Graphene oxide supported metallic nanoparticles such as Cu, Ag, Pd, ... has been used as heterogeneous catalyst for the synthesis of 1, 2, 3- triazoles[1,2]. In this work we hope to use CuNPs@GO as an efficient catalyst in the synthesis of N...

A covalently cross‐linked graphene oxide (GO) as a catalyst was prepared by a cross‐linking process using the nucleophilic reaction of zirconium (IV)‐coordinated 5,10,15,20‐tetrakis (aminophenyl)porphyrin (ZrPPh) with carboxyl groups of the edges of...

A new design of hyperbranchedpolyglycidol/ graphene oxide nanocomposite reinforced hollow fiber solid/liquid phase microextraction (HBP/GO -HF- SLPME) coupled with high performance liquid chromatography was used for extraction and determination...

development research so as to achieve a synthetic target in an expeditious way [2]. In

this study a new zirconium-purphirine was immobilized on the edge of graphene oxide

via covalent bond and the its catalytic activity has been tested in synthesis of 3...

Graphene oxide -GO- is a chemical oxidized of graphite carbon material, including hydroxyl,
carboxyl, carbonyls or epoxides functional groups [1, 2]. The presence of these groups on the
GO surface provides reactive sites for the immobilization...

For the first time, this work reports a facile sonochemical route in the synthesis of graphene oxide

nanosheets (GO) via oxidation of graphite (G). The synthesis of GO was carried out in a fast way under

ultrasonic bath irradiation (GO...

In this work, we synthesized graphene oxide nano sheets via bath ultrasonic irradiation (GO-U) under different condition in a facile and fast procedure and compared specific surface area and other characteristics of these samples with graphene oxide...
