AbstractThe exterior surfaces of the TiO_2 nanotube( TNT) were modified by a silane coupling agent to make nano-Ru selectively deposit on the inner wall. The as prepared catalysts were characterized by transmission electron microscope( TEM),high-resolution transm
Other Abstract采用丙基三甲氧基硅烷(KH570)偶联剂对TiO2纳米管外表面进行疏水改性,通过浸渍法再经氢气热还原法将Ru纳米颗粒原位选择性沉积在TiO2纳米管内。采用TEM、HREM、EDS、HAADF-STEM和紫外可见吸收光谱仪分别对形貌和结构进行表征。结果表明,内嵌于TiO2纳米管的Ru纳米颗粒粒径约为2~3 nm,TiO2纳米管内负载w=2%Ru的光催化性能最好,其光降解罗丹明B的效率大约是单一TiO2纳米管的1.8倍。
