Abstract Supported metal nanoparticles are the most widely investigated heterogeneous catalysts in catalysis community. The size of nanostructures is an important parameter influencing activity constructed catalysts. Especially, as coordination unsaturated atoms always work catalytically active centers, decreasing particle catalyst can greatly boost specific per atom. Single‐atom (SACs), containing single anchored on supports, represent utmost utilization metallic and thus maximize usage...
Modular optimization of metal-organic frameworks (MOFs) was realized by incorporation coordinatively unsaturated single atoms in a MOF matrix. The newly developed can selectively capture and photoreduce CO2 with high efficiency under visible-light irradiation. Mechanistic investigation reveals that the presence Co greatly boost electron-hole separation porphyrin units. Directional migration photogenerated excitons from to catalytic centers witnessed, thereby achieving supply long-lived...
Graphitic carbon nitride (g‐C 3 N 4 ) has recently emerged as an attractive photocatalyst for solar energy conversion. However, the photocatalytic activities of g‐C remain moderate because insufficient solar‐light absorption and fast electron–hole recombination. Here, defect‐modified (DCN) photocatalysts, which are easily prepared under mild conditions show much extended light with band gaps decreased from 2.75 to 2.00 eV, reported. More importantly, cyano terminal CN groups, acting...

Low efficiency and poor stability are two major challenges we encounter in the exploration of non-noble metal electrocatalysts for hydrogen evolution reaction (HER) both acidic alkaline environment.

The optimized catalyst exhibited remarkable...
Water splitting represents a promising technology for renewable energy conversion and storage, but it is greatly hindered by the kinetically sluggish oxygen evolution reaction (OER). Here, using Au-nanoparticle-decorated Ni(OH)2 nanosheets [Ni(OH)2-Au] as catalysts, we demonstrate that photon-induced surface plasmon resonance (SPR) excitation on Au nanoparticles could significantly activate OER catalysis, specifically achieving more than 4-fold enhanced activity meanwhile affording markedly...

The surface-plasmon effect iron particles proposed excite molecules, thereby facilitates final reaction activity. As a service our authors readers, this journal provides supporting information supplied by authors. Such materials are peer...
The crystal phase of metal nanocatalysts significantly affects their catalytic performance. Cu-based nanomaterials are unique electrocatalysts for CO2 reduction reaction (CO2RR) to produce high-value hydrocarbons. However, studies date limited the conventional face-centered cubic (fcc) Cu. Here, we report a phase-dependent behavior Cu, after successful synthesis high-purity 4H Cu and heterophase 4H/fcc using Au as templates, respectively. Remarkably, obtained unconventional structures...
Understanding the reaction mechanism for catalytic process is essential to rational design and synthesis of highly efficient catalysts.
