“…-- 10 Klein [32] has performed the H-TiCS calculation and found essentially no chemisorptive bond. This agrees with previously cited work [7,24] which shows no chemisorption of hydrogen on stoichiometric TiC. Two predictions, however, can be made for non-stoichiometric TiC from these cluster models.…”

“…Tungsten carbide is a lower-cost, corrosion-resistant material and has been found to possess activity for hydrogen oxidation approaching that of platinum [2,[6][7][8] and has the same two-step + reaction for hydrogen oxidation: H2 + 2H + 2H + 2e-, with ads the first step, the Tafel reaction, being rate determining. : [2,3] Tungsten carbide is not poisoned at any level of carbon monoxide, the United States, [18,19] have worked toward the development of tungsten carbide as a fuel cell catalyst.…”

“…Hydrogen evolution on smooth tungsten carbide in 1 M H 2 SO 4 obeys the Tafel equation [27,28]; a coefficient b of 135 mV at 22°C has been reported [27], whereas the same coefficient was 65 mV at 50°C [28].…”

“…An analysis of literature data [21][22][23][24][25][26][27][28] showed that the differences between the data obtained by different authors could be connected not only with the different methods of preparation and dispersity of the carbides, but also with features of the method used for the measurement of the log i ) g curves.…”
