The increasing complexity of water pollution challenges has driven significant advancements in ceramic membrane catalytic reactor technology for wastewater treatment. This comprehensive review examines recent developments in the materials science, fabrication techniques, and process optimisation that have enhanced the performance and applicability of these systems. Notable progress has been achieved in developing low-cost ceramic materials, incorporating novel catalytic functionalities, and optimising operational parameters. Advanced fabrication methods, including slip casting, tape casting, and freeze-casting, have enabled the precise control over membrane architecture and pore structure. The integration of nanostructured catalysts and development of hybrid catalyst systems have significantly improved treatment efficiency, particularly for emerging contaminants. Applications span industrial effluents, municipal wastewater, and specialised treatment needs, with demonstrated success in removing persistent organic pollutants, heavy metals, and micropollutants. While challenges remain regarding membrane fouling, catalyst stability, and economic viability, ongoing research in self-cleaning surfaces, catalyst immobilisation, and cost reduction strategies shows promise. The review highlights the technology’s potential for addressing complex water treatment challenges while identifying critical areas for future development in materials innovation, process intensification, and commercial implementation.
