Abstract: The structural regulation of nanoparticles is a challenging task without any structure determining agents such as templates, surfactants, etc. In the present study, the structure of cadmium sulphide nanoparticles (CdS NPs) has been effortlessly changed from hexagonal to face centred cubic structure under solvothermal conditions by facile volume ratio adjustment of the solvents (water and ethanol). The various CdS NPs prepared have been investigated using different characterisation techniques and their structure, size and morphology vary with respect to the solvent composition. Furthermore, the photocatalytic performance of CdS NPs has been investigated using Methylene Blue (MB) as model organic pollutant. It has been observed that the photocatalytic degradation efficiency of MB is significantly influenced by the structure of CdS NPs.
