A chemical method for in situ synthesis of copper nanoparticles on SBA-16 silica spheres under ambient conditions has been reported. The silica support has been introduced into copper precursor solution before chemical reduction. Metal ions diffuse into mesopores (pore diameter 5–7nm) of silica where in situ reduction by hydrazine leads to formation of nanoparticles. These mesopores act as nanoreactor...
