We herein report successful syntheses of both nickel cobalt sulfide (NCS) and its composite
with zeolite (NCS@Z) using a solvothermal method. Techniques such as EDX analysis, SEM, and
molar ratio determination were used for product characterization. The incorporation of NCS significantly changed the surface roughness and active sites of the zeolite, improving the efficiency
of methylene blue degradation and its reusability, especially under UV irradiation. In comparing
the pseudo-first order rates, the highest degradation efficiency of methylene blue was achieved
with NCS-2@Z, having a degradation extent of 91.07% under UV irradiation. This environmentally
friendly approach offers a promising solution for the remediation of methylene blue contamination
in various industries.
