For improving stability and efficiency of noble metal nanomaterials, a straightforward one-step method was developed to synthesize Au–SiO2 composite nanospheres. Monodisperse hybrid silica nanospheres that had anilino-methyl on the surfaces were prepared first. The as-prepared hybrid silica nanospheres were then used to obtain Au nanocrystal through the redox reaction of HAuCl4 and anilino-methyl...
