摘 要:金屬卟啉是一類(lèi)具有良好光敏性的大環(huán)芳香化合物。以cis-ortho-雙捆扎的雙弓型銅卟啉1-Cu至4-Cu為光催化劑,以平面銅卟啉TPP-Cu為參照,在異相和可見(jiàn)光下催化降解甲基橙。結果表明銅卟啉光催化性能與大環(huán)扭曲有正向相關(guān)性。采用動(dòng)態(tài)紫外-可見(jiàn)吸收光譜手段跟蹤大環(huán)扭曲對銅卟啉光催化性能的影響。 |

Abstract:Metalloporphyrin is a macrocyclic conjugated aromatic compound with high performance of photosensitivity. The double-bowed copper porphyrins 1-Cu to 4-Cu cis-ortho-distrapped were used as photocatalysts to catalyze the degradation of methyl orange under visible light and heterogeneous condition, and the planar copper porphyrin TPP-Cu was used as a reference. The results showed a positive correlation between the photocatalytic performance of copper porphyrins and the macrocyclic distortion. The effect of macrocyclic distortion on the photocatalytic performance of copper porphyrins was tracked by means of dynamic UV-vis absorption spectroscopy. |
Key words:photocatalysis; metalloporphyrin; molecular conformation; methyl orange |
