Abstract
The disclosure provides a method of dehydrogenating hydrocarbons, such as C2 or C3 hydrocarbons, selectively and efficiently, to provide the corresponding alkylenes. The method is based on a Pt nanolayer catalyst over MXene (Pt/MXene) that shows resistance to coke deposition. The dehydrogenation conditions developed provided about 22% propane conversion and over 90% selectivity toward the desired propylene product, and the catalyst was stable for a 24-hour continuous run. The byproducts were ethane, ethylene, and methane, and only trace amounts of coke deposition over the catalyst were detected. Similar dehydrogenation conditions provided about 18% ethane conversion and over 90% selectivity toward the desired ethylene product. A mass balance of greater than 96% was achieved in each case.
