This work presents the study of the production of hydrogen product of the
degradation of EDTA in the photocatalytic process mediated by SrEuZrTiO3
perovskites impregnated with Nikel in concentrations of 4.5 to 6.5% in relation
to titanium.The catalysts were synthesized by the citrate method achieving
nanometric grains and a homogeneous distribution corroborated by HTEM. For
the performance of the material in the production of hydrogen, the
experimental design is carried out through the response surface methodology
in which it defines alkaline pH, initial EDTA concentration of 50 μL / mol and 30
mg of photocatalyst for hydrogen production of 9700 μmol against irradiation
for 5 hours with simulated sunlight with an argon lamp using photocatalyst
Sr0.97Eu 0.02Zr0.1Ti0.9O3 impregnated with nickel, Factors such as temperature,
stirring rate and light intensity were held constant. he Box-Behnken design was
chosen to investigate the combined effect of the three independent variables
through 17 sets of experiments, including five replicas at the center point. The
experimental values of photocatalytic hydrogen production under all
experimental conditions. The ANOVA implies that the model is significant with
the F value of 36.07. There is only a 0.001% probability that a "Model F-value"
can occur due to noise, and the p value (
