相比于Rh/In2O3催化剂,Rh/In2O3-ZrO2催化剂显著提高了甲醇选择性以及稳定性。在300 ºC和5 MPa条件下,Rh/In2O3-ZrO2催化剂的甲醇选择性达到了66.5%,甲醇时空收率达到了0.684 gMeOHh-1gcat-1,分别比Rh/In2O3催化剂的高19%和26%。而且,Rh/In2O3-ZrO2催化剂的甲醇时空收率在10小时测试后仅降低了3.5...
Two rhombohedral corundum- type In2O3 (rh-In2O3) nanostructures were successfully prepared through solvothermal synthesis of InOOH precursors combined with post-annealing treatment. One is a unique and monodisperse urchin- like rh-In2O3 with three dimensional structures; another is a small size ...
The N 2O decomposition mechanism on Rh/CeO 2 and Rh/γ-Al 2O 3 catalysts has been studied by pulses of isotopic N 2O and O 2 together with in situ DRIFT, XP and Raman spectroscopies. The higher catalytic activity of Rh/CeO 2 in comparison with Rh/γ-Al 2O 3 is related to the...

According to previous results [11], the catalyst promoted with 2.5 wt%CeO2 on Rh/La2O3–SiO2 showed an increase in the Rh metallic dispersion, but did not improve the stability under reaction conditions. With this background, the objective of this work was to study the effect of low ...
Both Al2O3 and K–Al2O3 were, then, impregnated with aqueous RhCl3·3H2O, dried at 393 K, and in situ reduced in H2 atmosphere to obtain 1 wt.% Rh/Al2O3 and Rh/K–Al2O3 catalysts, respectively. Impacts of the potassium-functionalization on high-temperature behaviour of the Rh ...
