Light-Activated Hydroxyapatite Photocatalysts: New Environmentally-Friendly Materials to Mitigate Pollutants
Summary
This systematic review highlights recent advances in hydroxyapatite-based photocatalysts for degrading water pollutants including dyes, pharmaceuticals, and pesticides under light activation. These environmentally-friendly materials show promise as alternatives to conventional water treatment methods. Photocatalytic degradation technologies like these are being explored for breaking down microplastic particles in contaminated water, making this research relevant to emerging microplastic remediation strategies.
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.
