Dr. Manchal Chaudhary (Postdoctoral Researcher)

 

Her research interest is the fabrication of titanate nanotubes (TNT) and titania nanoparticles doped with noble metal for CO2 photoreduction. For fabrication of TNTs, P25 has been treated hydrothermally at 180 °C (10 h) in the presence of NaOH and calcined at 400 °C for 2 h. Our goal is to enhance the efficiency of TNTs using noble metal nanoparticles doping over the surface along with the cooperative effect of the available hydroxyl groups (-OH).

氧空缺在一般固態觸媒研究上都擁有很大的關注,過去幾年也有許多先進研究這塊領域,造成眾多研究人員投入氧空缺的研究乃是於氧空缺可以扮演額外能階的提供者、良好的活性點更可以提供表面帶電的特性,綜合以上的結果,控制氧空缺的分布可以使觸媒的活性提供更多的發展性。

利用NaOH在低溫度處理蜂窩觸媒(selective catalyst reduction, SCR),使蜂窩觸媒可以更簡單的被TiO2前驅物附著,處理後的蜂窩觸媒之反應溫度可降低至80-120°C
