Titanium dioxide is the most used photocatalyst for processes of environmental remediation and chemical manufacturing
however it is necessary to explore other catalytic materials with similar or better characteristics than TiO2 and also to be active in a wider spectral range like visible light
since this absorbs at wavelengths near to 380 nm corresponding to the ultraviolet range (UV). Given this Delgado et al have developed synthetic methods for the preparation of strontium titanates doped with rare earth elements (A1-y LnyZr0.1Ti0.9O3
con Ln = Eu
Sm
Dy
Ho) which exhibit a redshift on Eg band. In a previous study conducted at the Center for Research in Catalysis
the photocatalytic activity of mixed oxide perovskite doped with rare earth elements such as europium
samarium
dysprosium and holmium were evaluated
results show that the solid doped with Ho has more activity at wavelengths between 450-750 nm. In this research the photocatalytic activity of perovskites Sr(1-x)HoxZrTi0.9O3 con x = 1%
3%
6%
9%
was evaluated using as model reaction photodegradation of methylene blue under aerobically conditions at neutral pH
thus varying the concentration of Ho in the catalyst is expected that Eg band moves to the visible
therefore the effect of incident wavelength was studied for the degradation of methylene blue.

En un estudio previo realizado en el Centro de Investigación en Catálisis, se evaluó la actividad fotocatalítica de óxidos mixtos tipo perovskita dopados con elementos de tierras raras como europio, samario, disprosio y holmio, los resultados obtenidos muestran que el sólido dopado con Ho presenta mayor actividad a longitudes de onda entre 450-750 nm.
