Journal ArticleDOI
Highly ordered spherical SBA-15 catalysts for the removal of contaminants from the oil industry
TL;DR: In this paper, a silica SBA-15 with spherical morphology was synthesized via the sol-gel method and applied as a catalyst support of iron nanoparticles with near 20nm diameters (SBA/Fe 9% Fe).
Journal ArticleDOI
Synthesis and characterization of catalysts based on mesoporous silica partially hydrophobized for technological applications
Amanda R. Martins,Adriana Barbosa Salviano,Aline A. S. Oliveira,Raquel V. Mambrini,Flávia C.C. Moura +4 more
TL;DR: In this work, mesoporous silica mobil composition of matter no. 41 (MCM-41) was synthesized by the sol-gel method and may be partially reduced during the CVD process to Fe2+ species, which are stabilized by the carbon coating.
Journal ArticleDOI
N-doped carbon nanotubes grown on red mud residue: Hybrid nanocomposites for technological applications
Aline A. S. Oliveira,Amanda R. Martins,Roberta V. Ferreira,Igor Cunha,Philippe Serp,João Paulo de Mesquita,Flávia C.C. Moura +6 more
TL;DR: In this paper, N-doped carbon nanotubes were grown on the surface of red mud residue to produce hybrid nanocomposites and the structure, composition and amphiphilic properties of the resulting nanocom composites were characterized in detail by physicochemical means such as elemental analysis, thermal analysis, Raman spectroscopy, electron microscopies, BET surface area and Mossbauer spectroscopic analysis.
Journal ArticleDOI
Understanding photocatalytic activity and mechanism of nickel-modified niobium mesoporous nanomaterials
Iza F.B. Silva,Amanda R. Martins,Klaus Krambrock,Marcelo Gonçalves Rosmaninho,Ildefonso Binatti,Flávia C.C. Moura +5 more
TL;DR: In this article, mesoporous Niobium(V) oxides (n-type) with relatively high surface areas were synthesized by Evaporation Induced Self-Assemble method and modified with different amounts of NiO (p-type).
Journal ArticleDOI
Making more with less: confinement effects for more sustainable chemical transformations
TL;DR: In this paper , the authors show that in a bulk homogeneous solution, this is often governed by random collisions based on molecular diffusion, which is known as molecular diffusion in chemistry.
