Role of Nanomaterials in the Treatment of Wastewater: A Review

Abstract: Water is an essential part of life and its availability is important for all living creatures. On the other side, the world is suffering from a major problem of drinking water. There are several gases, microorganisms and other toxins (chemicals and heavy metals) added into water during rain, flowing water, etc. which is responsible for water pollution. This review article describes various applications of nanomaterial in removing different types of impurities from polluted water. There are various kinds of nanomaterials, which carried huge potential to treat polluted water (containing metal toxin substance, different organic and inorganic impurities) very effectively due to their unique properties like greater surface area, able to work at low concentration, etc. The nanostructured catalytic membranes, nanosorbents and nanophotocatalyst based approaches to remove pollutants from wastewater are eco-friendly and efficient, but they require more energy, more investment in order to purify the wastewater. There are many challenges and issues of wastewater treatment. Some precautions are also required to keep away from ecological and health issues. New modern equipment for wastewater treatment should be flexible, low cost and efficient for the commercialization purpose.

Recent Advances in Metal Decorated Nanomaterials and Their Various Biological Applications: A Review.

Abstract: Nanoparticles (nanoparticles) have received much attention in biological application because of their unique physicochemical properties. The metal- and metal oxide-supported nanomaterials have shown significant therapeutic effect in medical science. The mechanisms related to the interaction of nanoparticles with animal and plant cells can be used to establish its significant role and to improve their activity in health and medical applications. Various attempts have been made to discuss the antibiotic resistance and antimicrobial activity of metal-supported nanoparticles. Despite all these developments, there is still a need to investigate their performance to overcome modern challenges. In this regard, the present review examines the role of various types of metal-supported nanomaterials in different areas such as antibacterial, antifungal, anticancer, and so on. Based on the significant ongoing research and applications, it is expected that metal-supported nanomaterials play an outstanding role not only in medical but also in other important areas.

Outlook on the Role of Microbial Fuel Cells in Remediation of Environmental Pollutants with Electricity Generation

Abstract: A wide variety of pollutants are discharged into water bodies like lakes, rivers, canal, etc. due to the growing world population, industrial development, depletion of water resources, improper disposal of agricultural and native wastes. Water pollution is becoming a severe problem for the whole world from small villages to big cities. The toxic metals and organic dyes pollutants are considered as significant contaminants that cause severe hazards to human beings and aquatic life. The microbial fuel cell (MFC) is the most promising, eco-friendly, and emerging technique. In this technique, microorganisms play an important role in bioremediation of water pollutants simultaneously generating an electric current. In this review, a new approach based on microbial fuel cells for bioremediation of organic dyes and toxic metals has been summarized. This technique offers an alternative with great potential in the field of wastewater treatment. Finally, their applications are discussed to explore the research gaps for future research direction. From a literature survey of more than 170 recent papers, it is evident that MFCs have demonstrated outstanding removal capabilities for various pollutants.

A glimpse into the microbial fuel cells for wastewater treatment with energy generation

Abstract: Energy and water storage are a global challenge due to various factors such as ecological changes, increasing population, increasing demand for energy at both commercial/domestic level, and high material cost. To overcome these problems, microbial fuel cells (MFCs) is considered as an emerging novel technology where one side it can generate electricity and on the other hand it also exhibits better removal efficiency of different pollutants from wastewater. In this technology, MFCs can use natural waste materials to produce energy and is also efficient in wastewater treatment. This review covers the basics of the technology around MFCs, focusing on the mechanism of energy production along with wastewater treatment. Some current challenges regarding the MFCs approach (especially electrode play a vital role in the field of MFCs) and some future perspectives are also addressed in this article. Moreover, electrodes constitute a significant component of this technique in deciding the working efficiency of MFCs during wastewater treatment. Hence, the selection of the electrode is a great challenge to make MFCs more prolific and commercial. Therefore, this review addressed these issues along with the concept of electro microbiology.

Synthesis, characterization of Mo and Mn doped ZnO and their photocatalytic activity for the decolorization of two different chromophoric dyes

Abstract: Using sol–gel method, nano crystalline ZnO particles doped with different concentrations of molybdenum (Mo) and manganese (Mn) (0.2–1.0%) were synthesized. The structural and optical properties were studied with standard analytical techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD) and UV–vis spectroscopy. The crystalline nature of undoped and doped ZnO is indicated by XRD analysis. The SEM images of undoped ZnO showed irregular shape while doped ZnO showed fused supramolecular structure with rough surfaces. The photocatalytic activity of the synthesized particles (ZnO doped with Mo and Mn) was tested by studying the decolorization of two different chromophoric dyes namely Direct Yellow 27 (azo dye) and Acid Blue 129 (anthraquinone dye) with a 500 W halogen linear lamp in the presence of atmospheric oxygen as a function of irradiation time. The results indicate that ZnO with dopant concentration of 0.60% Mo and 0.80% Mn showed the highest photocatalytic activity as compared to the other dopant concentrations for the decolorization of both dyes. In the case of azo dye, 84% decolorization was found while in case of anthraquinone dye, 66% decolorization took place using 0.60% Mo in 390 min.

A review of ZnO nanoparticles as solar photocatalysts: Synthesis, mechanisms and applications

Abstract: Persistent organic pollutants (POPs) are carbon-based chemical substances that are resistant to environmental degradation and may not be completely removed through treatment processes. Their persistence can contribute to adverse health impacts on wild-life and human beings. Thus, the solar photocatalysis process has received increasing attention due to its great potential as a green and eco-friendly process for the elimination of POPs to increase the security of clean water. In this context, ZnO nanostructures have been shown to be prominent photocatalyst candidates to be used in photodegradation owing to the facts that they are low-cost, non-toxic and more efficient in the absorption across a large fraction of the solar spectrum compared to TiO 2 . There are several aspects, however, need to be taken into consideration for further development. The purpose of this paper is to review the photo-degradation mechanisms of POPs and the recent progress in ZnO nanostructured fabrication methods including doping, heterojunction and modification techniques as well as improvements of ZnO as a photocatalyst. The second objective of this review is to evaluate the immobilization of photocatalyst and suspension systems while looking into their future challenges and prospects.
