Special Issue Information

Dear Colleagues,

The utilization of environmentally benign abundant and renewable materials on the way to a sustainable future is urgent to deal with reality. Among all the possible approaches, synthesizing desirable materials by recycling bioresources is a fascinating and prosperous strategy, while their use for environmental oriented applications further enhances the cyclic economy and sustainability. Wastewater treatment for modern societies is of great demand, in order to overcome the pollution resulting from the industrial and municipality activity. Various technologies are successfully employed towards water remediation, with adsorptive approaches to be regarded as effective and prosperous. Among a plethora of materials utilized in real-life decontamination applications, carbonaceous materials attract interest predominantly as adsorption media due to their affinity against various pollutants. However, they still have some drawbacks and limitations to their application, while their removal capabilities can further be enhanced. Tuning crucial characteristics such as the textural features and surface chemistry heterogeneity can lead to better-performing materials, especially from the perspective of adsorptive removal. A novel trend is the establishment of multifunctional materials that not only retain the pollutants but also possess the ability to either decompose or mineralize them catalytically. Incorporation and nano-engineering of the already efficient carbonaceous materials with reactive nanophases has gathered the interest of the research community. Additionally, the usage of abundant bioresources as feedstocks like biomass can further elevate the green oriented nature of these kinds of medias.  

Considering all the above, this Special Issue targets the latest trends and advances on carbonaceous-based nanostructured materials as well as nanocomposites for environmental oriented applications that reveal adsorptive and/or catalytic performances better than the currently used materials. Emphasis will be given on biomass derived materials, the reusability of the adsorbents, and on novel trends towards enhancement of the catalytic/reactive decomposition or mineralization.

Ordered mesoporous carbon (CMK-3), obtained from an abundant natural source, sugar, was thermochemically modified with dicyandiamide and thiourea as well as by classical oxidization with hydrogen peroxide to introduce specific surface groups. Thermochemical modifications resulted in carbon with almost unchanged porosity and altered surface chemistry while porosity of H2O2-treated carbon was seriously deteriorated. The obtained carbons were tested as sorbents of diclofenac, considered as one of the emerging water contaminants. Changes in porosity and surface chemistry of modified carbons resulted in significant differences with regard to the uptake of diclofenac. Dicyandiamide-modified carbon showed highest uptake of drugs, reaching 241 mg g−1 that is attributed to its developed microporosity as well as surface chemistry composed of basic groups facilitating electrostatic interactions with diclofenac anions. Desorption study showed that diclofenac is strongly bonded, albeit with a different degree depending on the modification of the CMK-carbon. The obtained results were compared with up-to-date literature regarding sorption of diclofenac by carbon-based sorbents. Full article
