CdS-reduced graphene oxide (RGO) composites are successfully synthesized via the microwave-assisted reduction of graphite in a CdS precursor solution using microwave synthesis system. The photocatalytic performances CdS-RGO Cr(VI) investigated. results show that exhibit enhanced performance for with maximum removal rate 92% under visible light irradiation as compared pure (79%) due to increased absorption intensity and electron-hole pair recombination introduction RGO.

The synthesis of two versatile fluorescent metal–organic frameworks (MOFs), [Eu(4-NCP)(1,4-bdc)]n·0.5H2O (1) and [Eu(4-NCP)(4,4′-bpdc)]n·0.75H2O (2) (HNCP = 2-(4-carboxyphenyl)imidazo(4,5-f)-(1,10)phenanthroline, 1,4-H2bdc benzene-1,4-dicarboxylic acid, 4,4′-H2bpdc 4,4′-biphenyldicarboxylic acid), was carried out using a hydrothermal method. These MOFs were characterized through various advanced technologies to determine their structural information. results indicate that both exhibited 3D...

A new well-aligned cone-shaped nanostructure of polypyrrole (WACNP) has been successfully grown on Au substrate by using a simple, one-step, reliable, and template-free anodic deposition method. The formation mechanism WACNP is proposed, in which the hydrogen bonding introduced from phosphate buffer solution (PBS) promotes (PPy), while steric hindrance effect arisen high concentration pyrrole (Py) boosts its vertical alignment further forms nanostructure. 3D, arrayed, nanotubular...

An atomistic model is presented for the melting behavior of a surface and nanosolid, as well their interdependence based on recent "bond order−length−strength" (bond-OLS) correlation mechanism (J. Phys. D 2001, 34, 3470). It suggested that coordination number (CN) atom reduces whereas remaining bonds lower-coordinated relax spontaneously associated with single bond energy rise. Hence, atomic cohesive (a multiplies CN) or heat required loosening at differs from bulk value. Such difference to...

By using nonequilibrium Green's functions in combination with the density functional theory, we investigate electronic transport properties of edge hydrogenated zigzag-edged graphene nanoribbon heterojunctions. Results show that a perfect spin-filtering effect 100% spin polarization and rectifying behavior ratio larger than 105 can be realized by dihydrogenation, which also modulated changing widths two component ribbons.
