Ruthenium nanoparticles integrated bimetallic metal–organic framework electrocatalysts for multifunctional electrode materials and practical water electrolysis in seawater

“…49-1568), which is consistent with the TEM findings. 33 Similarly, the observed XRD pattern of these MOF-assisted Ru nanoparticles agrees well with the crystalline character of the Ru nanoparticles. The diffraction peaks are centered at 2 θ values of 43.6° and 69.1° which are similar to those found in face-centered cubic (101) and (110) Ru(0) crystals (JCPDS no.…”

“…3C) of the hierarchical nanostructure demonstrate well-resolved lattice fringes, and the typical interplanar spacings of 0.201 nm and 0.207 nm are well-matched with the (110) and (101) planes of the CoFe nanoparticles, and Ru lattices, respectively. 33,34 The selected area electron diffraction (SAED) patterns shown in Fig. 3D were indexed to the (110) and (101) planes of CoFe nanoparticles and Ru lattices for Ru MOF CoFe nanoarrays.…”

CoFe alloy nanoparticles encapsulated in a 3D honeycomb-like N-doped graphitic carbon framework for photocatalytic CO2reduction

“…55,56 The peaks at 714.2 and 731.2 eV can be attributed to satellites. 57 Impressively, the co-presence of metallic Fe and Co reveals the formation of the CoFe alloy, 58 while the co-existence of Fe 2+ and Co 2+ signals manifests the oxidation occurring on the CoFe/N-GC surface, due to the inevitable exposure to air. 32…”

Se-Doped CoP Nanoneedle Arrays Grown on Carbon Cloth for an Efficient Hydrogen Evolution Reaction

“…H 2 is considered as an ideal sustainable energy source to reduce the use of fossil fuels, because it only generates H 2 O after combustion and possesses high energy density . The water electrolysis technique could transfer solar or wind energy into a hydrogen source through the hydrogen evolution reaction (HER), showing great potential for large-scale generation of H 2 . − To realize such an electrocatalysis H 2 generation route, the key is to explore highly active catalysts with low-price materials. The earth-rich transition metal materials receive intensive attention because of the efficient catalysis activity, diverse compounds, and tuned electronic structure. − For instance, transition-metal-based materials of nitrides, , phosphides, − sulfides, − selenides, , hydroxides, − and carbides , have been researched extensively.…”
