研究目的
Investigating the synthesis and photocatalytic activity of nano-Bi2MoO6/calcined mussel shell composite for the degradation of Methylene blue (MB) dye under visible-light irradiation.
研究成果
The nano-Bi2MoO6/calcined mussel shell composite, especially with a mass ratio of 0.7/1, exhibited superior photocatalytic activity for MB degradation under visible light, demonstrating good stability and reusability. This composite holds promise for environmental remediation applications.
研究不足
The study focuses on the degradation of MB dye under specific conditions; the applicability to other pollutants or under different environmental conditions was not explored. The scalability and cost-effectiveness of the synthesis method for industrial applications were not discussed.
1：Experimental Design and Method Selection:
The study employed a solvothermal method to synthesize nano-Bi2MoO6/calcined mussel shell composite.
2：Sample Selection and Data Sources:
Mussel shells were collected from Shengsi, Zhejiang, China, and chemicals were purchased from Sinopharm Chemical Reagent Co., Ltd.
3：List of Experimental Equipment and Materials:
Equipment included a tubular furnace, Teflon-lined stainless steel autoclave, and characterization tools like SEM, FTIR, XRD, and UV-vis DRS.
4：Experimental Procedures and Operational Workflow:
The mussel shells were calcined, ground, and mixed with Bi2MoO6 precursors, then subjected to solvothermal synthesis.
5：Data Analysis Methods:
The photocatalytic activity was evaluated by degrading MB under visible-light irradiation, and the degradation efficiency was analyzed.
