Nut shell carbon (NSC)-nanotitanium dioxide (TiO(2)) composites were prepared by sol-gel method. Photocatalytic activity on degradation of dye Rhodamine B was studied. X-ray diffraction, field emission scanning electron microscopy, Brunauer-Emmett-Teller surface area, pore size distribution, ultraviolet-vis light absorption spectrum, and photoluminescence spectrum were carried out to characterize the composite catalyst. The results indicated that the photocatalytic activity of NSC-nano-TiO(2) composites was much higher than P25 (Degussa). NSC could greatly absorb the organic substance and oxygen of solution because of its large surface area.
采用溶胶-凝胶法制备了核壳碳（NSC）-纳米二氧化钛（TiO₂）复合材料。研究了其对染料罗丹明B降解的光催化活性。通过X射线衍射、场发射扫描电子显微镜、布鲁诺尔-埃米特-泰勒比表面积、孔径分布、紫外-可见吸收光谱和光致发光光谱对复合催化剂进行了表征。结果表明，NSC-纳米TiO₂复合材料的光催化活性远高于P25（德固赛）。由于NSC具有较大的表面积，它能够大量吸附溶液中的有机物和氧气。
