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

Abstract

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.

This paper has been withdrawn by the author due to 1. a crucial data error in Fig 2 the propagating velocity for gel combustion was wrongly displayed for solid-state combustion. 2. important XRD structure information for combustion precursors is supplemented in new version with IR spectroscopy to establish that the precursors were new from the GN mechanical mixture and GN reacted with each other to form molecular-level mixed precursors
