CaIn2S4-based heterojunctions have gained significant attention as robust photocatalysts for sustainable environmental applications like organic degradation and H2 production. This study introduces a brief overview of the morphological characteristics of CaIn2S4-based composites and their effects on their catalytic properties. The fabrication of CaIn2S4- based photocatalysts with hierarchical or nanosheet heterostructures could offer an adequate surface area to volume ratio, enhancing the accessibility of pollutants to the catalyst surface and boosting the photodegradation performance. Moreover, the increased active sites reflect positive effects on the visible-light absorption efficiency. The perfect interfacial contact in the CaIn2S4-based composites facilitated the photocarrier transfer, hampered their reunion rate, prolonged their lifetime, and improved their utilization. The morphological durability and stability of CaIn2S4-based composites are also important variables influencing the photoreaction capacity. Finally, the optimization of surface states and morphological defects can modify the electronic structure of CaIn2S4-based semiconductors, improving their optical properties.
