Journal ArticleDOI
Biomorphic activated porous carbons with complex microstructures from lignocellulosic residues
Jeremias de Souza Macedo,Larissa Otubo,Odair Pastor Ferreira,Iara F. Gimenez,Italo Odone Mazali,Ledjane Silva Barreto +5 more
TL;DR: In this paper, a detailed morphological analysis based on scanning electron microscopy with EDX analysis allowed the first description of the anisotropic cellular microstructure of these plant tissues and also evidenced the morphology transformation in all samples.
Journal ArticleDOI
Highly ordered mesoporous silica loaded with dodecylamine for smart anticorrosion coatings
TL;DR: In this article, mesoporous silica structures were loaded with dodecylamine and embedded into an alkyd primer with a weight load ratio of 15.5% and the release of inhibitor was evaluated by electrochemical impedance measurements.
Journal ArticleDOI
An in situ SAXS investigation of the formation of silver nanoparticles and bimetallic silver–gold nanoparticles in controlled wet-chemical reduction synthesis
Paulo R. A. F. Garcia,Oleg Prymak,Viktoria Grasmik,Kevin Pappert,Wagner Wlysses,Larissa Otubo,Matthias Epple,Cristiano L. P. Oliveira +7 more
TL;DR: In this paper, the formation mechanism of the nanoparticles is derived from the structural parameters obtained from the experimental data, and the evolution of the average particle size of pure and alloyed nanoparticles shows that the particle growth occurs initially by a coalescence mechanism.
Journal ArticleDOI
Synthesis of Pt nanoparticles with preferential (1 0 0) orientation directly on the carbon support for Direct Ethanol Fuel Cell
TL;DR: In this article, a Pt nanoparticles with preferential (1/0/0) orientation directly supported on carbon was synthesized by an alcohol-reduction process using KBr as a shape directing agent.
Journal ArticleDOI
Selective catalytic reduction of NOx by CO (CO-SCR) over metal-supported nanoparticles dispersed on porous alumina
Lais F. Oton,Alcineia C. Oliveira,Jesuína Cássia Santiago de Araújo,Rinaldo dos Santos Araújo,Francisco F. de Sousa,Gilberto Dantas Saraiva,Rossano Lang,Larissa Otubo,Gian Carlos da Silva Duarte,Adriana Campos +9 more
TL;DR: In this paper, the selective catalytic reduction of NOx by CO (CO-SCR) was investigated over metals supported on porous alumina and the Pt, Co, Fe and Ni nanoparticles were dispersed on the alumina.
