The global demand for efficient and sustainable water purification is driving rapid innovation in membrane science. Emerging ceramic and zeolite membranes represent a particularly promising frontier, offering an exceptional combination of structural integrity, chemical stability, and precise selectivity for challenging separations. Fully realizing their potential, however, requires a holistic approach that unites novel synthesis, advanced characterization, and a fundamental understanding of underlying transport and fouling mechanisms.

This Research Topic invites original research, comprehensive reviews, and forward-looking perspectives that illuminate the path from laboratory design to practical deployment of ceramic and zeolite membranes. Contributions that bridge synthesis strategies with state-of-the-art characterization—employing cutting-edge analytical, imaging, and spectroscopic tools—are particularly encouraged. Studies providing molecular- or pore-scale mechanistic insights into separation performance, fouling resistance, and long-term stability in complex aqueous environments are of high interest.

Key Areas of Interest:

1. Innovative Materials Design and Synthesis
- Novel fabrication routes for ceramic and zeolite membranes (e.g., additive manufacturing, novel precursors).
- Advanced modification and functionalization strategies to enhance selectivity or anti-fouling properties.
- Design of hybrid or composite membrane structures.

2. Advanced Characterization and Fundamental Mechanisms
- Multi-scale structural, chemical, and interfacial characterization using advanced techniques (e.g., in-situ/operando methods, high-resolution microscopy, spectroscopic analysis).
- Elucidation of mechanisms of molecular and ion transport, selectivity, and fouling.
- Integration of theoretical modeling and computational insights to link material properties with separation performance.

3. Application-Oriented Performance and System Integration
- Performance evaluation in targeted applications: desalination, wastewater reuse, industrial effluent treatment, and resource recovery.
- Removal of specific contaminants, including heavy metals, nutrients, and emerging micropollutants (e.g., PFAS, pharmaceuticals).
- Integration of membranes into hybrid purification systems and scale-up studies.
- Comparative assessments of performance, operational longevity, energy efficiency, and lifecycle sustainability.
