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 thermostabilit...
