Facile bulk production of highly blue fluorescent graphitic carbon nitride quantum dots and their application as highly selective and sensitive sensors for the detection of mercuric and iodide ions in aqueous media

Sudip Barman、Mriganka Sadhukhan2012-01-01Journal of Materials Chemistry

Highly blue fluorescent graphitic carbon nitride quantum dots (g-CNQDs) were synthesized by a simple microwave mediated method from formamide (HCONH2). The fluorescence emission of g-CNQDs is found to be strongly dependent on solvent, pH as well as on excitation wavelengths; the life time of the emission decreases wit…

Structure, properties and reactivity of polyoxometalates: a theoretical perspective

Xavier López、Jorge J. Carbó、Carles Bó 等 4 位作者2012-01-01Chemical Society Reviews

In the thematic review dedicated to polyoxometalate (POM) chemistry published in Chemical Reviews in 1998, no contribution was devoted to theory. This is not surprising because computational modelling of molecular metal-oxide clusters was in its infancy at that time. Nowadays, the situation has completely changed and…

Graphene/polyaniline nanorod arrays: synthesis and excellent electromagnetic absorption properties

Hailong Yu、Tieshi Wang、Bo Wen 等 10 位作者2012-01-01Journal of Materials Chemistry

In the paper, we find that graphene has a strong dielectric loss, but exhibits very weak attenuation properties to electromagnetic waves due to its high conductivity. As polyaniline nanorods are perpendicularly grown on the surface of graphene by an in situ polymerization process, the electromagnetic absorption proper…
