以钛酸四丁酯(TBT)和 AgNO3为原料，采用溶剂热法一步合成了 Ag/TiO2核壳结构纳米纤维和纳米颗粒，并利用 SEM、TEM、XRD 等详细表征了样品的结构和组成。AgNO3添加量、水热反应温度、分散剂聚丙烯酸(PAA)等对产物的形貌、结构和晶型有较大影响，并进一步研究了形貌、结构和组成对光催化性能的影响，分析了造成影响的机制。

Ag/TiO2 core-shell nanofibers and nanoparticles were synthesized via one-step solvothermal method using tetrabutyltitanate (TBT)and AgNO3 as precursors.The structure and composition of these samples were characterized by SEM,TEM and XRD.The content of AgNO3 ,reaction temperature and dispersant agent polyacrylic acid (PAA)had an important influence on the morphology,structure and crystalline of the Ag/TiO2 composite materials.The effect of these factors on the photocatalytic activities was investigated and the re-action mechanism was proposed.
