersed Co-N5 site anchored on polymer-derived hollow N-doped porous carbon spheres. Our catalyst exhibits high selectivity for CO2RR CO Faradaic efficiency (FECO) above 90% over wide potential range from -0.57 -0.88 V (the FECO exceeded 99% at -0.73 and -0.79 V). The current density remained nearly unchanged after electrolyzing 10 h, revealing remarkable stability....
High specific activity and cost effectiveness of single-atom catalysts hold practical value for water gas shift (WGS) reaction toward hydrogen energy. We reported the preparation characterization Ir single atoms supported on FeO(x) (Ir1/FeO(x)) catalysts, which is 1 order magnitude higher than its cluster or nanoparticle counterparts even those most active Au- Pt-based catalysts. Extensive studies reveal that accounted ∼70% total containing atoms, subnano clusters, nanoparticles, thus...
AuNi alloy nanoparticles were successfully immobilized to MIL-101 with size and location control for the first time by double solvents method (DSM) combined a liquid-phase concentration-controlled reduction strategy. When an overwhelming approach was employed, uniform 3D distribution of ultrafine (NPs) encapsulated in pores achieved, as demonstrated TEM electron tomographic measurements, which brings light new opportunities fabrication non-noble metal-based NPs throughout interior MOFs. The...
Heteroatom-doped Fe-NC catalyst has emerged as one of the most promising candidates to replace noble metal-based catalysts for highly efficient oxygen reduction reaction (ORR). However, delicate controls over their structure parameters optimize catalytic efficiency and molecular-level understandings mechanism are still challenging. Herein, a novel pyrrole-thiophene copolymer pyrolysis strategy synthesize Fe-isolated single atoms on sulfur nitrogen-codoped carbon (Fe-ISA/SNC) with...
The current industrial ammonia synthesis relies on Haber-Bosch process that is initiated by the dissociative mechanism, in which adsorbed N2 dissociates directly, and thus limited Brønsted-Evans-Polanyi (BEP) relation. Here we propose a new strategy an anchored Fe3 cluster θ-Al2O3(010) surface as heterogeneous catalyst for from first-principles theoretical study microkinetic analysis. We have studied whole catalytic mechanism conversion of to NH3 Fe3/θ-Al2O3(010), find associative first...
Abstract Defects can greatly influence the properties of oxide materials; however, facile defect engineering oxides at room temperature remains challenging. The generation defects in is difficult to control by conventional chemical reduction methods that usually require high temperatures and are time consuming. Here, we develop a room-temperature lithium strategy implant into series nanoparticles including titanium dioxide (TiO 2 ), zinc (ZnO), tin (SnO cerium (CeO ). Our shows advantages...
Surface-supported isolated atoms in single-atom catalysts (SACs) are usually stabilized by diverse defects. The fabrication of high-metal-loading and thermally stable SACs remains a formidable challenge due to the difficulty creating high densities underpinning Here we report that Pt can be through strong covalent metal-support interaction (CMSI) is not associated with support defects, yielding high-loading SAC trapping either already deposited or PtO2 units vaporized from nanoparticles...

Oxygen electrochemistry plays a critical role in clean energy technologies such as fuel cells and electrolyzers, but the oxygen evolution reaction (OER) severely restricts efficiency of these devices due to its slow kinetics. Here, we show that via incorporation lithium ion into iridium oxide, thus obtained amorphous oxide (Li-IrO x) demonstrates outstanding water oxidation activity with an OER current density 10 mA/cm2 at 270 mV overpotential for h continuous operation acidic electrolyte....
