Rice husk Precursor for synthesis of a TiO 2 /SiO 2 mixed catalyst for degradation of methyl violet dye [24] Rice husk Catalyst supported by the incorporation of titania under rice hulls and tested in the degradation of methylene blue under UV radiation [25] Rice husk Catalyst supported on rice hulls to verify its influence on the degradation of phenol and 4-chloro-phenol (4-CP) under UV radiation [26] Rice husk Supported catalyst prepared from the rice husk and used for determination of degradation kinetics of 2-deoxyribose [27] Cellulosefibers Catalyst supported from zinc-based cellulosic fibers for the degradation of bright green [28] Rice husk Precursor in the synthesis of a TiO 2 /SiO 2 catalyst for degradation of methylene blue under UV and visible radiation [29] Rice husk Catalyst supported from rice huskwith TiCl 4 in order to evaluate the photodegradation of methylene blue, naphthalene, phenol and abamectin under UV radiation [30] It is possible to verify that the biomasses can beused as precursors or supports in the preparation of photocatalysts for application in heterogeneous photocatalysis. Also,the lack of scientific studies using porongobiomass( Lagenariasiceraria )is noteworthyand maybe a considerable sustainable source for support in the synthesis of supported photocatalysts for application in heterogeneous photocatalysis for subsequent degradation of pollutants. III. D iscussion It is possible to identify an eco-technological potential of the reuse of the residual porongo biomass ( Lagenariasiceraria ) as a precursor or support for application in heterogeneous photocatalysis. Also, the structural,morphological and textural characterization of this residue to evaluate its applicability in the synthesis of photocatalysts for the degradation of organic pollutants hasfundamental importance for the usage diversification of this raw material.
