A heterogeneous catalytic process to mitigate the acidity of bio-oils caused by the presence of volatile organic acids
(Elsevier, 2021-09)
The removal of the acidity produced by the presence of volatile organic acids in bio-oils, such as acetic acid, assisted by heterogeneous catalysts was investigated. For this purpose, CaO and alumina-supported catalysts ...
The Heterogeneous Photo-Fenton Reaction Using Goethite as Catalyst
(IWA Publishing, 2010-06)
In the present work the degradation of 2-chlorophenol (2-CP) used as model compound, applying the Heterogeneous photo-Fenton reaction, was studied. Small particles of goethite or iron oxyhydroxide were used as a source of ...
Organic/Inorganic heterogeneous silica-based photoredox catalyst for Aza-Henry Reactions
(Wiley VCH Verlag, 2020-03)
The transformation of light into chemical energy is a leitmotiv in the development of sustainable and environmentally concerned chemical processes. Chemists invented original concepts to address this purpose, like photoredox ...
A new catalyst material based on niobia/iron oxide composite on the oxidation of organic contaminants in water via heterogeneous Fenton mechanisms
(Elsevier Science, 2007-01)
The present work describes the preparation of novel materials based on niobia (Nb2O5)/iron oxides and their use as catalyst on oxidizing reactions of organic compounds in aqueous medium with hydrogen peroxide. These new ...
