Journal ArticleDOI
The role of oxygen partial pressure and annealing temperature on the formation of W = O bonds in thin WO3 films
TL;DR: In this paper, the authors used x-ray photoelectron spectroscopy to investigate the in-depth composition of tungsten oxide films and found that an increase of the W = O/O/O-W-O ratio was correlated with an increase in the oxygen partial pressure used during the deposition.
Journal ArticleDOI
Meldola blue immobilized on a new SiO2/TiO2/graphite composite for electrocatalytic oxidation of NADH
Camila M. Maroneze,Leliz Ticona Arenas,Rita de Cássia Silva Luz,Edilson Valmir Benvenutti,Richard Landers,Yoshitaka Gushikem +5 more
TL;DR: In this paper, a new SiO 2 /TiO 2/graphite composite was applied in the electrocatalytic oxidation of NADH, decreasing the oxidation potential to −120 mV.
Journal ArticleDOI
Low temperature sulfonation of acai stone biomass derived carbons as acid catalysts for esterification reactions
Rayanne O. Araujo,Jamal da Silva Chaar,Leandro S. Queiroz,Geraldo Narciso da Rocha Filho,Carlos E.F. da Costa,Graziela C.T. da Silva,Richard Landers,Marco Costa,Alexandre A. S. Gonçalves,Luiz K. C. de Souza +9 more
TL;DR: In this paper, X-ray diffraction (XRD), scanning electron microscopy coupled with an EDS system for elemental mapping (SEM-EDS), thermogravimetry (TG), infrared spectroscopy (FT-IR), low-temperature N2 sorption (XPS), and Xray photoelectron spectrogram spectrograms were used to characterize the sulfonated carbon materials.
Journal ArticleDOI
Preparation of supported Pt(0) nanoparticles as efficient recyclable catalysts for hydrogenation of alkenes and ketones
TL;DR: A magnetically recoverable Pt(0) catalyst was prepared by in situ H 2 reduction of Pt 2+ species bound to an amino modified silica-coated magnetic nanoparticles as mentioned in this paper.
Journal ArticleDOI
Lithium insertion and electrochromism in polycrystalline molybdenum oxide films
Fabio Furlan Ferreira,Tersio G.S. Cruz,Márcia Carvalho de Abreu Fantini,Manfredo Harri Tabacniks,Sandra C. de Castro,J. Morais,Abner de Siervo,Richard Landers,Annette Gorenstein +8 more
TL;DR: In this article, molybdenum oxide thin films were deposited by r.f. reactive sputtering of a target in an Ar + O 2 atmosphere, with different compositions and crystal structures obtained by varying the oxygen flow (o).
