研究目的
Investigating the photocatalytic degradation of brilliant green and fast green dyes using N-S codoped cerium-cobalt oxide bimetal nanoparticles under visible irradiation.
研究成果
The N-S codoped CeCoO3 catalyst showed enhanced photocatalytic activity for the degradation of fast green and brilliant green dyes under visible light. The catalyst is cost-effective and has potential for industrial dye removal applications.
研究不足
The study is limited to the photocatalytic degradation of two specific dyes under controlled laboratory conditions. The scalability and applicability to industrial effluents containing a mixture of dyes and other pollutants were not explored.
1：Experimental Design and Method Selection:
Wet precipitation method was used for the synthesis of cerium-cobalt oxide bimetal nanoparticles. The photocatalytic activity was tested under visible irradiation.
2：Sample Selection and Data Sources:
Aqueous solutions of Ce(NO3)3·6H2O and Co(NO3)2·6H2O were used for synthesis. Brilliant green and fast green dyes were selected for degradation studies.
3：List of Experimental Equipment and Materials:
X-ray diffraction (XRD), scanning electron microscopy (SEM), 200 W tungsten lamp (Philips), solarimeter (SM CEL 201), digital pH meter (Systronics Model 335), spectrophotometer (systronics Model 106).
4：6). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The nanoparticles were synthesized, characterized, and then used in the photocatalytic degradation of dyes under various conditions of pH, light intensity, dye concentration, and dopant percentage.
5：Data Analysis Methods:
The rate of reaction was determined spectrophotometrically by measuring the optical density at regular intervals, and the kinetics were analyzed to follow pseudo-first order.
