Reactions over Cu/Nb2O5 catalysts promoted with Pd and Ru during hydrogen production from ethanol

Influence of niobium on carbon nanofibres based Cu/ZrO 2 catalysts for liquid phase hydrogenation of CO 2 to methanol

“…TPR peak at the same magnitude of temperature was also recorded by Courtois et al and attributed to reduction of bulk CuO [29]. Reduction of Nb 2 O 5 is generally reported in the temperature range of 800-900 • C in the literature [30][31][32]. Therefore in the current study, all the reduction peaks attribute to the CuO reduction.…”

Ni supported high surface area CeO2–ZrO2 catalysts for hydrogen production from ethanol steam reforming

“…22 Table 1 summarizes the BET surface area, pore volume and pore radius of the CeO 2 -ZrO 2 and x%Ni/CeO 2 -ZrO 2 catalysts, the surface area was found to be 133.5 m 2 g 21 for the CeO 2 -ZrO 2 support, which decreases with increases in Ni loading from 2-20 wt%. This might be a consequence of crystallite rearrangement during metal impregnation, as already reported by Alonso et al, 23 and/or due to the blockage of some pores by NiO particles. 24 These surface areas are higher than those reported by other authors who have prepared ceriazirconia supported nickel catalysts.…”

Catalytic steam reforming of ethanol for hydrogen production: Brief status

“…Despite this, hydrogen technologies are under constant improvement and the use of this gas has the potential to reduce the problems caused by using fossil fuels [5]. Hydrogen can be produced from different feedstocks, such as fossil fuels and renewable raw materials [6,7].…”
