Novel visible light-driven photocatalyst of mesoporous tud-1 supported chromium oxide doped titania for phenol photodegradation
Novel visible light driven mesoporous photocatalysts of Technische Universiteit Delft-1 (TUD-1) supported 1 mol% Cr oxide doped TiO2 (Cr-TiO2) were synthesized. Low angle XRD and FTIR results confirmed the amorphous and mesoporous silicate framework of TUD-1 in the materials. The mesostructure was f...
