利用X射线衍射分析(XRD),比表面积分析(BET),透射电镜分析(TEM),紫外可见光分析(UV-vis)等对神府煤掺杂的二氧化钛(12%SFC-TiO2)光催化剂进行了表征,并与自制的二氧化钛(TiO2),氮掺杂二氧化钛(15%N-TiO2),铁氮共掺杂二氧化钛(0.6%Fe-15%N-TiO2)和钴掺杂二氧化钛(1.5%Co-TiO2)催化剂进行了比较.结果发现,神府煤掺杂的光催化剂为锐钛型纳米颗粒,其光学活性要高于二氧化钛、氮掺杂二氧化钛和铁氮共掺杂二氧化钛;将其应用于降解大港减渣(DVR),结果表明,在经该催化剂光催化氧化后的DVR产物中,含氧化合物相对含量高达92.43%,正构烷烃含量降为2.30%;在氧化产物中的最长碳链(C26)远小于原样中的最长碳链(C36),说明SFC-TiO2光催化氧化降解大港减渣是有效的.
The Shenfu coal-doped titanium dioxide (12% SFC-TiO2) photocatalyst was characterized by X-ray diffraction (XRD), BET, TEM, UV- And characterized with self-made TiO 2, N-doped TiO 2, Fe-N doped TiO 2 and Co-doped TiO 2 (1.5% Co -TiO2) catalyst was compared.The results show that the Shenfu coal doped photocatalyst anatase nanoparticles, its optical activity is higher than that of titanium dioxide, nitrogen-doped titanium dioxide and iron-nitrogen co-doped titanium dioxide; its application to Degradation of Dagang Dregs (DVR) showed that the relative content of oxygenated compounds was 92.43% and the n-alkane content was reduced to 2.30% after the photocatalytic oxidation of DVR. The longest carbon in the oxidation products The chain (C26) is much smaller than the longest carbon chain (C36) in the original sample, indicating that SFC-TiO2 photocatalytic oxidation of Dagang slag reduction is effective.
