3D hexapod-shaped Co-ZIFs-S derived co nanoparticles embedded into nitrogen and sulfur co-doped carbon decorated with ruthenium nanoparticles as efficient catalyst for rechargeable lithium oxygen battery

Metal–organic framework derived carbon-encapsulated hollow CuO/Cu2O heterostructure heterohedron as an efficient electrocatalyst for hydrogen evolution reaction

“…Obviously, the Raman D/G intensity ratio ( I D / I G ) of CuO/Cu 2 O@C-10 (0.85) is higher than those of 4 h (0.79), 6 h (0.70), or 8 h (0.72), which shows that carbon defects increased in the Cu-MOF derived carbon framework, and may provide a positive effect to enhance catalytic activity. 45…”

Facile synthesis of cobalt cluster-CoNx composites: synergistic effect boosts electrochemical oxygen reduction

“…2c), demonstrating the existence of Co–N x species within the N-doped carbon matrixes. 26,50–52 And the C 1s peak XPS spectra were deconvoluted into sp 2 hybridized C at 284.5 eV and sp 3 -C at 285.4 eV (Fig. 2d).…”

Boosting the activity and stabilityviasynergistic catalysis of Co nanoparticles and MoC to construct a bifunctional electrocatalyst for high-performance and long-life rechargeable zinc–air batteries

“…7 However, a fundamental obstacle impeding the practical implementation of ZABs is the high overpotential of the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER), which results in slow kinetics in the air cathode. [8][9][10][11][12] For obtaining better performance and durability for ZABs, noble metal catalysts (e.g., Pt, Ru, Ir) are usually applied to ZABs for the process of the ORR/OER. However, due to the limited resources and the high price of these noble metal catalysts, the cost of ZABs will remain higher while applying noble metal catalysts in ZABs.…”
