Study of Co/CeO 2 -γ-Al 2 O 3 catalysts for steam and oxidative reforming of ethanol for hydrogen production

Synthesis of g-C 3 N 4 /CeO 2 nanocomposites with improved catalytic activity on the thermal decomposition of ammonium perchlorate

“…As described in Fig.1 (bottom, a), the diffraction peaks of pure g-C 3 N 4 appearing at 27.4 ° and 13.2 ° corresponded to the (002) and (100) planes, which were in accordance with the characteristic interplanar staking peaks of aromatic systems and the inter-layer structural packing [26]. As [27]. For g-C 3 N 4 /CeO 2 nanocomposites ( Fig.1 (top, c)), the diffraction peaks of both the g-C 3 N 4 and CeO 2 could be observed, confirming the coexistence of g-C 3 N 4 and CeO 2 in the g-C 3 N 4 /CeO 2 nanocomposites.…”

Effects of the addition of CeO2 on the steam reforming of ethanol using novel carbon-Al2O3 and carbon-ZrO2 composite-supported Co catalysts

“… 16 The effect of the addition of Co species to Ni/Al 2 O 3 was confirmed in oxidative SRE where Ni and Co oxides on alumina were reduced at the lower temperature and led to more stable activity and yield of hydrogen. 17 As other catalysts, Co/ZnO–Al 2 O 3 , 18 Co/CeO 2 , 19–21 Co/ZrO 2 , 19,21 Rh/Co/CeO 2 or Al 2 O 3 , 22 K/Co/Al 2 O 3 , 23,24 Co/CaO–Al 2 O 3 , 25 Cu promoted Ni–Co/hydrotalcite 26 for SRE, Co/Al 2 O 3 and Co/CeO 2 Al 2 O 3 for oxidative SRE, 27 and Co–CaO/CeO 2 , ZrO 2 and MgO, 28 CaO–Ni/Al 2 O 3 (ref. 29 ) for sorption enhanced SRE have been reported to have superior activity and selectivity.…”

Ethanol Steam Reforming Followed by Water‐Gas Shift Reaction over Ce‐Ni/MCM‐41 and Fe‐Based Catalysts

“…Owing to the energy demands, the depletion of fossil fuels, and their ecological problems, numerous studies have been performed to discover alternative renewable and environmentally friendly energy sources. Hydrogen is considered a good energy carrier as it has excellent efficiency and its burning product is only water , . However, the problems related to the limited availability, difficult storage, and transport of hydrogen as well as the lack of adequate infrastructure, let hydrogen suffer from serious obstacles toward widespread utilization .…”

“…Ethanol can be extensively utilized because (i) it contains a relatively high number of hydrogen atoms, (ii) it is cheap, (iii) it is safe for humans, (iv) it is easy to preserve, and (v) it is transportable , . However, one of the main reasons for selecting ethanol is that it can be generated in a renewable way from numerous biomass resources (energy plants, residuals of agro‐industries, or forest wastes) and, therefore, shows benefits from the environmental point of view . In theory, hydrogen production from biomass or biomass‐derived liquids can be a natural carbon‐emitting process as all of the carbon dioxide produced can be recycled to plants .…”
