Plasmon Effect of Ag Nanoparticles on TiO/rGO Nanostructures for Enhanced Energy Harvesting and Environmental Remediation.

We report Ag nanoparticles infused with mesosphere TiO/reduced graphene oxide (rGO) nanosheet (TiO/rGO/Ag) hybrid nanostructures have been successfully fabricated using a series of solution process synthesis routes and an in-situ growth method. The prepared hybrid nanostructure is utilized for the fabrication of photovoltaic cells and the photocatalytic degradation of pollutants. The photovoltaic characteristics of a dye-sensitized solar cell (DSSC) device with plasmonic hybrid nanostructure (TiO/rGO/Ag) photoanode achieved a highest short-circuit current density () of 16.

Oxide-based catalysis: tailoring surface structures organic ligands and related interfacial charge carrier for environmental remediation.

Hierarchical nanostructures and the effects of ligands on their structure formation were investigated. Morphological analysis showed the change in the morphology from nanospindles to hollow hexagonal nanodisks with the change in ligands. Structural analysis exhibited the formation of both hexagonal ZnO and monoclinic CuO structures in the composition.

Hierarchically ordered macroporous TiO architecture via self-assembled strategy for environmental remediation.

Hierarchical orderd macroporous TiO architecture (HOMTA) was prepared with aid of ethylenediamine (EDA) and investigated the impact of amine molecules on the properties of TiO architecture. The different variation of amine molecules (EDA) leads to tunning the morphology under hydrothermal approach which is confirmed by FESEM and TEM analysis. The XRD and Raman studies confirms the crystal structure of anatase and brookite phase of TiO.
