利用多壁碳纳米管（MWCNT）上的氨基与制备的BiOBr表面残留的羧基或羟基之间的反应，通过酰胺键或氢键的界面连接，成功地设计了MWCNT/BiOBr复合材料。在保持与纯BiOBr相似的形貌、尺寸和结晶度的情况下，2 wt.%的BiOBr的光催化性能明显增强，MWCNT/BiOBr复合材料可以归因于MWCNT通过界面共价键有效地捕获和传输光生电子。
MWCNT/BiOBr composite was successfully designed through interfacial linkage of amide bonds or hydrogen bonds by utilizing the reaction between amino groups of MWCNT and residual carboxyl or hydroxyl groups on the surface of prepared BiOBr. Retaining similar morphology, size and crystallinity with pure BiOBr, the obviously enhanced photocatalytic performance of the 2 wt.% MWCNT/BiOBr composite can be attributed to effective capture and transport of photo-generated electrons by MWCNT through the interfacial covalent bond.
