研究目的
Preparation of C60 nanowhiskers/NiS2 nanocomposites and evaluation of their photocatalytic degradation of organic dyes under ultraviolet light.
研究成果
C60 nanowhiskers/NiS2 nanocomposites were successfully synthesized and demonstrated effective photocatalytic degradation of methylene blue and brilliant green under ultraviolet light. The nanocomposites showed higher efficiency in degrading methylene blue compared to brilliant green.
研究不足
The study focuses on the photocatalytic degradation of specific organic dyes under controlled conditions. The scalability and practical application in diverse environmental conditions were not explored.
1：Experimental Design and Method Selection:
The study involved the synthesis of C60 nanowhiskers using a liquid-liquid interfacial precipitation method and NiS2 nanoparticles through microwave irradiation. The nanocomposites were then prepared and calcined.
2：Sample Selection and Data Sources:
C60 powder, NiCl2·6H2O, and Na2S2O3·5H2O were used as starting materials.
3：List of Experimental Equipment and Materials:
Electric furnace, UV lamp, SEM, TEM, XRD, UV-visible spectrophotometer, and microwave oven were used.
4：Experimental Procedures and Operational Workflow:
Detailed synthesis procedures for C60 nanowhiskers, NiS2 nanoparticles, and their nanocomposites, followed by photocatalytic degradation tests.
5：Data Analysis Methods:
Characterization by XRD and UV-visible spectrophotometry; photocatalytic activity assessed by degradation of dyes.
