Nanotechnology is interdisciplinary concept involving different field of life and providing tailored solution in each problem. Environmental pollution in the form of textile wastewater dyes is one of them. Herein, we report cost effective and cheap hydrothermal synthesis of nanosized NiS NPs and their employment for degradation of MB and MO. Microscopic analysis informed us about size of Nanoparticles which is in the range of 25-30 nm and offer a lot of active surface area. Formation of NPs is confirmed by UV-Vis spectra by presence of narrow absorbance peak around 220 nm and DRS informed us its band gap energy about 3.63 eV. Synthesized photocatalyst degraded 88% of MB and 84 % of MO under photocatalytic chamber and comparable degradation under sunlight. Further tuning of band gap can lead to higher performance of photocatalyst for industrial scale application. Nevertheless, these materials possess promising potential for future applications like wastewater treatment and self-cleaning textiles.
