为了降低商业可见光催化剂的成本，采用自组装技术制备了钛偶联氮包埋鸡毛生物炭基催化剂。将含钛交联剂与水解后的含氮鸡毛共混制备了含钛交联剂。采用X射线衍射、傅里叶变换红外光谱、扫描电子显微镜、透射电子显微镜、能量色散X射线光谱、X射线光电子能谱、拉曼光谱、比表面积分析和紫外-可见吸收光谱对合成材料进行了表征。在TiN上观察到多层氧化石墨烯样结构，其类似于TiO 2-氧化石墨烯材料。在可见光照射下，240 min后，TiNCs对罗丹明B的降解率达到90.91%。溶液的相应TOC下降了56.26%。每一片TiN都由多层氧化石墨烯状骨架构成，均匀地散布着TiO 2纳米颗粒。并对一些机理进行了分析。成本分析表明，TiN纳米材料具有良好的工业化前景。
In order to reduce the cost of commercial visible-light photocatalyst, a self-assembly strategy was deployed in producing a Ti-coupled N-embedded chicken feather biochar based catalyst (TINCs). The TINCs were manufactured by blending Ti-contained cross-link agent with hydrolyzed N-embedded chicken feather. These synthesis materials were well characterized with X-ray diffraction, Fourier transform infrared, Scanning electron microscopy, Transmission electron microscope, Energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, Surface area analysis and UV–vis absorption spectra. There were multilayered graphene oxide-like structures observed on TINCs, which were similar to the TiO2-graphene oxide material. Correspondingly, the TINCs had presented a 90.91% degradation rate of Rhodamine B under visible-light after 240 min. The corresponding TOC of the solution had dropped by 56.26%. Every slice of TINCs was constituted by multilayered graphene oxide-like framework, interspersing with TiO2nanoparticles uniformly. Some mechanisms were also analyzed. The cost analysis investigated that TINCs was promising in industrialization.
