homogeneous Fe-Mo/MgO catalyst. Ambient effects (air, Ar, and H2) on thermal decomposition of the citrate precursor have been systematically investigated to fabricate an Fe-Mo/MgO catalyst. Severe agglomeration of metal catalyst was observed under thermal decomposition of citrate precursor in air atmo- sphere. Ar/H2 atmosphere effectively restricted agglomeration of bimetallic catalyst and for-... -

4 was introduced into the reaction tube at ambient pressure. To obtain the GFs, before etching away the nickel skeleton with a hot HCl (or FeCl 3) solution, a thin layer of poly(methyl methacrylate) (PMMA) was deposited on the sur- face of the graphene flms. The PMMA support prevented the graphene network from collapsing during nickel etching, as il- lustrated in Fig. 3. The GF then copies and... Porous materials play a vital role in science and technology. The ability to control their pore structures at the atomic, molecular, and nanometer scales enable interactions with atoms, ions and molecules to occur throughout the bulk of the material, for practical applications. Three-dimensional (3D) porous carbon-based materials (e.g., graphene aerogels/hydrogels, sponges and foams) made of graphene or graphene oxide-based networks have attracted considerable attention because they offer low... -
