Special Issue Information

Dear Colleagues,

Porous carbon materials have versatile applications in the modern world. Different varieties of carbon exist, including activated carbon, nanocarbon, soft and hard templated mesoporous carbon, carbon fibers, or biochar. This Special Issue of Molecules invites submissions of articles that specifically target the application of carbon-based materials toward sustainability. Topics of interest include, but are not limited to, carbon capture, air purification, water purification, trace contaminant removal, and the sensing and removal of chemical warfare agents. We also welcome research on the synthesis of carbon-based materials using a sustainable approach. 

Dr. Dipendu Saha

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. Molecules 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 2700 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.

Valorizing coconut shell waste as a renewable lignocellulosic precursor offers a sustainable route to produce high-performance activated carbons for wastewater treatment. In this study, coconut shells were transformed into activated carbons through physical activation (air, CO2, steam) and chemical activation (H3PO4, ZnCl2, KOH), allowing direct comparison of how each method influences porosity and surface chemistry. Among the physically activated samples, steam activation produced the best material, A-ST, with SBET = 738 m2 g−1, Vmi = 0.38 cm3 g−1 and Vme = 0.07 cm3 g−1. KOH activation yielded the top-performing carbon, A-KOH, achieving SBET = 1600 m2 g−1, Vmi = 0.74 cm3 g−1, and Vme = 0.22 cm3 g−1. Adsorption tests with methylene blue, methyl orange, and orange G showed a clear link between physicochemical features and dye uptake. A-ST and A-KOH exhibited the highest capacities due to their wide micro–mesoporosity and favorable surface charge at the adsorption pH. In both cases, methylene blue was most strongly retained, confirming that large aromatic cations benefit from π–π interactions with graphene-like layers and easy micropore access. Overall, the results demonstrate that coconut-shell valorization is maximized when activation enhances both porosity and surface chemistry, enabling the production of tailored sorbents for the efficient removal of organic contaminants.
