研究目的
Investigating the photocatalytic degradation of hazardous organic dyes using an ultrasound‐assisted nanoscaled supramolecular coordination polymer as a recyclable catalyst.
研究成果
The nanoscaled supramolecular coordination polymer (nanosized 1′) and its bulk counterpart (SCP 1) demonstrated high efficiency as recyclable heterogeneous catalysts for the photocatalytic degradation of hazardous organic dyes under various conditions. The degradation process is primarily driven by ?OH radicals. The catalysts maintained their structural integrity and catalytic activity over multiple cycles, suggesting potential for practical applications in wastewater treatment.
研究不足
The study is limited to the degradation of specific organic dyes under controlled laboratory conditions. The scalability and applicability to industrial wastewater treatment require further investigation. The recyclability of the catalyst, while demonstrated, may decrease over multiple cycles due to potential toxicity from oxidation products.
1：Experimental Design and Method Selection:
The study involved the synthesis of a nanoscaled supramolecular coordination polymer (nanosized 1′) through a self‐assembly reaction under ambient conditions. The photocatalytic activities of nanosized 1′ and SCP 1 were evaluated under various conditions including ambient, UV‐light irradiation, and ultrasonic conditions.
2：Sample Selection and Data Sources:
Congo Red, Methyl Violet 2B, and Methylene Blue dyes were selected as target pollutants. The catalysts' performance was assessed by monitoring the degradation of these dyes.
3：List of Experimental Equipment and Materials:
Equipment included an ultrasonic bath (Powersonic 405), UV‐light irradiation setup, and analytical instruments for characterization (elemental analysis, FT‐IR, SEM, TEM, XRPD). Materials included K3[Cu(CN)4], hexamethylenetetramine, Me3SnCl, and the organic dyes.
4：Experimental Procedures and Operational Workflow:
The synthesis of nanosized 1′ was performed in an ultrasonic bath. The photocatalytic degradation experiments were conducted under controlled conditions with variations in catalyst amount, dye concentration, H2O2 concentration, and pH. The degradation was monitored by absorbance measurements.
5：Data Analysis Methods:
The degradation efficiency was calculated based on absorbance changes. Kinetic studies were performed under pseudo‐first‐order conditions, and the observed rate constants were determined.
