Novel solid metal–organic self-propagation combustion for controllable synthesis of hierarchically porous metal monoliths

Abstract

We demonstrate a solid glycine–nitrate self-propagation combustion route to fabricate hierarchically porous metallic monoliths. The solidifying temperature (T_s) and environmental gas pressure (P) were effective controlling factors over chemistry, topography and microstructures. This may offer easy scale-up and controllable synthesis of porous metal monoliths for wide applications like electrode current collectors, catalysts, catalyst substrates and sensors.
