“…The stock GOD solution was prepared in the 0.05 M phosphate buffer solution (PBS, pH 7.4) and stored at 4 • C. d-Glucose solution (0.1 M) was prepared and allowed to mutarotate at room temperature overnight before use. G-CdS nanocomposite with the graphene content of 4.6% was synthesized according to the method described in our previous work (Wang et al, 2010b). PBS (0.05 M) of various pH values were prepared by mixing stock standard solutions of NaH 2 PO 4 and Na 2 HPO 4 , and adjusting the pH with 0.05 M H 3 PO 4 or NaOH.…”

“…Wang et al [113] studied the relationship between ECL intensity and the amount of graphene in a graphene-CdS nanocomposite, and they showed competing mechanisms. There is a critical value below which ECL intensity will increase as the amount of graphene increases; however, when the amount of graphene is larger than this critical value, the ECL intensity will decrease even as the amount of graphene is further increased.…”

Abstract-Since the existence of graphene, a material only a single atomic layer thick, was demonstrated about a decade ago, it has caught the attention of researchers worldwide. This paper begins with a historical overview of graphene since its discovery, in 2004, and focuses on a citation-weighted review of graphene-based sensors developed for the detection of biological targets. Based on this statistical analysis, we categorize recent developments in graphene-based biosensors (GBBs) as optimized for detecting 1) proteins, 2) nucleic acids, 3) carbohydrates, or 4) compounds generated by metabolic processes. Existing detection methods employed by these sensors include electrical, electrochemical, and photonic approaches with respect to detecting labeled (or enzyme-assisted) and label-free (or enzyme-free) probe structures. Herein, we focus on graphene-based glucose sensors because glucose-monitoring technology is extremely important in the management of diabetes and many practical examples of these carbohydrate sensors have been developed using the aforementioned detection methods.

“…Many syntheses for CdS-graphene composites have been reported. For instance, Nethravathi et al [54] and Wang et al [55] bubbled H 2 S gas into a solution containing Cd(NO 3 ) 2 and graphene oxide. Chang et al [56] prepared the composites by in situ growth of CdS on pyrenebutyrate functionalized graphene.…”

Graphene is an interesting two-dimensional carbon allotrope that has attracted considerable research interest because of its unique structure and physicochemical properties. Studies have been conducted on graphene-based nanomaterials including modified graphene, graphene/semiconductor hybrids, graphene/metal nanoparticle composites, and graphene-complex oxide composites. These nanomaterials inherit the unique properties of graphene, and the addition of functional groups or the nanoparticle composites on their surfaces improves their performance. Applications of these materials in pollutant removal and environmental remediation have been explored. From the viewpoint of environmental chemistry and materials, this paper reviews recent important advances in synthesis of graphene-related materials and their application in treatment of environmental pollution. The roles of graphene-based materials in pollutant removal and potential research are discussed. graphene, graphene-based material, environmental remediation, pollution Citation:Lü K, Zhao G X, Wang X K. A brief review of graphene-based material synthesis and its application in environmental pollution management. Chin Sci Bull, 2012Bull, , 57: 12231234, doi: 10.1007 Since the discovery of fullerene and carbon nanotubes (CNTs), research has focused on another allotrope of carbon, graphene. Graphene is a two-dimensional nanomaterial that has between one and ten layers of sp 2 -hybridized carbon atoms arranged in six-membered rings. It has many unique properties, including interesting transport phenomena, and high Young's modulus (approximately 1100 GPa) [ Importantly, it could be used in pollutant removal in environmental remediation, which has attracted increasing research in recent few years [5][6][7][8][9][10] and is the focus of this review. Aggregation of graphene layers determines the practical specific surface area, and modification of pristine graphene with other compounds will decrease the aggregation and increase the effective surface area. Graphene with a high specific surface area has a large enough area for pollutant removal and functionalization. Modification of the graphene surface with specific functional groups or nanoparticles could be used to increase the graphene interaction with organic and inorganic pollutants, so they can be removed efficiently from solution through catalytic adsorption or degradation. Based on this, various graphene-based materials have been synthesized; these have enhanced new properties compared to pristine graphene.In this paper, we review recent research advances in graphene-based nanomaterial synthesis and the application of these materials to environmental remediation. Potential future research on high-performance graphene-based nanomaterials for pollutant removal is discussed.
