Light-Activated Hydroxyapatite Photocatalysts: New Environmentally-Friendly Materials to Mitigate Pollutants

Abstract

This review focuses on a reasoned search for articles to treat contaminated water using hydroxyapatite (HAp)-based compounds. In addition, the fundamentals of heterogeneous photocatalysis were considered, combined with parameters that affect the pollutants’ degradation using hydroxyapatite-based photocatalyst design and strategies of this photocatalyst, and the challenges of and perspectives on the development of these materials. Many critical applications have been analyzed to degrade dyes, drugs, and pesticides using HAp-based photocatalysts. This systematic review highlights the recent state-of-the-art advances that enable new paths and good-quality preparations of HAp-derived photocatalysts for photocatalysis.

“…As a result, it imperatively needs techniques to remove pharmaceutical antibiotics-containing wastewater. There have been various methods developed by researchers to eliminate antibiotics such as adsorption (3) , reverse osmosis (4) , advanced oxidation process (5) , and photocatalytic techniques (6)(7)(8) . Among these methods, photocatalyst has been widely used in recent years due to its the eco-friendly operation, inexpensive, and non-toxicity.…”
