Endogenous growth of 2D AlOOH nanosheets on a 3D Al-fiber network via steam-only oxidation in application for forming structured catalysts†
Abstract
We report a facile, green and generalized method of endogenous growth of 2D boehmite nanosheets (ns) on a 3D network using Al-fibers through oxidation reaction between the Al metal and H2O (2Al + 4H2O = 2AlOOH + 3H2). Such Al-fiber@ns-AlOOH composites have substantial potential applications for microfibrous-structured catalysts and catalytic reactors, being verified by several hot-topic reactions such as CO oxidative coupling to dimethyl oxalate.
