英文摘要 | A Cu–Pt nanoparticle catalyst supported on TiO2 nanowires (NWs) was prepared through regenerative counterion exchange–reduction using polyelectrolyte brush as template. Cationic polydimethyl aminoethyl methacrylate brushes were grafted onto TiO2 NWs. Cu–Pt nanocrystals were produced by anionic counterions CuCl42− and PtCl62− bound with the polymer brush through in situ reduction with NaBH4 of high density and low polydispersity. The as-prepared TiO2 NWs/polymer brush/Cu–Pt was characterized by Fourier transform infrared spectroscopy (FT-IR spectrometry), X-ray photoelectron spectroscopy, transmission electron microscopy, and UV–Vis adsorption spectrometry analyses. Results showed that the highly dispersed Cu and Pt nanoparticles were present on the surface of the TiO2 NWs/polymer brush. The resultant TiO2 NWs/polymer brush/Cu–Pt exhibited extremely high catalytic activity and reduced p-nitrophenol at room temperature. |
