Special Issue Information

Dear Colleagues,

Wastewater discharged from modern chemical industries and other sources is a significant environmental threat. Pollutants present in water, such as nutrients, organic contaminants, metals, dyes, pesticides, and other toxic chemicals, have potentially adverse impacts on the environment. In recent years, we have witnessed tremendous progress in the development of novel techniques for wastewater remediation.

Nanomaterials have gained considerable attention in the past few decades for applications in various fields. Owing to their unique characteristics, nanomaterials have also been widely explored for application in water remediation. Their high surface area, ease of surface modification, presence of abundant functional groups, chemical stability, excellent thermal and mechanical properties, and easy regeneration have made them ideal candidates for the removal of numerous pollutants from water.

The target of this Special Issue is to document the recent advances in this field (via research articles and review), particularly regarding the applications of various nanomaterials in water treatment, including but not limited to the synthesis and application of nanomaterials in adsorption, membranes, nanocomposites, photocatalysis, capacitive deionization, and degradation of pollutants. The goal of this Special Issue is to assist researchers in the field of water treatment to study the current significant progress in nanomaterials toward the development of effective water treatment applications.

Developing efficient adsorbent materials for water treatment is deemed as one of the key solutions towards mitigating the contaminated water problem. Herein, several Hierarchical Porous Carbons (HPCs) with large mesopore volumes (up to 3 cm3/g) and a wide range of BET surface areas (747–1037 m2/g) were synthesized, and their heavy metal removal behaviors were investigated. Specifically, simulated lead and cadmium aqueous solutions were used to investigate the HPCs adsorption performance towards lead and cadmium removal. All the HPCs demonstrated high affinities towards lead removal compared with cadmium. Additionally, a systematic investigation was carried out to understand the structure—performance relationships for the HPCs. Interestingly, varying the adsorbent pore structure leads to different adsorbent behavior for lead compared with cadmium. The textural characteristics of the HPCs have a limited effect on the removal of cadmium ions. Accordingly, to expedite cadmium removal from aqueous samples, factors other than textural characteristics (i.e., surface chemistry) might enhance the removal process. Conversely, the removal of lead ions can be significantly controlled by the HPCs pore structure. HPC1221 (with 17 nm mesopore size, 2.8 cm3/g pore volume, 907 m2/g) showed the maximum adsorption capacity value of 12.32 mg/g for Cd2+ and 89 mg/g for Pb2+ compared to other HPCs. The significant adsorption parameters were evaluated using the response surface methodology (RSM) design. We believe that the reported insights for the structure–performance relationships will be useful for better designing highly efficient adsorbent materials. Full article
