Hydrogen Production Using TiO-Based Photocatalysts: A Comprehensive Review.

Titanium dioxide (TiO) is one of the most widely used photocatalysts due to its physical and chemical properties. In this study, hydrogen energy production using TiO- and titanate-based photocatalysts is discussed along with the pros and cons. The mechanism of the photocatalysis has been elaborated to pinpoint the photocatalyst for better performance.

A review on sources of heavy metals, their toxicity and removal technique using physico-chemical processes from wastewater.

The world is facing environmental pollution and is in an alarming situation due to industrialization and urbanization. Especially, industrial wastewater discharge is causing serious pollution in the environment (water, soil, and air) and has become a challenge for researchers and scientists. Wastewater contains heavy metals like Cu, Ni, Cr, Pb, and Ar and causes toxicity in living beings and the environment.
