“…There are three ways to modify inorganic nanoparticles on GO surface: (a) physical adsorption, (b) in situ growth, and (c) chemical bonding. Due to the large specific surface area of graphene oxide and its extremely strong conjugated structure and negatively charged functional groups, the nanoparticles can be physically adsorbed to obtain inorganic-nanoparticles-modified GO. , On the other hand, since GO has excellent surface physical adsorption capacity of metal ions, it can be grown in situ on GO’s surface through the process of adsorption of inorganic metal salt ions and later rechemical conversion to obtain uniformly distributed and size controllable nanoparticles on GO plane, for example, ZnO, metal organic framework (MOFs), Fe 3 O 4 , hydroxyapatite, CaCO 3 , SiO 2 , , ZrO 2 , and Ag nanoparticles. The last but most commonly used one is to modify the surface of inorganic nanoparticles (ZrO 2 (as pictured in Figure ), Ti, TiO 2 , Al 2 O 3 , and ZSM-5) with bridging molecules (APTES, APS, and ANI), and then to initiate bridging molecules to chemically react with functionalized GO, resulting in inorganic-nanoparticles-modified GO.…”

“…The results show that decorating the surface of a 2D material with 0D nanoparticles can significantly enhance the corrosion resistance of the composite coating by blocking the coating’s inherent micropores better. In anticorrosion, the nanoparticles used for 0D/2D hybrid nanomaterials include SiO 2 , ,, MoS 2 , TiO 2 , , Al 2 O 3 , , Fe 3 O 4 , ,,,, ZrO 2 , , MOF, CeO 2 , , Ag, CaCO 3 , Si 3 N 4 , hydroxyapatite, polypyrrole, fullerene, ZnO, , ZSM-5, Ni, and V 2 O 5 …”

“…However, ZnO material alone cannot provide photoelectrochemical cathodic protection for steels, , and its corrosion inhibition capacity needs to be further improved. Currently, most researchers have tried to solve these problems by compounding the ZnO material with other materials or by designing combined structures. , Although these methods can provide excellent corrosion inhibitors, they cannot optimize the properties of the ZnO material. However, elemental doping makes it possible. …”

“…Therefore, they have a broad application prospect in coatings [21][22][23], sensors [24,25], photoelectric material [26][27][28], medicine [20], and many other fields [29]. For example, Zahra et al [30] used mixed ZnO/GO nanostructures to modify the surface of low carbon steel before acrylic resin coating. Through the structural properties and interactions between the oxygen-containing groups of ZnO and GO structures, the corrosion resistance of low carbon steel was improved.…”
