Abstract: Graphene, a two-dimensional carbon nanomaterial composed of single-layer carbon atoms forming a hexagonal honeycomb lattice via sp2 hybridisation, has attracted extensive worldwide attention since its discovery in 2004. Benefiting from its distinctive atomic structure, graphene exhibits extraordinary physical and chemical properties, such as ultra-high electron mobility, excellent mechanical strength, superior thermal conductivity, and large specific surface area. Nevertheless, the inherent chemical inertness and unsatisfactory dispersibility of pristine graphene severely restrict its practical applications in various fields. Accordingly, the modification of graphene has become a key research direction to address these limitations. This paper systematically reviews the recent research progress of graphene and its modification strategies, mainly including covalent functionalisation, non-covalent functionalisation, and elemental doping. The application advances of modified graphene in energy storage, sensors, composite materials and other high-tech fields are comprehensively summarised. In addition, the existing challenges including mass production, quality stability and cost control, as well as future development trends, are prospected. Studies demonstrate that optimised modification design can effectively improve the performance of graphene-based materials, which hold great promise for wide applications in multidisciplinary areas.

Abstract: Chabazite is a microporous material widely studied due to its applications in heterogeneous catalysis. In this study, the authors synthesized a zeolite by the hydrothermal method at 125°C using tetrapropylammonium bromide as an organic template, which was removed by calcination at 800°C. The characterization of the synthesized product was carried out by X-ray diffraction, Fourier transform infrared spectroscopy, X-ray fluorescence, scanning electron microscopy coupled with energy-dispersive spectroscopy. X-ray diffraction showed the presence of a crystalline phase consisting of chabazite crystallizing in the rhombohedral lattice with lattice parameters a = 9.4250 Å and α = 94.060°. Fourier transform infrared spectroscopy revealed absorption bands located between 400 – 1000 cm-1, characteristic of zeolites. X-ray fluorescence highlighted the aluminosilicate nature with a Si/Al ratio of 4.5 for the synthesized product. The SEM coupled with EDS revealed the uniformity of the product, a hexagonal morphology or the symmetrical facets characteristic of rhombohedral symmetry. The protonated form of the synthesized zeolite, obtained by ion exchange, was used as a catalyst for the synthesis of isoamyl acetate with a yield of the impure product of 79.03%; this yield being close to the same product obtained (84.76%) from the same reaction catalyzed by sulfuric acid. The UV-visible spectral data validated the synthesis products.
