摘要/Abstract

摘要：

为了提高红磷催化剂的光催化性能, 选择剥离膨润土(EB)为载体, 将水热处理后的红磷(HRP)负载在EB上, 制得EB/HRP复合光催化剂, 并通过不同手段对催化剂进行表征。选择罗丹明B为模型污染物, 考察了EB/HRP复合光催化剂的光降解性能。结果表明, 随着EB含量的增加, EB/HRP复合光催化剂的光降解效率呈现先增加后减小的趋势, 当EB的质量分数为9%时, 复合光催化剂(EB₉/HRP)表现出最强的吸附性能和光降解性能, 其降解速率常数k值为0.0641 min^-1, 是HRP的2倍。另外, 经过五次循环光降解实验, EB₉/HRP仍具有较高的光催化活性(96.8%)。因此, EB₉/HRP复合催化剂具有较好的光催化活性和稳定性, 有望成为一种降解污染物的高效而稳定的光催化剂。

Abstract:

The hydrothermally treated red phosphorus (HRP) was dispersed on exfoliated bentonite (EB) supporter to prepare the EB/HRP photocatalyst for improving photocatalytic performance. The as-synthesized samples were characterized by different methods. Rhodamine B was selected as the model pollutant to evaluate the photodegradation property of EB/HRP. Results showed that the photodegradation efficiency of the EB/HRP photocatalyst composite increased with increased EB mass fraction, and decreased after reaching the highest value. When the mass fraction of EB was 9%, the EB₉/HRP photocatalyst composite exhibited the maximum adsorption performance and photodegradation activity. Its degradation rate constant k was 0.0641 min^-1, which was two times that of HRP. In addition, after five cycles of photodegradation experiments, EB₉/HRP still had high photocatalytic activity (96.8%). Therefore, the EB₉/HRP catalyst composite had good photocatalytic activity and stability, which can be an efficient and stable photocatalyst for the degradation of pollutants.

Key words: red phosphorus, bentonite, adsorption enrichment-localized photodegradation, photocatalyst
