Abstract Photocatalytic materials have emerged as pivotal in addressing global challenges such as environmental pollution, energy scarcity, and industrial sustainability. This review delves into the principles, mechanisms, and applications of photocatalytic systems, emphasizing their roles in photodegradation and renewable energy production. United Nations (UN) specified a guideline for sustainable development strategies. UN determined 17 goals of sustainable development and the services of photocatalytic materials underwent 4 of these goals to reflect the distinguishable interest and importance of different photocatalytic materials in many fields for various purposes. Advances in material design, nanotechnology, and system integration have significantly advanced this field, aligning it with sustainable development goals. Key materials like TiO 2 , ZnO, g-C 3 N 4 , and quantum dots are highlighted for their unique properties and enhanced photocatalytic activity through modifications such as doping, heterostructure formation, and biopolymer-supported photocatalysts. Practical applications in wastewater treatment, hydrogen production, air purification, and carbon dioxide reduction are comprehensively analyzed, with case studies demonstrating the successful photodegradation of industrial pollutants. The review also explores the integration of photocatalysis with renewable energy sources, addressing challenges like charge carrier recombination and photocatalyst stability. Interdisciplinary approaches, including computational modeling and machine learning, are discussed for designing next-generation photocatalysts, aligning innovations with global sustainability initiatives.
