Effect of surfactant concentration on the morphology of MoxSy nanoparticles prepared by a solvothermal route

The preparation of Mo nanoparticles with different morphologies via a surfactant-assisted one-pot solvothermal route was reported. The concentration of surfactant was studied to evaluate its effects on the morphology and the size of the as obtained nanoparticles. The final products were comprehensively characterized using XRD, TEM, HRTEM, IR, TGA and XPS. It was found that at low surfactant concentration, MoS spherical shapes were obtained whereas tubular morphologies are formed at higher concentration. This issue has been discussed based on various relevant experimental data.
