Synthesis And Characterization Of Graphene Oxide –Polyoxometalate Composite Material For Device Applications.
In: 4th National Conference on Condensed Matter Physics and Applications, 23-24, May 2016, MIT Manipal, India.
Abstract
Polyoxometalates (POMs) consisting of clusters of d-block transition metals and oxygen
atoms represent an important class of water soluble polynuclear nanomaterial. The tuneable
size, structure and elemental composition of POM draws considerable attention for the
development of functional composite materials of desired chemical and electronic
properties.[1] Graphene can be the promising support for POMs due to its low band gap
energy and fast electron transport properties. These properties of grapheme facilitates
transport of electrons of POMs rapidly and effectively.[2] In the present investigation,
graphene oxide (GO) and reduced graphene oxide (rGO) have been used as a support for
POM-graphene composites for semiconductor, hydrogen production applications.[2] The
deposition of POM on graphene oxide sheets were carried out through electron transfer
interaction and electrostatic interaction between POM and GO sheets. ....
