“…Moreover, the decline of the permeate flux may be the result of the driving force decrease in MD due to concentration polarization caused by the increasing concentration of solute in the feed solution. However, even at higher solute concentration, a high permeate flux is still obtained . On the other hand, Garofalo et al obtained a reduction of solute rejection when increasing solute concentration …”

“…It is important to point out that some authors reported that grafting does not block membrane pores, changing only the chemistry of the ceramic membrane . Contrarily, Khemakhem et al reported a reduction of the mean pore size after grafting due to the densification of the membrane surface .…”

“…Hubadillah et al and Kujawa et al proved that ceramic‐based MD can be applied to high concentrated solutions without affecting its performance because of lower fouling effect . On the other hand, many authors observed that when increasing the solute concentration at the feed side results in a decrease in permeate flux . This phenomenon is explained by Raoult's law, which states that higher solute concentrations lead to decrease in water vapor pressure.…”

“…By evaluating membrane characteristics, García‐Fernández et al obtained the best AGMD performance with the hollow fiber membrane having the largest micro‐channel structure, lower thickness, slightly higher void volume fraction and the lowest pore tortuosity factor, that reduced the mass transport resistance . Higher permeate fluxes were observed for membranes with larger pore size .…”

Membrane distillation (MD) has been increasingly studied in the past decade for its potential as a separation process of nonvolatile components. The present study demonstrates a comprehensive overview of the current progress and challenges in the application of ceramic membranes to MD based on the available state of the art.There are already published review papers about MD, but the present study focuses on ceramic membranes, which are still the few used in MD when compared to polymeric membranes. Significant issues such as membrane material, module, characteristics, and hydrophobic modification are discussed. The main operating conditions and their effects on the separation process are given. Current applications of ceramic membranes in MD are also presented. Likewise, challenges and future perspectives associated with MD performance using ceramic membranes are highlighted.A review focused on ceramic membranes applied specifically to MD will contribute for future research in order that this process achieves successful implementation in industry.

“…Compared to polymeric membranes, ceramic membranes can withstand harsh environments due to their excellent mechanical strength, chemical stability, and thermal resistance [10][11][12]. Many researches have been reported to explore ceramic membrane application in MD [13][14][15][16]. Recently, inorganic modifiers were used for ceramic membrane modification to achieve hydrophobic structure.…”

Highly efficient Si 3 N 4 ceramic planar membrane for water desalination process using membrane distillation was prepared by the dual-layer phase inversion tape casting and sintering method. In comparison with typical phase inversion tape casting method, the green tape was formed using Si 3 N 4 slurry on the top and graphite slurry on the bottom. After consuming away the graphite structure, a ceramic membrane consisting of a two-layered structure (skin and finger-like layers) was obtained. The skin layer was relatively tight, and thus could act as a functional layer for separation, while the finger-like layer contained straight open pores with a diameter of 100 μm, acting as a support with low transport resistance. For comparison, typical Si 3 N 4 ceramic membrane was fabricated by phase inversion technique without graphite substrate, resulting in a three-layered structure (skin, finger-like, and sponge layers). After membrane modification from hydrophilic to hydrophobic with polymer derived nanoparticle method, the water desalination performance of the membranes was tested using the sweeping gas membrane distillation (SGMD) with different NaCl feed solutions. With the increase of salt content from 4 to 12 wt%, the water flux decreased slightly while rejection rate maintained over 99.99%. Comparing with typical three-layered Si 3 N 4 membrane, an excellent water flux enhancement of over 83% was resulted and the rejection rate remained over 99.99%.

The control of heat at the nanoscale via the excitation of localized surface plasmons in nanoparticles (NPs) irradiated with light holds great potential in several fields (cancer therapy, catalysis, desalination). To date, most thermoplasmonic applications are based on Ag and Au NPs, whose cost of raw materials inevitably limits the scalability for industrial applications requiring large amounts of photothermal NPs, as in the case of desalination plants. On the other hand, alternative nanomaterials proposed so far exhibit severe restrictions associated with the insufficient photothermal efficacy in the visible, the poor chemical stability, and the challenging scalability. Here, it is demonstrated the outstanding potential of NiSe and CoSe topological nodal‐line semimetals for thermoplasmonics. The anisotropic dielectric properties of NiSe and CoSe activate additional plasmonic resonances. Specifically, NiSe and CoSe NPs support multiple localized surface plasmons in the optical range, resulting in a broadband matching with sunlight radiation spectrum. Finally, it is validated the proposed NiSe and CoSe‐based thermoplasmonic platform by implementing solar‐driven membrane distillation by adopting NiSe and CoSe nanofillers embedded in a polymeric membrane for seawater desalination. Remarkably, replacing Ag with NiSe and CoSe for solar membrane distillation increases the transmembrane flux by 330% and 690%, respectively. Correspondingly, costs of raw materials are also reduced by 24 and 11 times, respectively. The results pave the way for the advent of NiSe and CoSe for efficient and sustainable thermoplasmonics and related applications exploiting sunlight within the paradigm of the circular blue economy.
