ZNO-CUO-AL2O3-TYPE MIXED OXIDES FOR THE PHOTOCATALITICAL DEGRADATION OF THE GALIC ACID.

摘要

There is a variety of methods for the degradation of water contaminants, depending on its nature and concentration. However, pollutants, such as phenols are difficult to degrade, for this reason, the present invention relates to catalysts of the mixed ZnO-CuO-Al2O3 and its obtainment process that provides the ideal characteristics to perform a heterogeneous photocatalytic degradation of galic acid, for the wastewater treatment. Preferably those generated in the chemical industry, such as: wine distillers, olive oil producers, Cork factories, inter alia. These catalysts allow a green process that uses a catalyst and light to mineralize organic compounds, such as phenols.
