Abstract Highly ordered 2-D mesostructured MoS 2 was prepared by a nanocasting approach using mesoporous silica SBA-15 as a hard template and phosphomolybdic acid (H 3 PMo 12 O 40 ) as a precursor. The resulting material constructed by interconnected aligned and regularly packed nanowires shows a rod-shaped morphology (0.4–0.7 μm in diameter and 0.8–1.2 μm in length). This mesoporous MoS 2 exhibits reversible lithium storage capacity as high as 630 mAh g −1 with excellent cycling performance when used as an electrode material for lithium ion batteries.

Bioremediation through biotechnological interventions has attracted more attention among researchers in field of environmental pollution control and abatement. Various cutting-edge studies in area of protein engineering and synthetic biology offer a new platform for creation of innovative, advanced biological materials for its beneficial role in environmental pollution mitigation. Biocatalysis especially receives considerable attention as sustainable approach to resource recovery from waste along with elimination of pollutants. This paper focuses on updated developments in engineering of biocatalytic substances which can degrade pollutants of emerging concern. It also explains various classes of biocatalysts, their mechanisms of immobilization, and applications in terms of environmental pollutant remediation. Opportunities and challenges for future research have also been discussed.

Engineering biocatalytic material for the remediation of pollutants: A comprehensive review

Mesoporous silica materials made by the use of self-assembled surfactants as templates have attracted a lot of interest in recent years. The number of publications on the topic has increased by a factor of 100 between 1993 and 2003. The vast majority of the papers deal with syntheses from organosilicates, such as tetramethylorthosilicate (TMOS) and tetraethylorthosilicate (TEOS), as the silica source. These alkoxides are convenient as a starting material but they are expensive and the products made from them can only find use in applications where price is not a major issue. This review summarizes the published work on the preparation of mesoporous silica from inorganic sources, such as water glass and silica sol, still using self-assembled surfactants as the template. The use of such raw materials instead of the organosilicates will radically change the production price of the products and may open up completely new fields of application. Much less work has been put into the synthesis of mesoporous silica from these starting materials and relatively little is known about the reaction mechanism. The current understanding is summarized and discussed and comparisons are made with the conventional route that originates from the organosilicates.

The ligninolytic multi-copper enzyme laccase, is widely produced by bacteria and fungi. It has been extensively used in industries for its versatile applications due to its catalytic properties of oxidation of both phenolic and non-phenolic lignin based compounds. For this purpose, the enzyme needs to be produced in large quantities. Though there have been multiple reviews focused on the biochemical aspects, molecular properties and wide applications of laccases, none of them have elaborately discussed on their production, which is the prerequisite for its use. Through this review a novel attempt has been made to discuss the production strategies of laccases from mesophilic and extremophilic microorganisms using different media ingredients, agro-industrial wastes and culture conditions. These enzymes from various sources possess unique properties, yet sharing some common structural and catalytic features which can be improved using enzyme immobilization techniques. The review also outlines various applications of laccases in different industries including food, textile, paper and pulp. The enzyme has also been used for green synthesis of nanoparticles. Further, its use in biosensors and polymer syntheses have also been elaborated.

Porous nanostructures having well-defined pore structures and surface functionalities are widely used in different areas of applied science and engineering. Depending upon the pore size and framework building blocks, there are a total of six types of nanoporous materials available. Due to the large surface to volume ratio in addition to the interlinked connection with reactant pathways of some porous nanostructures, they have been reported as good-quality chemical and physical catalysts. Different porous nanostructures are used in electrochemical biosensors, and they are also widely used in rechargeable batteries, mostly in Li-ion batteries, in solar cells due to their reflectivity properties, and as electrode materials in the production of high-performance supercapacitors for their porosity and distribution properties of their pore size. Increased surface area and porous structures help in applications of these nanomaterials in treatments of environmental pollutants. Metallic porous nanostructures are also used in random lasers for their localized surface plasmon resonance properties.

Silver-containing nanocomposites have recently attracted the immense attention of researchers from different fields because of the dual benefits from silver nanoparticle and matrix elements. There are four types of synthetic methods or silver nanoparticles and three types of composite systems currently used for their preparations, which are briefly described in this chapter. Silver nanoparticles are widely used for biomedical applications due to their antibacterial and antiviral properties. In addition, silver nanocomposites are extensively used in other fields including, food industries, textile industries, electronic industries etc. Silver nanoparticles embedded polymer matrix composites are promising candidates for biomaterials, photovoltaic materials, and catalysts. This chapter describes different methods employed for synthesis of silver nanoparticle-containing nanocomposites and their potential applications.
