Photocatalytic and Adsorptional Removal of Heavy Metals from Contaminated Water using Nanohybrids

Water contaminated with heavy metals is a major menace for aquatic life and human health consequently its efficient removal remains a crucial challenge for researcher. The utilization of various photocatalytic nanohybrids to synergistically photo-reduce and adsorb heavy metals is a potent strategy to combat water pollution. This book chapter give an overview of the fundamental principle of photocatalysis and various single, binary, ternary and quaternary nanohybrids employed for simultaneous photoreduction and adsorption of heavy metals with its mechanistic insight. Further, conclusion and future prospective as well as limitation of available nanohybrids were addressed. We hope that this book chapter dispenses some noticeable information to heavy metal ions removal from polluted water.
