Dendritic nanospheres with unique three dimension (3D) center-radial channels possess excellent specific surface area and pore volume. Objects can be loaded into the nanochannels of dendritic nanospheres, developing novel carrier, delivery vehicle, or reaction platform. In the work, a novel kind of highly stable multifunctional composite material has been explored for the first time, i.e., dendritic mesoporous silica titania nanospheres (DMSTNs) supported gold (Au) nanoparticles. Even though DMSTNs have suffered series of chemical reactions and modifications, 3D center-radial textures are still unchanged. Anatase TiO2 and Au nanoparticles have been successfully decorated onto the channels. The as-prepared catalysts exhibit more outstanding multipurpose catalytic performances than those of a contrast sample, i.e., dendritic mesoporous silica nanospheres (DMSNs) supported gold (Au) nanoparticles. Under simulated sunlight for splitting water, the amount of produced H2 and the corresponding rate are 210.01 mmol.g-1, ca. ten-folds of the contrast sample. Without light irradiation, the apparent kinetic constant of p-nitrophenol reduction by our catalyst is 2.150×10-3 s-1, being about nineteen times than that of the reference (0.111×10-3 s-1).
