- 摘要：
- We present a facial one-pot synthesis method for fabrication of mesoporous anatase-TiO2(B) mixed-phase nanowires (TNWs) decorated with sulfur and Fe2O3 nanoparticles (NPs). Through one-pot calcination, control of morphology and crystal phase for TNWs was easily achieved. After calcined at 773 K, mixed-phase heterostructured TNWs with mesoporous structure and high surface area were obtained. This can not only lead ultrafine NPs well-disperse in porous matrix, but also greatly enhance interfacial separation and transfer of photo-induced charges between various planes. Moreover, sulfur doping improved acid/light properties of solid and brought more orbital-overlapping between active sites and H2O2. The prepared S-Fe2O3/anatase-TiO2(B) TNWs had excellent catalytic ability in visible-light assisted Fenton oxidation at neutral pH, which was attributed to the synergistic effect of sulfur species, NPs and TNWs. The progresses are valuable in developing highly efficient and green heterogeneous catalysts.
