The rapid use of organic dyes for industrial purposes has led to water pollution, which has sparked a lot of interest towards photocatalytic applications. The most affordable, green and widespread method of treating aquatic wastewater is by breakdown of the dye molecules with photocatalysts in the presence of daylight. Therefore, it is necessary to create photocatalytic materials that, when exposed to natural light, can produce reactive oxygen species. So, keeping in mind the aforementioned point, sol gel technique was used to synthesize Tin oxide (SnO2) nanoparticles at three distinct temperatures such as 350 °C, 450 °C and 550 °C respectively. This article reports the significant degradation application of SnO2nanoparticles against Malachite Green (MG) dye under direct sunlight illumination. The removal of dye concentration found to be escalating with the increase in calcination temperature, as it repress the electron hole recombination process. The enhanced dye remediation rate of the as-synthesized nanoparticles achieved at550 °C of 88.9% can ascribed due to the lower energy bandgap value.
