采用水热热压法对铂负载钛酸盐纳米管进行形貌控制，以提高其光催化性能。采用HHP技术在不经H2还原的条件下成功制备了Pt-TiO_2负载钛酸盐纳米管。大体积的Pt-Pd负载的钛酸盐纳米管具有致密的微观结构，明显尖锐的中孔分布，和高的Brunauer-Emmett-Teller（BET）表面积。此外，在紫外光照射下，大体积的Pt-TiO_2负载的钛酸盐纳米管表现出光催化降解2-丙醇水溶液的活性。
Morphologic control of Pt supported titanate nanotubes was attempted by the hydrothermal hot-pressing (HHP) technique in order to improve the handleability as a photocatalyst. The bulk of Pt-nanocrystal supported titanate nanotubes was successfully fabricated without the H2reduction process by applying the HHP technique. The bulky Pt-nanocrystal supported titanate nanotubes possessed dense microstructures, significantly sharp distributions of mesopores, and high Brunauer–Emmett–Teller (BET) surface area. Furthermore, the bulky Pt-nanocrystal supported titanate nanotubes showed the photocatalytic degradation activities of 2-propanol aqueous solution under UV-light irradiation.
