Nitrogen-doped Titanium Dioxide(N-doped TiO2)for Visible Light Photocatalysis.pdf

1、Mesoporous nitrogen-doped titania(TON)anatase phase photocatalysts were successfully prepared using sol-gel and solvent evaporation induced self-assembly(SEISA)methods.Dodecylamine(DDA)and diethylenetriamine(DETA)were us

2、ed as surfactants for endowing mesoporosity,complexing agents,base catalysts for polymerizing titania source(titanium isopropoxide),and sources for nitrogen doping.It was found that the titania source and the amount of D

3、DA and DETA influenced strongly the textural[specific surface area(SBET),pore volume,and pore size],optical[UV-Vis absorbance and band gap energy(Eg)],morpholoical properties,and photocatalytic activity of TON photocatal
