英文摘要: Abstract(#br)With special focus of the effect of dopant concentration on physicochemical properties, a series of visible light active nitrogen doped titania (N/TiO 2 ) nanomaterials were successfully synthesized via sol-gel method of titanium butoxide in the presence of benign N dopant guanidium chloride. The resulting anatase/rutile (A/R) mixed phase materials were subjected to different characterization techniques, and their photocatalytic performance was evaluated against methylene blue (MB) dye under visible light irradiation. The results confirmed that the N was effectively doped in interstitial sites (7.2 atomic%) with Ti-N-O linkage, and the N/Ti mol ratio significantly dictated the physicochemical properties, and photodegradation of the photocatalysts. Notably, the mesoporous...
