A preparation method for a metallocene compound, the method comprising: stirring at least one compound I among compounds expressed by the following chemical formula and a hydrogenation reaction catalyst of 0.10 to 0.55 parts by weight based on 100 parts by weight of the compound I under a hydrogen atmosphere; and obtaining a metallocene compound containing at least one first compound among the compounds expressed by the following chemical formula in each of the chemical formula and the chemical formula, M is any one of titanium (Ti), zirconium (Zr) or hafnium (Hf); Q is any one of carbon, silicon (Si), germanium (Ge), or tin (Sn); X is independently any one of halogen, an alkyl group having 1 to 10 carbon atoms, and an alkenyl group having 2 to 10 carbon atoms; R 1, R 2, R 3, R 4, R 5, R 6, R 7, R 8, R 9, R 10, R 11, and R 12 satisfy the following (i) or (ii), and each of R 13 and R 14 is independently an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 14 carbon atoms. (i) each of R 1, R 2, R 3, R 4, R 5, R 6, R 7, R 8, R 9, R 10, R 11, and R 12 is independently any one of hydrogen, an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms and an aryl group having 6 to 14 carbon atoms. (ii) among R m (m is an integer of 1 to 12), two adjacent R n and R n+1 (n is an integer from 1 to 11) are connected to each other to form a monocyclic or polycyclic rings having 3 to 15 carbon atoms in which the alkyl group having 1 to 4 carbon atoms is substituted or not substituted, and at this time, the remaining R m except R n and R n+1 is independently any one of hydrogen, an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms and an aryl group having 6 to 14 carbon atoms. stirring at least one compound I among compounds expressed by the following chemical formula and a hydrogenation reaction catalyst of 0.10 to 0.55 parts by weight based on 100 parts by weight of the compound I under a hydrogen atmosphere; and obtaining a metallocene compound containing at least one first compound among the compounds expressed by the following chemical formula in each of the chemical formula and the chemical formula, M is any one of titanium (Ti), zirconium (Zr) or hafnium (Hf); Q is any one of carbon, silicon (Si), germanium (Ge), or tin (Sn); X is independently any one of halogen, an alkyl group having 1 to 10 carbon atoms, and an alkenyl group having 2 to 10 carbon atoms; R 1, R 2, R 3, R 4, R 5, R 6, R 7, R 8, R 9, R 10, R 11, and R 12 satisfy the following (i) or (ii), and each of R 13 and R 14 is independently an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 14 carbon atoms. (i) each of R 1, R 2, R 3, R 4, R 5, R 6, R 7, R 8, R 9, R 10, R 11, and R 12 is independently any one of hydrogen, an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms and an aryl group having 6 to 14 carbon atoms.
