<i>Cotinus coggygria</i> Scop. as a precious landscape shrub and a good afforestation species that is used in the pharmaceutical industry. In this paper, TG-FTIR, TG-DTG, and Py-GC/MS were used to study the biomaterials of <i>Cotinus coggygria</i> used as biofuels and biochemicals under the catalysis of nano-Mo/Fe₂O₃. The wood powder was extracted using a methanol/benzene solution, and the extract was analyzed by FTIR and GC-MS. The results showed that the pyrolysis products of <i>Cotinus coggygria</i> wood were rich in phenols, alcohols, and biofuels. The metal nano-Mo powder played a catalytic role in the interpretation of the gas in the species, where it accelerates gas products. Metal nano-Fe₂O₃ has a certain flame-retardant effect on the burning process of <i>Cotinus coggygria</i> wood, and the residual amount of pyrolysis is greater. The contents of the extract Formamide, 1-Hexanol, Levodopa, and 9,12-Octadecadienoic acid (Z,Z)- are not only widely used industrially but also play an important role in medicine. <i>Cotinus coggygria</i> is therefore an excellent biomaterial for biofuels and biochemicals.
