CuZnO/Al2O3 is a commercial methanol reforming catalyst (Alfa Aesar) in form of ∼3 mm pellets, containing ∼52 wt% Cu and ∼30 wt% Zn. The PdZnO/Al2O3 catalyst was prepared by one-step coimpregnation [18,56–58]. A concentrated Palladium nitrate solution (∼40 wt% Pd, St...
摘要: Pd/ZnO and Pt/ZnO exhibited anomalously high selectivity for the steam reforming of methanol, when PdZn and PtZn alloys phases were developed. The selectivity decreased over the catalysts having metal phases.关键词: PHOTOCHROMISM SPIROPYRAN DYE LI-AL LAYERED DOUBLE HYDROXIDE CO-INTERCALATE ...

采用Cu原电池反应置换Pd再浸渍负载ZnO的方法,制备了整装式Pd-ZnO/brass-fiber甲醇水蒸气重整催化剂体系.结构催化剂优化组成为:Pd负载量2 wt%,Pd/Zn摩尔比1/3.催化剂的最佳焙烧温度和还原温度分别为350 ℃和450 ℃.该催化剂具有高的C02选择性,以CH30H/H20=1/1.2(mol/mol)的混合物为原料,在WHSV=5.4h-1的...
the magnitude of optical rotation exhibits a noticeable difference despite the identical sign. This difference could be explained by the following two factors. First, we found that a didehydroparvistemonine sample could not dissolve well in methanol but was completely dissolved in CHCl3. Consequently...
Moreover, PdCu and PdZn bimetallic phases have also been reported as active sites for methanol synthesis [27], [28]. The complexity of surface sites (Pd, Cu, PdCu, PdZn, CuZn, et al.) would make it rather difficult to identify the real active sites in the Pd modified CuZn catalysts....
Wang and co-workers [31] have developed an novel catalyst named Cu/AC-600, which exhibits an catalytic activity toward a MMP yield of 93.2% at 120 °C, 2 MPa H2 for 5 h. Similarly, Kim et al. [25] prepared a ZnO/Co@N-CNTs by calcination of bimetallic Zn/Co zeolitic imidazolate ...
