1. Study on the adsorption of heavy metal ions from aqueous solution on modified SBA-15
Amino-functionalized SBA-15 mesoporous silica was prepared, characterized, and used as an adsorbent for heavy metal ions. The organic - inorganic hybrid material was obtained by a grafting procedure using SBA-15 silica with 3-aminopropyl-triethoxysilane and bis(2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272), respectively. The structure and physicochemic

2. Development of palladium nanoparticle catalysts for hydrodechlorination reaction / Desenvolvimento de catalisadores de paládio nanoparticulado para a reação de hidrodescloração
The hydrodechlorination reaction (HDC) has received great attention as an alternative treatment of organic residues, which is more efficient than incineration, especially for aromatic organic compounds, and avoids the formation of toxic species, such as furans and dioxins. The present study is focused on the preparation of supported palladium nanocatalysts f

3. Síntese, caracterização e atividade catalítica de novos catalisadores metaloporfirínicos suportados / Synthesis, characterization and catalytic activity of novel anchored metalloporphyrin catalysts
In this work the second generation metalloporphyrin Me(TFPP)Cl (Me = Fe and Mn) [5,10, 15, 20 ? tetrakis(pentafluorophenyl) porphyrin iron (III) or manganese (III) chloride] was covalently anchored to aminofunctionalyzed supports, through nucleophilic substituition of the para-fluorine atoms of the pentafluorophenyl meso-aryl groups, with the objective of ob
