This work addresses the main point, the synthesis of one-dimensional titanate nanostructures and their ion exchange with transition metals for application in photocatalysis. The catalysts tested in the photocatalytic process were titanate nanoribbons (NRTi) synthesized by hydrothermal method and ion exchanged with Sn2+. The structural and morphological analysis of the material was performed by XRD, Raman spectroscopy and TEM images, confirming the formation of the desired structures and the growth of SnO2 nanoparticles after the ion exchange process with average size smaller than 10 nm. The values of surface area were obtained by BET and showed a significant increment after the ion exchange process, making it favorable for application in photocatalysis. The NRTi was applied in the degradation of blue dye remazol, generating a total degradation in 120 minutes. The rate constants were calculated from the pseudo-first-order equation.

ABSTRACT

In the present work, thin films of FeN (Iron Nitride) and TiN (Titanium Nitride) were deposited in samples of laminated glass by cathodic cage deposition technique using stainless steel and titanium cages, respectively. Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), Wettability and Electrical Conductivity techniques were used to characterize the samples. To obtain the electrical conductivity values, the electrical resistivity (also known as specific electrical resistance) was calculated. In this way, the lower the resistivity, the easier is the passage of an electric charge through the material. To this purpose, it was used the four-point probes method. FeN film presented hydrophobic surface, and TiN film hydrophilic surface.Both films were promising in electrical conductivity analysis. The results show promise applications in the electronic devices.
