Progress in catalysis is driven by society's needs. The development of new electrocatalysts to make renewable and clean fuels from abundant and easily accessible resources is among the most challenging and demanding tasks for today's scientist and engineers. The electrochemical splitting of water into hydrogen and oxygen has been known for over 200 years, but in the last decade and motivated by the perspective of solar hydrogen production, new catalysts made of earth-abundant materials have emerged. Here we present an overview of recent developments of the non-noble metal catalysts for electrochemical hydrogen evolution reaction (HER). Emphasis is given to the nanostructuring of industrially relevant hydrotreating catalysts as potential HER electrocatalysts. The new syntheses and nanostructuring approaches might pave the way to future developments of highly efficient catalysts for energy conversion.

“…However, Pt remains to be an expensive metal and suffers from a shortage in global supply. Considerable attempts have been made recently to develop transition metal chalcogenides, 1-4 complexes 5 and metal carbides [6][7][8][9][10][11] for the purpose of replacing the Pt group metals. Among these catalysts molybdenum sulde-based hydrogen evolution reaction (HER) catalysts have been investigated extensively.…”

“…Ordinarily, the smaller the particle size the bigger the specific surface area is, and so the catalytic activity of tungsten carbide is, because the catalytic activity of tungsten carbide is a function of the surface area only [21] . The specific surface area of MWCNT-WC composites was much larger than the WC micropheres [7] .…”

Tungsten trioxide micropheres were prepared by spray pyrolysis, and tungsten carbide microspheres were produced by spray pyrolysis-low temperature reduction and carbonization technology. Multi-walled carbon nanotube-tungsten carbide composites were prepared by the continuous reduction and carbonization process using multi-walled carbon nanotubes (MWCNTs) and WO 3 precursor by molecular level mixing and calcination. The morphology and structure of the samples were characterized by scanning electron microscope and transmission electron microscope. Furthermore, the crystal phase was identified by X-ray diffraction. The electrocatalytic activity of the sample was analyzed by means of methanol oxidation. Tungsten carbide microspheres were catalytic active for methanol oxidation reaction. Nevertheless tungsten trioxide microspheres and multi-walled carbon nanotube-tungsten carbide composites were not catalytic active for methanol oxidation reaction. These results indicate that tungsten carbide micropheres are promising catalyst for methanol oxidation.
