采用钛酸四正丁酯为前驱体低温制备N掺杂TiO2纳米溶胶,并利用紫外-可见光谱对其分子结构及光学性能进行了表征研究.%Nitrogen doped titania nano[ J ] materials have good Visible light catalytic activity. However, reported preparation in the literature mostly were under the harsh experimental conditions, the process were complicated and required expensive reagents, moreover, the amount of nitrogen -doped was low, All of these defects made the synthesis method has been extremely limited, This article using tetrabutyl titanate as precursor,prepared nitrogen doped titania nano- sol materials at low temperature, besides, using UV - Vis characterized its molecular structure and optical properties.
