Special Issue "Nanocatalysts in Chemistry: Synthesis and Applications"
A special issue of Nanomaterials (ISSN 2079-4991).
Deadline for manuscript submissions: 29 February 2020.
Sorbonne Universités, Université de Technologie de Compiègne, Compiègne, France
Interests: synthesis and functionalization of nanomaterials for catalysis and biomedical applications; green chemistry and processes: nanocatalyst, sensors, microwave technology and continuous flow
As the world is currently facing enormous problems concerning the climate, energy, and the environment, catalytic technologies appear to be becoming critical to energy, chemical process, and environmental industries. Recently, revitalization of the research on catalytic materials and industrial catalysts was observed with the development of nanotechnology. Indeed, the use of nanomaterials in catalysis and, more particularly, inorganic nanoparticles has attracted many research endeavors around the world in order to develop innovative and greener protocols. These nanoparticles can be utilized as the catalyst or as support and can facilitate the catalytic process in new media such as, for example, water. Moreover, owing to their small size and increased surface area, nanocatalysts have clearly emerged as offering a unique solution at the interface between homogeneous and heterogeneous catalysis, allowing for an increased reaction rate. In addition, nanoparticles provide additional catalytic functionalities due to their unique intrinsic properties (e.g., magnetism, photo-capability). Thus, in this quest for ecocompatible and less expensive catalysts, nanocatalysis is becoming an important field in chemistry, which is applied widely in academia and in industry.
This Special Issue deals with all aspects of nanocatalysis applied to chemistry, from nanocatalyst synthesis and characterization to their various applications in fine chemistry, depollution, energy, and so on. Both original research and comprehensive review papers contributing to the field are welcome.

Abstract: An environmental-friendly and magnetic titanium dioxide graphene nanocomposite (TiO2−x/rGO/Fe3O4) was prepared for efficiently photodegrading imidacloprid pesticides from wastewater under visible-light irradiation (λ>400 nm). Due to the oxygen vacancy introduced into the TiO2 lattice, the light absorption boundary of TiO2−x/rGO/Fe3O4 is significantly extended to the full visible spectrum. Moreover, the charge separation efficiency is considerably enhanced due to the photo-induced electron transfer from TiO2−x to rGO via the Ti-O-C bond. In order to further improve the removal efficiency of organic pesticides, persulfate (PS) was introduced into the reaction system. The good photocatalytic properties of TiO2−x/rGO/Fe3O4 nanocomposite can effectively activate PS to generate the sufficient amount of sulfate radicals and hydroxyl radicals as the active oxidizing species. This study provides a sustainable pathway for the efficient visible-light photodegradation of imidacloprid pesticides via TiO2−x/rGO/Fe3O4 nanocomposites featuring magnetic separation after wastewater treatment in practice.
