Synthesis of titanate nanofibers co-sensitized with ZnS and Bi2S3 nanocrystallites and their application on pollutants removal
T. J. Entradas, J. C. Cabrita, B. Barrocas +3
The synthesis of nanocomposite materials combining titanate nanofibers (TNF) with nanocrystalline ZnS and Bi2S3 semiconductors is described in this work. The TNF were produced via…
Synthesis of sub-5 nm Co-doped SnO nanoparticles and their structural, microstructural, optical and photocatalytic properties
T. Entradas, J. Cabrita, S. Dalui +3
A swift chemical route to synthesize Co-doped SnO nanopowders is described. Pure and highly stable SnCoO (0 x 0.15) crystalline nanoparticles we…
Synthesis and properties of Co-doped titanate nanotubes and their optical sensitization with methylene blue
V. C. Ferreira, M. R. Nunes, A. J. Silvestre +1
Here we report on a novel chemical route to synthesize homogenous cobalt doped titanate nanotubes (CoTNT), using an amorphous Co-doped precursor. The influence of the synthesis tem…
Influence of the sodium/proton replacement on the structural, morphological and photocatalytic properties of titanate nanotubes
V. Bem, M. C. Neves, M. R. Nunes +2
Titanate nanotubes (TNT) with different sodium contents have been synthesised using a hydrothermal approach and a swift and highly controllable post-washing processes. The influenc…
Synthesis of titanate nanostructures using amorphous precursor material and their adsorption/photocatalytic properties
E. K. Ylhainen, M. R. Nunes, A. J. Silvestre +1
This paper reports on a new and swift hydrothermal chemical route to prepare titanate nanostructures (TNS) avoiding the use of crystalline TiO2 as starting material. The synthesis…
Ferromagnetic order in aged Co-doped TiO2 anatase nanopowders
A. J. Silvestre, L. C. J. Pereira, M. R. Nunes +1
Oxide based diluted magnetic semiconductor (DMS) materials have been a subject of increasing interest due to reports of room temperature ferromagnetism in several systems and their…
