Nanomaterials and their manufacturing technologies have been seamlessly integrated into many applications. For example, nanomaterials find application in aviation and space, chemical industry, optics, solar hydrogen, fuel cell, batteries, sensors, power generation, aeronautic industry, building/construction industry, automotive engineering, consumer electronics, thermoelectric devices, pharmaceuticals, and cosmetic industry. Clean energy and environmental applications often demand the development of novel nanomaterials that can provide shortest reaction pathways for the enhancement of reaction kinetics. Understanding the physicochemical, structural, microstructural, and surface properties of nanomaterials is vital for achieving the required efficiency, cycle life, and sustainability in various technological applications. Nanomaterials can be synthesized in a number of shapes, each with unique properties. These include nanotubes, nanofibers/nanowires, nanocones, nanorods, nanoislands, nanoparticles, nanospheres, and nanoshells. The proposed special issue is timely in bringing out the salient research paradigms of nanomaterials and their potential impacts on clean energy generation, storage, utilization, waste heat recovery, and environmental detoxification and disinfection for a sustainable life on our fragile planet Earth.
