由于其能带位置和独特的晶体结构，CsTaWO 6是一个非常有趣的模型系统，用于研究形态对光催化制氢和分解水性能的影响。本文采用水热法合成了8-30 nm的纯相和单晶CsTaWO_6纳米粒子。通过调节合成中碱的量来控制纳米颗粒的尺寸。采用不同粒径的纳米粒子进行光催化水/甲醇制氢反应。最佳的颗粒尺寸被认为是约13 nm的最大气体析出活性。
Due to its band positions and unique crystal structure, CsTaWO6is a very interesting model system for the investigation of morphological influences on the performance in photocatalytic Hydrogen generation and water splitting. Here we present the synthesis of phase-pure and single crystal CsTaWO6nanoparticles in the range of 8–30 nmviahydrothermal synthesis. The nanoparticle size was controlled by adjusting the amount of base in the synthesis. Nanoparticles of different sizes were used to perform photocatalytic Hydrogen generation from water/methanol. The optimum particle size was found to be around 13 nm with regard to maximum gas evolution activity.
