Abstract

Cu₂O-based binary heterojunction photocatalysts have emerged as promising candidates for the degradation of organic pollutants, offering a sustainable solution for environmental remediation. This review provides a comprehensive overview of recent advancements and challenges in the development and application of Cu₂O-based binary heterojunction photocatalysts. The synergistic integration of Cu₂O with other semiconductors has been shown to significantly enhance photocatalytic activity through improved charge separation and light absorption. Various synthesis methods, including sol–gel, hydrothermal, and chemical thermal oxidation, have enabled precise tailoring of structural and functional properties to optimize performance. We highlight cutting-edge developments in photocatalytic degradation technologies addressing a wide range of organic pollutants, including pharmaceuticals, dyes, and industrial chemicals. Furthermore, we discuss existing limitations and propose future directions to improve efficiency and scalability, underlining the critical role of these photocatalysts in advancing sustainable environmental cleanup efforts.
