Journal ArticleDOI
Lanthanum doped titania decorated with silver plasmonic nanoparticles with enhanced photocatalytic activity under UV-visible light
TL;DR: In this paper, a simple ultrasound-assisted wet impregnation method followed by silver photodeposition was used to obtain photocatalysts with different Ag contents, which were characterized by XRD, FE-SEM, EDX, TEM, BET, XPS, DRS and PL techniques.
Journal ArticleDOI
An adsorbent with a high adsorption capacity obtained from the cellulose sludge of industrial residues.
Gessica Orlandi,Jéssica Cavasotto,Francisco Roberto da Silva Machado Jr,Gustavo Lopes Colpani,Jacir Dal Magro,Francieli Dalcanton,Josiane Maria Muneron de Mello,Márcio Antônio Fiori +7 more
TL;DR: The cellulose sludge generated by the cellulose and paper industries could be used as an adsorbent and the Langmuir-Freudlich isotherm adequately described the experimental data.
Journal ArticleDOI
Carboxymethyl-β-cyclodextrin functionalization of TiO2 doped with lanthanum: characterization and enhancement of photocatalytic activity
Gustavo Lopes Colpani,Jessica Taísa Zanetti,Fabiele Cecchin,Adrieli T.O. Dal’Toé,Márcio Antônio Fiori,Regina de Fátima Peralta Muniz Moreira,Cíntia Soares +6 more
TL;DR: In this article, the surface functionalization with carboxymethyl-β-cyclodextrin (CMCD) of lanthanum-doped TiO2 nanoparticles was proposed to increase their photocatalytic activity for the degradation of organic molecules.
Journal ArticleDOI
Synthesis of geranyl acetate by esterification of geraniol with acetic anhydride through heterogeneous catalysis using ion exchange resin
Rubieli Carla Frezza Zeferino,Vinicius Aleixo Angonese Piaia,Vinícius Tres Orso,Vítor Machado Pinheiro,Micheli Zanetti,Gustavo Lopes Colpani,Natan Padoin,Cíntia Soares,Márcio Antônio Fiori,Humberto Gracher Riella +9 more
TL;DR: In this paper, Geraniol esterification reaction with acetic anhydride was monitored by gas chromatography and the chemical structure of geranyl acetate was confirmed by mass spectrometry and nuclear magnetic resonance spectroscopy.
Journal ArticleDOI
Fe3O4@C core-shell nanoparticles as adsorbent of ionic zinc: evaluating of the adsorptive capacity
Tauana Rhodio da Costa,Eduarda Baldi,Amanda Figueiró,Gustavo Lopes Colpani,Luciano Luiz Silva,Micheli Zanetti,Josiane Maria Muneron de Mello,Márcio Antônio Fiori +7 more
TL;DR: In this paper, core-shell nanoparticles were synthesized and used to adsorb ionic zinc species in aqueous solutions, with a maximum efficiency equal 65% where applied in an aqueously solution containing 10 mg·l-1 of this ionic metal.
