Abstract
|
The
efficient use of natural gas will require catalysts that can activate the
first C–H bond of methane while suppressing complete dehydrogenation and
avoiding overoxidation. Authors report that single iron sites embedded in a
silica matrix enable direct, nonoxidative conversion of methane, exclusively
to ethylene and aromatics.
The reaction is initiated by catalytic generation of methyl radicals, followed by a series of gas-phase reactions. The absence of adjacent iron sites prevents catalytic C-C coupling, further oligomerization, and coke deposition. |
