Abstract
The exchange reaction of methane and deuterium was studied over a series of silica-supported Pt−Ru bimetallic catalysts, whose surface composition was determined by means of O2−CO titration. The stepwise exchange, giving CH3D as the main product, proceeded on each surface Pt atom. The multiple exchange, which formed CD4 directly, proceeded on an ensemble of several Ru atoms.
Abstract
Реакция дейтерийного обмена мэтана изучена на серии биметаллических катализатровов Pt−Ru, нанесенных на SiO2, состав поверхности которых определен с помощью O2−CO титрования. Стуленчатый обмен, дающий CH3D в качэстве основного продукта, протекает на каждом поверхностном атоме Pt. Многократный обмен, приводящий непосредственно к CD4, протекает на группе некоторых атомов Ru.
