Highly dispersed ruthenium precursors via a supramolecular self-assembly assisted synthesis of uniform ruthenium nanoparticles with excellent HER performance.

Understanding the Atomic and Defective Interface Effect on Ruthenium Clusters for the Hydrogen Evolution Reaction

“…284.9 (3d 3/2 ) in the Ru 3d XPS spectrum (Figure S21) both confirm the successful incorporation of the Ru(0) cluster on CNT−V−Fe. 7,41 Based on the Fe K-edge XANES of CNT− V−Fe−Ru (Figure 2e), the rising-edge position at ca. 7117.1 eV and the obvious pre-edge peaks at ca.…”

Highly Dispersed Quasi-1 nm Ruthenium Nanoclusters on Hierarchical Nitrogen-Doped Carbon Nanocages Constructed by Surface-Constrained Sintering for Alkaline Hydrogen Evolution

“…This phenomenon can be understood as follows. For the adsorption-annealing process, initially, the Ru species are highly dispersed on the surface of hNCNC due to the interaction between the Ru species and the abundant surface N dopants of the hNCNC (Figure S3); the post-annealing results in the migration of Ru species within a certain area determined by the competition between Ru migration kinetic energy and metal–support interaction, resulting in the sintering of Ru species in this area. , Such a surface-constrained sintering of Ru species ensures a uniform size and distribution of Ru nanoclusters. When the Ru mass loading on hNCNC is increased, this surface-constrained sintering method can still result in the uniform distribution of Ru species (Figure S7).…”
