除锐钛矿型、卢布型和板钛矿型外，TiO2(B)是典型的TiO2晶体结构。本工作制备了Pd修饰的一维TiO(2)(B)。所得Pd/TiO2(B)用于光热催化苯甲醇氧化。 Pd纳米粒子的（111）面和TiO2（B）的（003）面之间形成了良好匹配的异质结构接触边界，这可能有利于界面光生电子转移。 Pd/TiO2(B)催化剂表现出增强的光热催化活性，这归因于Pd、TiO2(B)及其良好匹配的异质结的协同效应，以及热催化和光催化之间的协同作用。
TiO2(B) is typical crystal structure for TiO2, besides anatase, ruble and brookite. In this work, one-dimensionalTiO(2)(B) modified by Pd were prepared. The obtained Pd/TiO2(B) was used for photo-thermocatalytic benzyl alcohol oxidation. Well-matched heterostructure contact boundary between (111) planes of Pd nanoparticles and (003) planes of TiO2(B) was formed, which might facilitate interfacial photo-generated electrons transfer. The Pd/TiO2(B) catalyst exhibited enhanced the photo-thermocatalytic activity, attributed tothe synergistic effect of Pd, TiO2(B) and their well-matched heterojunction, and also the synergism between the thermocatalysis and photocatalysis.
