Monodispersed tetragonal barium titanate (BaTiO3) nanopowders were synthesized by a convenient hydrothermal route at low temperature of 200?C in only 24 h. The key point this method is to promote the generation ultrafine titanium hydroxide precipitation precursors with help absolute ethyl alcohol and ammonia solution during hydrolysis Ti(OC4H9)4. results X-ray diffraction Raman spectra show tha...

The influence of reaction conditions on the composition of liquid products during two-stage hydrothermal conversion of alkali lignin has been investigated in a batch reactor. Reactions were carried out in the presence of formic acid (FA) and Pt/Al2O3 catalyst. The two different sets of reaction conditions involved alternative reaction times of 1h and 5h at 265°C and 350°C, respectively. These p...
