Abstract
This paper presents a spectral analysis of tests performed on a photocatalytic model reaction based on phenol activity diluted in water with doped titanium oxide using as catalyst and irradiated with a coherent beam of light, whose wave front is the superposition of the optical vortices with integer orbital angular momentum opposite.Primarily, the architecture of the system optoelectronics and chemistry related is described, then is selected by discrete test of beams propagated the appropriate wavelength (405 and 450 nm) to project optical vortices over the sample. Finally, the processing and analysis of the signals acquired by a spectrophotometry UV, corresponding to the samples irradiated with the controlled spatial distributions of light by hologram generated computer. © 2018.
