Sustainable Green Nanotechnologies for Innovative Purifications of Water

Dear Colleagues,

Protecting aquatic ecosystems from pollution and hydromorphological changes and preserving the sustainability of water is crucial for current and future generations, as well as for maintaining political stability at any level. In general, a comprehensive water policy aims at ensuring that a sufficient quantity of good-quality water is available for both human needs and the environment, through regulating the main sources of pollution (e.g., from agriculture, industry, urban wastewaters), water usages (surface, groundwater, and drinking water), and integrated water management. The current priority is to find innovative solutions for the development of cost-effective, economically feasible, and sustainable environmentally friendly technologies for purifications of water.

This Special Issue focuses on advances in semiconductor materials (powders, ceramics, glass ceramics, thin films) processing, characterization, and their multidisciplinary applications. Especially welcomed are papers with a focus on sustainable green nanotechnology, synthesis of semiconductor materials from plant extracts, various precursors, and doping agents (based on non-metals, transition metals) for the removal of (emerging) organic pollutants (e.g., pesticides, pharmaceuticals, dyes from ultrapure, drinking, surface, ground, and wastewaters). This includes the application of “reagent-free, waste-free” advanced oxidation processes (AOPs). Topics regarding individual, as well as additive and synergistic effects obtained by operating hybrid AOPs (including photocatalysis, subcritical water treatments, ultrasound, plasma-based AOP, (photo)-Fenton, catalytic ozonation) are also welcomed.

Articles presented in this Special Issue will cover various topics, ranging from the synthesis and characterization of semiconductors (metal oxides, metal chalcogenides, metal–organic frameworks) to their specific applications of which foremost is the progress in photocatalysis, subcritical water treatments, and advanced oxidation processes in general. Additionally, of particular interest are applications of optical sensor systems as broad indicators of water quality during different treatments.
