Nontrivial topological surface states (TSSs), which possess extraordinary carrier mobility and are protected by the bulk symmetry, have emerged as an innovative platform to search for efficient electrocatalysts toward hydrogen evolution reaction (HER). Here, a Sn‐based nontrivial metal Ru3Sn7 is prepared using electrical arc melting method. The results indicate that the (001) crystal family of Ru3...
Transition metal carbide compound has been extensively investigated as a catalyst for hydrogenation, for example, due to its noble metal‐like properties. Herein a facile synthetic strategy is applied to control the thickness of atomic‐layer Pt clusters strongly anchored on N‐doped Mo2C nanorods (Pt/N‐Mo2C) and it is found that the Pt atomic layers modify Mo2C function as a high‐performance and robust...
Hierarchical metal nanostructures containing 1D nanobuilding blocks have stimulated great interest due to their abundant active sites for catalysis. Herein, hierarchical 4H/face‐centered cubic (fcc) Ru nanotubes (NTs) are synthesized by a hard template‐mediated method, in which 4H/fcc Au nanowires (NWs) serve as sacrificial templates which are then etched by copper ions (Cu2+) in dimethylformamide...
Freestanding metal nanoclusters can tune, precisely and effectively, the Gibbs free energy (ΔGH) of atomic hydrogen on the surface of materials. This enables the enhancement of hydrogen evolution activity. In this paper, we report a study of freestanding Pd‐Ru distorted icosahedral clusters (ico‐clusters) with less than 600 atoms by using a simple one‐pot synthesis method. This Pd‐Ru ico‐cluster can...
