Since their discovery in the late 1980s, nanomaterials such as carbon fullerene, carbon nanotubes, and ordered mesoporous materials have opened the door to a revolution in the field of nanotechnology, making them one of the most studied materials due to their unique intrinsic optical, magnetic, electrical, and mechanical features. Nanomaterials, which can be distinguished into several classes on the bases of their dimensionality, including one-dimensional (nanotube, nanowire, nanorods), two-dimensional (nanosheets), and three-dimensional (nanoparticles) types, have, over the last few decades, attracted the attention of scientists in many fields of application, including as heterogeneous catalysts in many industries, such as chemical manufacturing, energy-related applications, and environmental remediation, as well as gas sensors, batteries, and optoelectronic devices, among other biomedical and agricultural applications. This Special Issue on Advanced Nanomaterials for Sustainable Energy, Environmental, and Sensing Applications will attempt to cover the most recent advances in nanostructures, concerning, not only their synthesis and characterization but also their functional and smart properties to be applied in scaling factors, such as grain size, thin film thickness, and porosity in the context of a lattice defect model, nanoceramic thin films, nanoscale superlattices, and mesoporous materials. The articles presented in this Special Issue will cover various topics, ranging from different techniques for synthesis and morphological modification to the preparation of catalytic systems and their application in several areas of interest, such as in catalytic processes and energy, environmental, photochemical, and sensing applications. Therefore, this Special Issue welcomes contributions from all researchers working on nanomaterials, as well as on their characterization, properties, and applications.
The Special Issue will cover, but will not be limited to, the following topics: Advanced synthesis;S mart properties; Characterizations; Multifunctional materials; Energy harvesting/storage devices; Sensors; Highly dispersed metal, metal oxide, or metal sulfide nanoparticles; Heterogeneous catalysis supported by nanoparticle materials; Photochemical properties and applications of nanomaterials; Electrochemical and optical properties of nanomaterials.
