“…A majority of these studies were focused on the application of WC-based materials as HOR anode catalysts. [228][229][230][231][232][233] In these studies, high HOR activity of WC materials was observed in a PEM fuel cell setup, 233 displaying a current density of 0.9 A cm À2 at a cell voltage of $0.14 V, temperature of 80 C and backpressure of 3 atm. This performance was still inferior to that of commercial Pt/C.…”

“…Tungsten carbide (WC) as catalyst for electron-transfer reactions has been extensively investigated in various applications, such as, hydrogenolysis and isomerization reactions, fuel cells, hydrogen evolution and oxygen reduction (Palanker et al 1976;Rosenbaum et al 2006), because it exhibits catalytic properties similar to those of noble metals (Levy and Boudart 1973) .…”

“…952–954 Numerous publications have appeared confirming the ability of various transition metal carbides to act as catalysts for the heterogeneous catalysis of a wide variety of reactions. 955–960 To the authors' knowledge, HER electrocatalysis on carbides was first investigated in 1975 by Sokolsky et al 955 who carried out polarisation measurements in 1.0 N acids (H 3 PO 4 , HCl, H 2 SO 4 ): a HER overpotential of 250 mV was measured for j = 1.8 mA cm −2 . Over works followed for tungsten carbide electrodes 961–965 but either they lack a detailed examination of the electrode composition or an identification of the catalytically-active phase 961 or the basic results were later not reproduced by others.…”
