Room Temperature Synthesis of N-doped Urchin-like Rutile TiO2 Nanostructure With Enhanced Photocatalytic Activity Under Sunlight
We report the synthesis of nitrogen-doped urchin-like rutile TiO2 nanostructure at room temperature without further heat treatment. The process was operated through hydrolysis of Ti(OC4H9)4 employing the direct amination of the product. The samples characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Raman spectroscopy and Brunaue...
متن کاملSurface-enhanced Raman spectroscopy biosensors: excitation spectroscopy for optimisation of substrates fabricated by nanosphere lithography.
In the 28 years since its discovery, surface-enhanced Raman scattering (SERS) has progressed from model system studies of pyridine on a roughened silver electrode to state-of-the-art surface science studies and real-world sensing applications. Each year, the number of SERS publications increases as nanoscale material design techniques advance and the importance of trace analyte detection increa...
متن کاملBiosensing Based on Surface-Enhanced Raman Spectroscopy by Using Metal Nanoparticles
Surface-enhanced Raman spectroscopy (SERS) is a promising tool in the analytical science because it provides good selectivity and sensitivity without the labeling process required by fluorescence detection. This technique consists of locating the target analyte on nanometer range of roughed Au-nanoparticles. The presence of the metal nanoparticles provides a tremendous enhancement to the result...
