Abstract. A set of nanocrystalline cobalt oxide (Co3O4)-based catalysts have been prepared by means of an innovative soft reactive grinding (SRG) procedure. The catalysts exhibited excellent activities and high stabilities for propane catalytic combustion. Complete conversion has been achieved at reaction temperatures as low as 240 ◦C. Comparing with the highly active Co3O4 catalysts in t…
Abstract. Dehydrogenation of propane to propylene in the presence or absence of carbon dioxide was performed over a series of mixed GaxAl10−xO15 oxides (with x varying from 0 to 10) synthesized through an alcoholic coprecipitation pathway. Among the various compositions of GaxAl10−xO15, the maximum activity was observed for x = 8. Whereas the same tendency was observed for the specific …
Abstract. Positive and negative micropatterned copper sulfide thin films were successfully fabricated through chemical bath deposition methods. The thin films were deposited on patterned Si substrates with two different self-assembled monolayers (SAMs), i.e., NH2/CH3 and NH2/OH terminated silane, respectively. Under an optimal depositing condition, the copper sulfide thin films were selecti…
Abstract Oxidative bromination of methane, mediated by HBr/H2O (solution), provides an original route for the production of oxygenates and gasoline directly from natural gas. However, the reported catalysts for this reaction all involved noble metals. From the consideration of replacing noble metal catalysts with cheaper oxides, various silica-supported oxide catalysts were surveyed. It was…
