Novel solid-state glycine-nitrate combustion for controllable synthesis of hierarchically porous Ni monolith

We demonstrate a novel solid-state glycine-nitrate route for not only the scalable combustion synthesis of hierarchically porous Ni monolith, but also control over impurities, microstructure topography and size. The as-synthesized porous Ni monolith may find instant applications as electrode current collectors, catalyst and catalyst substrates or sensors.
