Graphenic semiconductors such as carbon nitride are attracting increasing attention as photocatalysts due to their chemical stability, visible light absorption and excellent electronic properties. The photocatalytic activity of nanostructured TiO2 catalysts is constrained by the wide bandgap and concomitant low visible light responsivity of TiO2. In this context we present the formation of new fluorine...
We demonstrate a rapid and facile approach towards scalable patterning of reduced graphene oxide (rGO) for interconnects in flexible electronic applications. We have used controlled UV light exposure for patterning of rGO over spin coated GO film, which has been demonstrated by various patterns of GO-rGO. Optical and conductivity contrast has been supported by spectroscopic data for GO and rGO regions...
A novel heteroleptic iridium complex supported on graphitic carbon nitride was synthesized and used for photoreduction of carbon dioxide under visible light irradiation. The methanol yield obtained after 24 h irradiation was 9934 μmol g−1cat (TON 1241 with respect to Ir) by using triethylamine (TEA) as a sacrificial donor, which was significantly higher as compared to the semiconductor carbon nitride...
A novel graphene oxide (GO)-immobilized heteroleptic iridium complex was synthesized and demonstrated as a first heterogenized homogeneous catalyst for the production of dimethylformamide (DMF) from carbon dioxide, hydrogen, and dimethylamine. The synthesized hybrid catalyst showed comparable activity as homogeneous heteroleptic iridium complex with additional benefits such as facile recovery and...
Hexamolybdenum (Mo6) cluster-based compounds namely Cs2Mo6Bri8Bra6 and (TBA)2Mo6Bri8Bra6 (TBA=tetrabutylammonium) were immobilized on graphene oxide (GO) nanosheets by taking advantage of the high lability of the apical bromide ions with oxygen-functionalities of GO nanosheets. The loading of Mo6 clusters on GO nanosheets was probed by Fourier-transform infrared (FTIR) spectroscopy, X-ray photoelectron...
Herein, we developed a strategy for fabrication of iron oxide infiltrated vertically aligned multiwalled carbon nanotubes (MWCNT forest) sandwiched with reduced graphene oxide (rGO) sheets network for high performance electromagnetic interference (EMI) shielding application which offers a new avenue in this area. Such engineered sandwiched network exhibits enhanced shielding effectiveness compared...
Herein, a novel synthesis process for large scale in situ growth of three dimensional carbon nanotube (CNT) pillared graphene hybrid nanostructure network (GCNT) is demonstrated where simultaneous reduction of graphene oxide (GO) and formation of CNT pillared on the reduced GO (RGO) sheet is carried out in a single-step in a chemical vapor deposition setup. Furthermore, this GCNT (graphene-carbon...
