    • A chromium-based catalyst system comprising a transition metal or transition metal precursor, a cocatalyst, and a ligand of P-C-C-P frame structure is provided, and a method for preparing 1-octene at high activity and high selectivity while maintaining reaction activity stably by using the chromium-based catalyst system is provided. An ethylene tetramerization catalyst system comprises a transition metal or a transition metal precursor, a cocatalyst, and a ligand of P-C-C-P frame structure represented by the formula 1, where R^1, R^2, R^3 and R^4 are independently a hydrocarbyl, a substituted hydrocarbyl, a hetero-hydrocarbyl, or a substituted hetero-hydrocarbyl, the R^1, R^2, R^3 and R^4 do not have substituents on atoms adjacent atoms bonded to P, and R^5 and R^6 are a hydrocarbyl or a substituted hydrocarbyl except hydrogen. The ethylene tetramerization catalyst system comprises multiple ligands of P-C-C-P frame structure in which two or more ligands of P-C-C-P frame structure are bonded. A method for preparing 1-octene comprises tetramerizing ethylene using the ethylene tetramerization catalyst system. Further, the transition metal or the transition metal precursor is chrome or chrome precusor, and the cocatalyst is methylaluminoxane or ethylaluminoxane.
