? 2022 Elsevier B.V.In this work, we have successfully synthesized pristine MoS2 (P-MoS2) and Sn-doped MoS2 (D-MoS2) by hydrothermal method for photocatalytic degradation of dye. To enhance the catalytic activities, the samples are dried by the lyophilization process. The structural and morphological analysis were done by XRD, FE-SEM, HR-TEM, UV-Vis and XPS techniques. Dye degradation experiments were conducted for Rhodamine B (RhB) using the synthesized samples under visible light irradiation to compute their photocatalytic activity. We observed that the Lyophilized Sn-doped MoS2 (DL-MoS2) showed enhanced photocatalytic activity than the other synthesized samples. In particular, DL-MoS2 showed a quick and overall degradation ability for RhB in just 20 min with good reusability behaviour and photostability. The excellent photocatalytic activity of DL-MoS2 may be due to accelerated electron transfer upon Sn doping and fast generated electron-hole pair because of a higher surface area of 127 m2/g. Our study revealed that the DL-MoS2 is a good photocatalyst for the complete degradation of RhB dye.
