Thionine-graphene oxide covalent hybrid and its interaction with light.
Graphene oxide sheets (GO) were covalently functionalized with thionine molecules. The obtained hybrid material, Th-GO, was characterized by means of scanning electron microscopy (SEM), Auger electron spectroscopy (AES), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. Subsequently, the interaction of light with the free dye molecules and with dye molecules bound to the gr...
متن کاملphotocatalytic degradation of Triton X-100 in aqueous phase with Zinc oxide as a nanoparticle under UV light irradiation
The photocatalytic degradation of nonionic surfactant Triton X-100 was studied by a batch process using ZnOcommercial powders as the catalyst on irradiation with UV light and its behaviour comparatively with respect toZnO nanoparticles with diameter size 20 nm. The effects of different conditions such as catalyst type, amount ofthe photocatalyst, pH of the system, initial concentration and elec...
متن کاملThe n → π* interaction: a rapidly emerging non-covalent interaction.
This perspective describes the current status of a recently discovered non-covalent interaction named as the n → π* interaction, which is very weak and counterintuitive in nature. In this review, we have provided a brief overview of the widespread presence of this interaction in biomacromolecules, small biomolecules and materials, as well as the physical nature of this interaction explored usin...
متن کاملLight harvesting with non covalent carbon nanotube / porphyrin compounds
We present recent developments in the synthesis and in the functional study of non covalently bound porphyrin/carbon nanotube compounds. The issue of the chemical stability of non covalent compounds is tackled by means of micelle assisted chemistry. The non covalent functionalization allows to preserve the electronic integrity of the nanotubes that display bright NIR luminescence. In the same t...
متن کامل‘Spotted Nanoflowers’: Gold-seeded Zinc Oxide Nanohybrid for Selective Bio-capture
Hybrid gold nanostructures seeded into nanotextured zinc oxide (ZnO) nanoflowers (NFs) were created for novel biosensing applications. The selected 'spotted NFs' had a 30-nm-thick gold nanoparticle (AuNP) layer, chosen from a range of AuNP thicknesses, sputtered onto the surface. The generated nanohybrids, characterized by morphological, physical and structural analyses, were uniformly AuNP-see...
