“…The shape of the obtained isotherms suggested the presence of not only slit pores, which are also characteristic for graphenes, but also cylindrical ones. 37,38 The results of the physical properties of the analyzed samples are presented in Table 5. As expected, the BET specic surface area of the pure Ti 3 C 2 was signicantly larger than the specic surface area of modied samples.…”

“…S2 †) Table S1. † 17,21 The controlled, compact and elongated oriented entanglement of g-Al 2 O 3 nanorods on the rGO layer resulted in a higher surface area and lower density in g-Al 2 O 3 -rGO as compared to bare g-Al 2 O 3 . Thus, the presence of rGO in hybrids can increase their BET surface area, pore volume and thermal conductivity.…”

aIn this study, a solvothermal method was employed for the first time to fabricate hybrids composed of crosslinked g-Al 2 O 3 nanorods and reduced graphite oxide (rGO) platelets. After calcination and hot-press processing, monoliths of Al 2 O 3 -rGO hybrids were obtained with improved physical properties. It was found that the oxygen-containing groups on graphene oxide were beneficial for the adsorption of aluminum isopropoxide, leading to a uniform dispersion of rGO with Al 2 O 3 , which was obtained by hydrolysis of aluminum isopropoxide during the solvothermal reaction. The hybrid, which was subsequently calcinated for 3 h showed electrical conductivity of 6.7 Â 10 1 S m À1 together with 90%higher mechanical tensile strength and 80% higher thermal conductivity as compared to the bare Al 2 O 3 . In addition, the dielectric constant of the hybrid was 12 times higher than that of the bare Al 2 O 3 . In this study, the highest values of electrical conductivity (8. 10 4 ) and Young's modulus (3.7 GPa) were obtained for the alumina-rGO hybrid calcinated for 1 h. XRD characterization showed that an increase in calcination temperature and further hot-press processing at 900 C led to enhanced crystallinity in the g-Al 2 O 3 nanorods in the hybrid, resulting in enhanced physical properties in the hybrids.

“…The method involves a reactive metal-organic aluminum compound (triethylaluminium) as the reagent and source of Al in a water and oxygen-free environment ( Jastrzębska et al, 2015 ). The analysis of the final powdered product confirmed that Al 2 O 3 nanoparticles covered uniformly the RGO surface, while the GO was reduced to RGO ( Jastrzębska et al, 2016a ). During the process, triethylaluminium reacts with terminal functional groups (i.e., C=O, O=C-OH, C 2 O, C-OH) present on the surface of GO.…”

Graphene-based nanocomposites constitute an interesting and promising material for various applications. Intensive progress in the development of this group of materials offers an opportunity to create new systems useful for drinking water decontamination or other biotechnological applications. Nanohybrid structures of graphene-ceramic systems can be obtained using covalent graphene surface modification with nanoparticles (NPs) of ceramic and/or co-deposition of metals with selected morphology and chemistry. The present paper systematizes the associated bio-related knowledge and inspires future development of graphene/NPs systems. Emerging knowledge and unique research techniques are reviewed within designing the required nanocomposite structure and chemical composition, development and optimization of new methods of covalent surface modification of graphene with NPs as well as analysis of mechanisms governing the formation of covalent bonding. Further, innovative research tools and methodologies are presented regarding the adjustment of functionalities of materials used for the application in drinking water decontamination or biocidal composites. This study provides a comprehensive base for rational development of more complex, hybrid graphene-based nanomaterials with various bio-functionalities that can be further applied in industrial practice.
