M-Al (M = Mg, Ni, Co, Zn) hydrotalcite was synthesized on the surface of γ-Al2O3 carrier, and calcined to corresponding carrier. Then, A series Cu-Ce/M-Al catalysts were prepared by sequential dip method. The characterized means XRD, BET, H2-TPR, XPS, which investigated effects different divalent metals M structure, properties, catalytic performance derived for hydrogen production from methanol steam reforming. main reasons lie in difference dispersion, reduction temperature, content oxygen...

A catalytic hypervalent iodine oxidation of p-dialkoxybenzenes using 4-iodophenoxyacetic acid (1) and 2KHSO5 x KHSO4 K2SO4 (Oxone) was developed. Reaction (2) with a amount 1 in the presence Oxone as co-oxidant 2,2,2-trifluoroethanol-water (1 : 2) gave corresponding p-quinones (3) excellent yields without purification. This procedure applied to synthesis blattellaquinone (9), sex pheromone German cockroach, Blattella germanica.
A catalytic hypervalent iodine oxidation of p-alkoxyphenols using 4-iodophenoxyacetic acid (1a) and Oxone® was developed. Reaction p-alkoxyphenol (2) with a amount 1a in the presence as co-oxidant 2,2,2-trifluoroethanol–water (1 : 2) gave corresponding p-quinone (3) excellent yield without special operation. The substituent effect on iodobenzene ring observed; p-alkoxy is most effective, series following approximate order p-RO>p-Me, o-MeO, m-MeO>H>o-CO2H. And remarkable solvent effects were observed.
Chemical looping represents a novel approach for generating light olefins in which thermal cracking or catalytic dehydrogenation is coupled with selective hydrogen combustion (SHC) by metal oxide redox catalyst, enables autothermal operation, increased per‐pass conversion, and greater‐than‐equilibrium yields. Recent studies indicate that Na 2 WO 4 ‐promoted perovskite oxides are effective catalysts high olefin selectivity. Herein, kinetic parameters, rates, reaction models the reduction of...
Abstract A new method for the synthesis of imidazo[1,5‐α]pyridines, one most important N‐heterocyclic compounds due to their wide application, was reported in this study. Specifically, using I 2 as a non‐metal catalyst and TBPB an oxidant can efficiently facilitate avoid use metal catalyst. The reaction between ethyl ( E )‐2‐(benzylideneamino)acetate pyridine represents unprecedented 1,3‐diolar cycloaddition highly straightforward process with great value.
Brownmillerite-structured Ca2MnAlO5+δ has demonstrated excellent oxygen storage capacity that can be used for chemical looping air separation (CLAS), a potentially efficient approach to produce high-purity from air. To effectively utilize this material as an sorbent in CLAS, it is necessary comprehensively understand its thermodynamic properties and the structure–performance relationships operating range of interest. In work, nonstoichiometry (δ) was systematically measured by...
