Background: Nano-photocatalysis through semiconductor-based materials has become an emerging and eye-catching approach for detoxification of hazardous heavy metals in the aqueous environment.

Method: In this article, photocatalysis being a green technique along with several other detoxification technologies for toxic heavy metals have been reviewed.

Toxic Effects: Further, the adverse effects of heavy metals on human health, agriculture lands, environment, and aquatic system were investigated. Toxic heavy-metals contribute to numerous environmental issues based on their toxicity.

Result: Various types of photocatalysts were revised in recent literature for the detoxification of heavy metals. The recycling of photocatalysts may be anticipated as a worthy method for wastewater treatment has also been discussed with recent examples.

Conclusion: Moreover, it concludes with efficiency, challenges and new future perspectives for heavy metal detoxification using photocatalysis.

Keywords: Nano-Photocatalysis, Environmental Issues, Heavy metals, Treatment Technologies, Efficient Removal, Detoxification
