a Identified carbonaceous species retained in the spent LaFeO3/H-ZSM-5(14) during different reaction time. b–f The species determined by gas chromatography-mass spectrometry. g H2CO as the key intermediates in the reaction pathway to form aromatics (aldol-aromatic) inside zeolite. Some typical transition structure during CH2O to aromatics over LaFeO3/H-ZSM-5 catalyst. Spheres in white, brown, red, light blue, and blue represent H, C, O, Al and Si, atoms, respectively.
