Abstract
Strontium hydroxyapatite of various Sr/P ratios catalyzes oxidative dehydrogenation of methane to carbon oxides and hydrogen at a reaction temperature of 600°C. Although the selectivities are essentially independent of the composition of the catalyst, the activity decreases with decreasing concentration of strontium. The relatively high ratio of H2/CO produced cannot be rationalized either through the oxidation of methanol on the catalyst or the water gas shift reaction, but appears to result primarily from the direct oxidation of methane, with the reaction to produce CO2 and H2 proceeding at a rate approximately twice that to CO. New active sites associated with strontium appear to be responsible for the catalytic properties of the hydroxyapatite.
期刊介绍：
Journal of Molecular Catalysis (China) is a bimonthly journal, founded in 1987. It is a bimonthly journal, founded in 1987, sponsored by Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, under the supervision of Chinese Academy of Sciences, and published by Science Publishing House, which is a scholarly journal openly circulated both at home and abroad. The journal mainly reports the latest progress and research results on molecular catalysis. It contains academic papers, research briefs, research reports and progress reviews. The content focuses on coordination catalysis, enzyme catalysis, light-ribbed catalysis, stereochemistry in catalysis, catalytic reaction mechanism and kinetics, the study of catalyst surface states and the application of quantum chemistry in catalysis. We also provide contributions on the activation, deactivation and regeneration of homogeneous catalysts, solidified homogeneous catalysts and solidified enzyme catalysts in industrial catalytic processes, as well as on the optimisation and characterisation of catalysts for new catalytic processes.
The main target readers are scientists and postgraduates working in catalysis in research institutes, industrial and mining enterprises, as well as teachers and students of chemistry and chemical engineering departments in colleges and universities. Contributions from related professionals are welcome.
