New Insight on Promoted thermostability of poplar wood modified by MnFe₂O₄ nanoparticles through the pyrolysis behaviors and kinetic study.

ABSTRACT: In this study, we employed pyrolysis behavior and kinetics by Flynn-Wall-Ozawa method and Friedman method to analysis the thermostability of the MnFe₂O₄ nanoparticles/poplar wood composite, and analyzed the change of different proportion of MnFe₂O₄ in these composites for the thermostability by contrasting activation energy between the different samples. The pyrolysis processes of these composites were comprehensively investigated at different heating rates (10, 20, 30 and 40 °C/min^-1) and pyrolysis temperatures of 600 °C in N₂ and air atmosphere. These results indicated the thermostability of composites improved as the proportion of the MnFe₂O₄ nanoparticles increased. And the structure analyses of the
