Fabrication of organic-inorganic hybrid materials on metal surface for optimizing electrochemical performance

Green-High-Performance PMMA–Silica–Li Barrier Coatings

“…A number of recent studies have investigated the effects of the inclusion of different corrosion inhibitors in hybrid coatings based on cerium, lithium, and molybdenum salts and organic inhibitors, such as 2-mercaptobenzimidazole, that are capable of significantly prolonging the service life of metallic components by retarding the progression of corrosion and the self-healing ability [7,[13][14][15][16][17]. In the event of corrosive or mechanical damage, ionic species are released from the bulk into corrosion-affected zones and act as a cathodic inhibitor by reacting with hydroxyls from the oxygen reduction reaction, forming an insoluble layer that prevents the progress of corrosive action [13,14,18].…”

Hybrid Organic-Inorganic Materials on Metallic Surfaces: Fabrication and Electrochemical Performance

“…More interestingly, a significant advance was made by Ko's group [24] on the fabrication of HOI layers on Mg alloys by introducing 2-mercaptobenzimidazole (MBI), a powerful organic corrosion inhibitor with a functional binding agents (FBAs) based on metal hydroxides [24]. The presence of a metal hydroxide as FBAs would make the available microdefects more uniform, providing more sites for local anchoring of MBI molecules, thereby facilitating the growth of OL on the IL surface [24,25].…”

“…The OL is formed on the IL as confirmed by HR-TEM shown in Figure 4d where the fringe with 0.23 nm inter-planar spacing is belong to (1 0 1) lattice plane of Mg(OH)2 and the inorganic particle surrounds the organic since the inter-planar spacing were measured to be 0.47 and 0.59 nm ascribed to (002) and (001) lattice planes of Co(OH)2 and Co(OH)(NO3). As shown in Figure 4e, MBI molecules in ethanolic solution can be adsorbed on the IL as thiol group (-SH) which is a primary core of chemisorption and in the form of anion as thione (-N) or thiolate (-NH) acted as secondary core which reacts with the FBAs-IL through -N-S-bidentate ligand and hydrogen boding (S-H) to form a complex of IL-[Co(OH)2)-Mg(OH)2]-MBI [24]. At the first step of DCC, the electron donation from Co(OH) 2 to Mg (OH) 2 formed a double layer hydroxide, shown in Figure 4b, which provides preferential sites allowing the large MBI cluster agglomerates to grow on the remedied surface.…”

The anisotropic growth of MBI-[Co(OH) 2 -Mg(OH) 2 ] lead to the formation of carnation-like structures as captured in Figure 4c [24].

Oxidative Thermal Conversion of Hydrothermal Derived Precursors toward the Mixed-Metal Cobaltite Spinel Oxides (ZnCo2O4 and NiCo2O4): In-Situ Investigation by Synchrotron-Radiation XRD and XAS Techniques

“…Both materials have significantly attracted extensive consideration in the energy storage field regarding their remarkable electrochemical activities [6,[13][14][15][16]. Moreover, their excellent electrical properties are prime for the fabrication of organic-inorganic hybrid devices which have gained considerable interest recently [17,18]. Therefore, a suitable synthesis condition which could lead to a production of high purity mixed-metal spinel oxides on a large scale is necessary to serve their future demand.…”
