Ni(OH)2 with a high specific surface area was synthesized by a facile fast precipitation method.Porous nano-NiO was obtained by calcining Ni(OH)2 at 300 ℃.The NiO sample possesses a fine porous distribution at ar...
Porous metallic nickel has been synthesized using SiO2 opal as template. The template was prepared by self-assembled sedimentation of monodispersed SiO2 spheres. The metallic nickel precursor was impregnated into the ...
Nanoporous gamma aluminum oxide (γ-Al2O3) was synthesized by solvothermal method in the presence of AlCl·36H2O, urea and alcohol. The calcined sample was characterized by XRD, FTIR, TEM, and Nitrogen ad- sorption-de...
