In this article, we report the results of the photocatalytic effect of the cost effective grown SnSe nanoparticles (NPs), nanoflakes (NFs), nanoflowers (NFLs) on the toxic water contaminant dye of Rhodamine B (RhB) under visible light irradiation different duration time. The results showed that for the degradation of 99 %, 96 % and 94 % of the RhB have been occurred in presence of NFs, NFLs, NPs, respectively for the irradiation time of 30 min, 45 min, 65 min, respectively. Before photocatalytic test, the grown SnSe were characterised optically and structurally. The nanoparticles, nano flakes, nanoflowers morphology along with atomic composition of Sn and Se were observed from FESEM images and EDAX analysis. The direct band gap of the NPs, NFs, NFLs was calculated from UV‐VIS spectrum and found to be 1.89 eV, 1.78 eV, 1.7 eV, respectively. The crystal structure showed orthorhombic crystal phase with nanocrystal sizes varies from 22 nm to 31 nm. The Scavenger test in presence of the scavenging elements BQ, IPA, ethanol and EDTA have been discussed. The stability test showed that SnSe NFs is a good and stable catalysis for practical applications. The effect of the NFs, NPs, NFLs on red blood cell showed that all the tested SnSe nanostructures had <2 % hemolysis, suggesting their hemocompatible nature.
