Abstract
The interaction of ethylene and propylene with the surface of MoS2 has been investigated by means of a thermodesorption technique. Two types of adsorption sites on the surface of MoS2 have been detected. From one type of sites the olefin is desorbed without changes, whereas from the other in the form of conversion products. Propylene desorption has been shown to be accompanied with carbon deposition on the active sites.
Abstract
Методом термодесорбции изучено взаимодействие этилена и пропилена с поверхностью MoS2. Установлено существование на поверхности сульфида молибдена двух типов адсорбционных центров, с одного из которых олефин десорбируется в неизменном виде, а с другогов виде продуктов его превращения. Показано, что десорбция пропилена сопровождается отложением углерода на активных центрах.
