Rh/MgO/Ce0.5Zr0.5O2 supported catalyst for autothermal reforming of methane: The effects of ceria–zirconia doping

Partial oxidation of palm fatty acids over Ce‐ZrO2: Roles of catalyst surface area, lattice oxygen capacity and mobility

“…The good reactivity was found to be closely related with the high OSC and lattice oxygen mobility of this synthesized catalyst, according to the reduction/oxidation measurement and 18 O/ 16 O isotope exchange study. It was also revealed that this nanoscale Ce-ZrO 2 can be efficiently used as the preoxidative catalyst to initially convert PFAD to light hydrocarbons, from which the latter reforms with steam in the presence of Ni-based catalyst to complete the hydrocarbon conversion and maximize H 2 yield.…”

“…It is noted that the average catalyst particle sizes were estimated by the nanosizer and the particle size analyzer. To investigate the OSC and lattice oxygen mobility of synthesized catalysts, the reduction/oxidation measurement and 18 O/ 16 O isotope exchange study were applied; details of these studies are described in Section ''reactivity of Ce-ZrO 2 toward partial oxidation of PFAD.'' It is noted that, for comparison, Ni/Ce-ZrO 2 (with 5 wt % Ni) was also tested for steam reforming reaction in this work.…”

“…The sample (200 mg) was placed in the quartz reactor and thermally treated under the flow of high-purity helium (99.995%) at the desired temperatures for 1 h. Then, 18 O 2 (in helium as carrier gas) was multiple times pulsed to the system and the outlet gases were monitored by O at 600 C for this Ce-ZrO 2 with Ce/Zr of 3/1, 1/1, and 1/3 were 11 and 7%, 9 and 5%, and 6 and 2%, respectively.…”

Thermally Stable CeO2–ZrO2–La2O3 Ternary Oxides Prepared by Deposition–Precipitation as Support of Rh Catalyst for Catalytic Reduction of NO by CO

“…Related to the catalyst performance, it is clear that larger surface area, pore size and volume in the Rh/D-960 catalyst are beneficial to NO and CO conversion due to its enhanced internal diffusion [38]. Although OSC can partially contribute to the conversion, one cannot conclude that the higher the OSC, the better the catalytic activity for the reduction of NO by CO is.…”

Monolith and foam catalysts performances in ATR of liquid and gaseous fuels

“…Since the ATR process may be considered as the synthesis of SR and POX [22], the catalyst must ensure simultaneously a high selectivity towards these two reactions, inhibiting other unwanted, such as hydrocarbon cracking. Several studies have demonstrated that nickel [23][24][25] as well as noble metals (Pt, Rh, Ru) [26][27][28] supported on Al 2 O 3 , CeO 2 or ZrO 2 show good activity toward reforming reactions [29][30][31][32][33]; improvements in stability and selectivity are achieved from bimetallic catalytic systems [34]. Great attention must be also devoted to the catalyst structure (e.g.…”
