Structural formation of Ni/SiO 2 in a solution exchange method, where Ni was supported on silica by exchanging the solution in wet silica gel derived from tetraethoxysilane under acidic conditions, and its catalytic property were investigated. In the preparation of Ni/SiO 2 , the dispersion of Ni is largely dominated by aggregation in drying, while mesopore structure in the silica...
