Effect of Pd loading on ZrO2 support resulting from pyrolysis of UiO-66: Application to CO oxidation.

Journal of Colloid and Interface Science, 2020
The effect of Pd loading (0.25, 0.5 and 1.0 wt%) and ZrO2 support calcined at diverse temperatures (600, 700 and 800 °C) by pyrolysis of UiO-66 was investigated for CO oxidation in this work, respectively.

MOS devices with tetragonal ZrO2 as gate dielectric formed by annealing ZrO2/Ge/ZrO2 laminate

Microelectronic Engineering, 2011
A Ge-stabilized tetragonal ZrO"2 (t-ZrO"2) film with permittivity (@k) of 36.2 was formed by depositing a ZrO"2/Ge/ZrO"2 laminate and a subsequent annealing at 600^oC, which is a more reliable approach to control the incorporated amount of Ge in ZrO"2. On Si substrates, with thin SiON as an interfacial layer, the SiON/t-ZrO"2 gate stack with equivalent

Enhanced low-temperature performance of CO2 methanation over mesoporous Ni/Al2O3-ZrO2 catalysts

Applied Catalysis B: Environmental, 2019
Converting carbon dioxide to value-added chemicals has been attracted much attention, whereas direct hydrogenation of CO2 to synthetic natural gas (SNG) at a lower temperature remains a big challenge.

Carbon monoxide hydrogenation over ZrO2 and Cu/ZrO2

Journal of the Chemical Society, Chemical Communications, 1993
Sol–gel-derived ZrO2 with a high surface area (> 250 m2 g–1) is found to be very active in CO hydrogenation and unexpectedly produces propan-2-ol with high selectivity; after incorporation of Cu, a methanol synthesis catalyst is produced not only with a higher activity per unit area than Cu/ZnO, but also with an even lower tendency to produce alkanes ...

Cerium-modified Ni-La2O3/ZrO2 for CO2 methanation

Journal of Energy Chemistry, 2020
The key point in CO2 methanation is to improve the activity at low temperature and the stability. For this purpose, a new cerium-modified Ni-La2O3/ZrO2 catalyst was prepared using La1-xCexNiO3/ZrO2 with perovskite phase as the precursor, which was ...
