    Homogeneous photocatalysts immobilized on polymeric supports: Environmental and chemical synthesis applications
    (Elsevier, 2021) Prekodravac, J.; Nair, V.; Giannakoudakis, D.A.; Hsu, S.H.-Y.; Colmenares, J.C.
    The interest in homogeneous photocatalysis arises from the high activity and selectivity advantages of controlled photochemical transformations such as synthesis of chemical/pharmaceutical products or complete degradation/mineralization of hazardous compounds. However, the major drawback of homogeneous photocatalytic reactions lies in the separation and recovery of the photocatalyst after the reaction, necessary to make the photocatalytic process eco-friendly. Immobilization of homogeneous photocatalysts on different supports is considered to be a viable method to increase the retainability and reusability of the photocatalyst simultaneously. This chapter aims to provide an in-depth information related to the immobilization of various homogeneous photocatalysts on well-known synthetic and natural polymers. Detailed information related to the potential environmental and chemical synthesis applications of immobilized homogeneous photocatalysts are also discussed. Finally, this chapter concludes with a new direction in emerging technologies for developing better supported photocatalysts. © 2021 Elsevier Inc. All rights reserved.

    Biopolymeric Nanofibrous Materials for Environmental Remediation
    (wiley, 2022) Pallavi, K.C.; Isloor, A.M.
    The present content gathers information regarding the use of nanofibrous materials fabricated out of biopolymers in environmental problems. Biopolymers are environment-friendly and nonhazardous in character. Various conventional methods have been employed so far to solve problems, such as water pollution, air contamination, and soil infertility. Membranes of different types, filtration systems, and various sorbents have been found useful in the removal of contaminants. Apart from all those, nanofibrous materials attain great importance due to their noncomparable high surface area, minute pore size, diameter in the nanorange, and good adsorptive property. Nanofibers can be fabricated out of diverse polymers through various techniques, such as electrospinning. The surface modifications, such as chemical grafting and oxygen plasma treatment induced functional group insertion, can be done, which imparts high potential in respective applications. The present review chapter describes about nanofiber fabrication technique, properties of the resultant nanofiber mat, and their importance in environmental remediation, such as removal of airborne and waterborne contaminants. © 2022 Scrivener Publishing LLC.
