2D graphene oxide (GO) with large surface area, multivalent structure can easily bind single-stranded DNA/RNA (aptamers) through hydrophobic/π-stacking interactions, whereas aptamers having small size, excellent chemical stability and low immunogenicity bind to their targets with high affinity and spec...
Among these preparation methods, solution-based reduction of graphite oxide (GO) is attractive for its easy operation in recent years. It includes three typical steps in this method. They are graphite oxidation, GO aqueous dispersion, and GO reduction. The methods invented by Brodie, Staudenmaier,...
In this work, we present the effect of initial graphite particle size and shape on oxidation time in graphene oxide prepared by Hummers' method. This helps control the oxidation producer, which can be useful in large scale production of graphite oxide. 2. Experimental 2.1. Materials Experiments ...
The present invention relates to the technical field of industrial water and waste water, particularly relates to an improved method of Preparation Method Hummers graphene oxide. 改进Hummers法制备氧化石墨烯的方法,将石墨粉放进,三颈烧瓶中,并加入混合液;在冰浴条件下,加入KMnO4,将混合液,搅拌;将反应得到...
For example Hummers method of oxidation produces higher amount of carbonyl and carboxylic groups than Staudenmaier method because of different oxidizing mixtures as shown in Fig. 3.10 [66]. This is why graphene oxide should be prepared by the same method when comparing different reduction methods, ...
Graphene oxide (GO) is a promising material for energy storage device applications. Modified Hummers method (MHM) has been used to prepare GO films from graphite flakes by Sol-Gel method. With the aid of bridging agent dimethyldichlorosiline, structurally fine GO films were prepared. Fourier tran...
Graphene Oxide (GO): GO was prepared by modified Hummers method51. In this process, graphite powder (1 g) and sodium nitrate (NaNO3, 1 g) were dissolved in H2SO4 (46 ml) in an ice bath. Thereafter, KMnO4 (6 g) flakes was slowly added to the above mixture under stirring...
After the successful preparation of empirical double network hydrogel beads from graphene oxide/sodium alginate(GO/SA), its cationic metal adsorption performance in aqueous solutions were investigated. Taking Mn(II) as an example, the contribution of sev
An improved method for the preparation of graphene oxide (GO) is described. Currently, Hummers' method (KMnO(4), NaNO(3), H(2)SO(4)) is the most common method used for preparing graphene oxide. We have found that excluding the NaNO(3), increasing the amount of KMnO(4), and perfor...
