Development of effective technologies for clean and sustainable hydrogen energy has been attracting great attention. Toward this end, an effective and promising approach is based on the electrolysis of water for hydrogen production. To date, the most effective hydrogen evolution reaction (HER) electrocatalysts are Pt-group metals with a low overpotential to generate large cathodic current densities...
Transition metal–carbon hybrids have been proposed as efficient electrocatalysts for hydrogen evolution reaction (HER) in acidic media. Herein, effective HER electrocatalysts based on metal–carbon composites are prepared by controlled pyrolysis of resin containing a variety of heavy metals. For the first time, Cr2O3 nanoparticles of 3–6 nm in diameter homogeneously dispersed in the resulting porous...
Advanced materials for electrocatalytic water splitting are central to renewable energy research. In this study, we describe a two-step reaction for preparing hydrogen evolution reaction (HER) electrodes composed of Pt nanoparticles and MoS2 nanosheets grown on carbon fibers. The morphology and the structures are characterized by a variety of techniques including SEM, TEM, XRD and XPS. Detailed electrochemical...
