Special Issue Information

Dear Colleagues,

Nanostructured materials have been widely applied in various fields. Recently, nanomaterials have been widely applied in emerging pollutant removal and environmental remediation due to a particular focus on environmental protection. This Special Issue of Nanomaterials is devoted to the design, synthesis, and applications of nanomaterials towards this aim.

This topic provides timely and authoritative information on the nanomaterials being applied in adsorption and oxidation process for emerging pollutant removal and environmental remediation. The overall scope includes fundamental and practical aspects of adsorption and oxidation processes: mathematics, thermodynamics, chemistry, and physics, as well as processes, applications, model engineering, and equipment design. Specifically, it includes the following areas:

  1. Gas-, liquid-, and solid-phase interface process in Emerging Pollutant Removal and Environmental Remediation;
  2. Catalytic Oxidation or reduction reactions in the presence of nanocatalysts;
  3. Adsorption for removing the emerging pollutants and heavy metals by nano-adsorbents;
  4. Biological and biochemical processes in the presence of nanomaterials in Environmental Remediation;
  5. Theorgy calculation for the removal of emerging pollutants and heavy metals by nanomaterials.

As nanotechnology continues to develop, the synthesis, characterization, and application of nanomaterials have attracted significant interest from researchers. The exploration of new and advanced technologies used to synthesize and characterize nanomaterials are particularly encouraged in this issue.

Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study related to nanomaterials. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, are preferred. There is no restriction on the length of the papers; our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be presented for research articles, and computed data or files may also be provided as supplementary materials. Nanomaterials is committed to a high scientific standard; all manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.

Water pollutants harm ecosystems and degrade water quality. At the same time, many pollutants carry potentially valuable chemical energy, measured by chemical oxygen demand (COD). This study highlights the potential for energy harvesting during remediation using photocatalytic fuel cells (PCFCs), stressing the importance of economically viable and sustainable materials. To achieve this, this research explores alternatives to platinum cathodes in photocathodes and aims to develop durable, cost-effective photoanode materials. Here, zinc oxide nanorods of high density are fabricated on carbon fiber surfaces using a low-temperature aqueous chemical growth method that is simple, cost-efficient, and readily scalable. Alternatives to the Pt cathodes frequently used in PCFC research are explored in comparison with screen-printed PEDOT:PSS cathodes. The fabricated ZnO/carbon anode (1.5 × 2 cm2) is used to remove the model pollutant used here and salicylic acid from water (30 mL, 70 μM) is placed under simulated sunlight (0.225 Sun). It was observed that salicylic acid was degraded by 23 ±0.46% at open voltage (OV) and 43.2 ± 0.86% at 1 V with Pt as the counter electrode, degradation was 18.5 ± 0.37% at open voltage (OV) and 44.1 ± 0.88% at 1 V, while PEDOT:PSS was used as the counter electrode over 120 min. This shows that the PEDOT:PSS exhibits an excellent performance with the full potential to provide low-environmental-impact electrodes for PCFCs. Full article
