“…Although a particular interest in solid-state synthesis methods is growing due to its great simplicity and ease. Ultrasonication [39], spin coating [40], sonochemical [41], template synthesis [42], self-assembly [43], pulsed laser [44] and ionothermal precipitation [45] are others important methods, but they are less used. In the last decade, more elaborate and robust synthesis methods were reported, but today increasingly simple methods are being sought in favor of green chemistry and scalability.…”

ZnO is an exciting material for photocatalysis applications due to its high activity, easy accessibility of raw materials, low production costs, and nontoxic. Several ZnO nano and microstructures can be obtained, such as nanoparticles, nanorods, micro flowers, microspheres, among others, depending on the preparation method and conditions. ZnO is a wide bandgap semiconductor presenting massive recombination of the generated charge carriers, limiting its photocatalytic efficiency and stability. It is common to mix it with metal, metal oxide, sulfides, polymers, and nanocarbon-based materials to improve its photocatalytic behavior. Therefore, ZnO–nanocarbon composites formation has been a viable alternative that leads to new, more active, and stable photocatalytic systems. Mainly, graphene is a well-known two-dimensional material, which could be an excellent candidate to hybridize with ZnO due to its excellent physical and chemical properties (e.g., high specific surface area, optical transmittance, and thermal conductivity, among others). This review analyses ZnO–graphene nanocomposites’ recent advances, addressing the synthesis methods and the resulting structural, morphological, optical, and electronic properties. Moreover, we examine the ZnO–graphene composites’ role in the photocatalytic degradation of organic/inorganic pollutants.

“…Furthermore, ChCl:EG was used as a carrier and disperser for SiO 2 @Fe 3 O 4 (silica-coated magnetite) ferrofluids selective for Meloxicam [ 103 ], to electrodeposit Ni-Al nanocomposite coatings from NiCl 2 and aluminum dispersions [ 104 ], to synthesize platinum hollow-opened structures with enhanced performance in the electro-chemical oxidation of methanol [ 105 ], and as a solvent for assembling Ag nanoparticles onto copper substrates [ 106 ]. Glyceline was employed in the solvothermal preparation of functionalized metal-organic framework (MOF) nanoparticles containing zirconium [ 107 ], to immobilize Pd nanoparticles [ 108 ], and to deposit ZnO in situ on graphene sheets [ 109 ]. However, the real novelty of the last period consisted, as stated above, in the very large increase in the use of many new and alternative mixtures, often including biomolecules of natural origin.…”

Deep Eutectic Solvents have gained a lot of attention in the last few years because of their vast applicability in a large number of technological processes, the simplicity of their preparation and their high biocompatibility and harmlessness. One of the fields where DES prove to be particularly valuable is the synthesis and modification of inorganic materials—in particular, nanoparticles. In this field, the inherent structural inhomogeneity of DES results in a marked templating effect, which has led to an increasing number of studies focusing on exploiting these new reaction media to prepare nanomaterials. This review aims to provide a summary of the numerous and most recent achievements made in this area, reporting several examples of the newest mixtures obtained by mixing molecules originating from natural feedstocks, as well as linking them to the more consolidated methods that use “classical” DES, such as reline.

“…The compoite showed a higher photocatalytic activity in the degradation of MB than pure ZnO. Jin et al [39] synthesized ZnO nanoparticles on the graphene surface by an ionothermal precipitation method. The addition of graphene narrowed the band gap of ZnO, increased the visible light absorption range, and accelerated the separation of photogenerated carriers.…”

The sewage discharge of industrial wastewater seriously pollutes the water source and rivers, which is very harmful to the health of humans and wildlife. Among those methods for treating wastewater, photocatalysis is a sustainable and environmental-friendly technique for removing the organic pollutants with no secondary pollution. As a popular photocatalyst, graphene/metal oxide nanocomposites have been widely reported in the photocatalysis field. In this review, the recent progress of graphene/metal oxide composites including binary and ternary composites is summarized in detail. The synthesis, microstructure design, and application performance of graphene/TiO2, graphene/ZnO, graphene/SnO2, graphene/WO3, graphene/Fe2O3, and graphene/Cu2O composites are introduced firstly. Then, the synthesis, the selection of components, and the performance of various ternary composites are summarized specifically, including graphene/TiO2-, graphene/ZnO-, graphene/SnO2-, graphene/Cu2O-, graphene/FexOy-, and graphene/Bi-containing ternary composites. At last, the possible research directions of graphene/metal oxide nanocomposites are put forward. The main purpose is to provide a theoretical guidance for designing high-performance graphene/metal oxide photocatalysts for wastewater treatment.
