Innovations in Porous Materials for Wastewater Treatment and Resource Recovery

Dear Colleagues,

Innovations in porous materials for wastewater treatment and resource recovery are rapidly transforming the way we clean water and extract valuable products from waste streams. Porous materials—such as metal–organic frameworks (MOFs)—are defined by their high surface areas and tunable porous structures, which make them highly attractive for capturing pollutants and facilitating reactions. These features enable efficient adsorption, filtration, catalysis, and ion exchange, allowing the removal of heavy metals, dyes, pharmaceuticals, and organic contaminants that traditional systems often struggle to eliminate.

Recent research is pushing beyond pollutant removal toward resource recovery. For example, engineered porous materials are being developed to not only purify wastewater but also selectively recover precious metals such as gold, as well as nutrients like ammonia for use as fertilizer, thus supporting circular economy goals. Innovations also include hierarchically porous photocatalysts that enhance light-driven degradation of organic pollutants and advanced ceramic membranes that can reclaim clean water and critical minerals from industrial effluents. Moreover, porous composites improve treatment efficiency for the removal of heavy metals from water while offering greater stability and reusability, addressing key challenges in scalability and cost. Overall, porous materials are enabling more sustainable, energy-efficient wastewater technologies that simultaneously protect water quality and unlock valuable resources from waste.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
