Characterization and Evaluation of Hydrothermal Liquefaction Char from Alkali Lignin in Subcritical Temperatures.

An evaluation of hydrothermal liquefaction (HTL) char is investigated in this work. Morphological studies, N adsorption behavior, FTIR analysis, thermal behavior, and elemental composition are studied. The HTL char yield showed an increase with higher operating temperatures.

CoS/TiO Nanocomposites for Hydrogen Production under UV Irradiation.

Transition metal chalcogenides have intensively focused on photocatalytic hydrogen production for a decade due to their stronger edge and the quantum confinement effect. This work mainly focuses on synthesis and hydrogen production efficiencies of cobalt disulfide (CoS)-embedded TiO nanocomposites. Materials are synthesized by using a hydrothermal approach and the hydrogen production efficiencies of pristine CoS, TiO nanoparticles and CoS/TiO nanocomposites are compared under UV irradiation.
