Abstract

TiO with different chemical structures are successfully synthesized via a one-step single-mode magnetic microwave (SMMW) assisted process, during where Ti selectively oxidizes in magnetic field under Ar-O mixed atmosphere. The chemical state and band structure of the as-prepared TiO are well-controlled by changing the volume fraction of O (φO) during SMMW synthesis. Ti self-doped TiO (TiO, 0 < x < 2) is synthesized under lower φO, while TiO with specific core/shell structure (TiO core/TiO-TiO shell) is observed under higher φO. The as-synthesized TiO with controlled structures show sufficient light absorption in visible region and quite narrow bandgap (2.05 eV∼), whose value can be also tuned by φO during SMMW synthesis. In addition, the synthesized TiO exhibits highly efficient photocatalytic performance towards the degradation of Rhodamine B under UV and visible light irradiation. The formation mechanism for different structural TiO can be attributed to the specific rapid heating and cooling dynamics induced by SMMW irradiation.

摘要

通过一步单模磁控微波（SMMW）辅助工艺成功合成了具有不同化学结构的TiO，在此过程中，Ti在Ar-O混合气氛下的磁场中选择性氧化。通过在SMMW合成过程中改变O的体积分数（φO），可以很好地控制所制备TiO的化学状态和能带结构。在较低的φO下合成了Ti自掺杂的TiO（TiO，0 < x < 2），而在较高的φO下观察到具有特定核/壳结构（TiO核/TiO-TiO壳）的TiO。合成的具有可控结构的TiO在可见光区域显示出足够的光吸收，并且带隙相当窄（2.05 eV∼），其值在SMMW合成过程中也可以通过φO进行调节。此外，合成的TiO在紫外光和可见光照射下对罗丹明B的降解表现出高效的光催化性能。不同结构TiO的形成机制可归因于SMMW辐照引起的特定快速加热和冷却动力学。
