A thermal barrier coating and a cold-wall reactor including the coating are provided. A second ceramic layer is sandwiched between the conventional two-layer structures of the thermal barrier coating. The second ceramic layer is made of aluminum oxide stabilized zirconium oxide and the content of aluminum oxide does not exceed 30 wt %. The zirconium oxide in the first and second ceramic layer has a tetragonal crystal structure. A cold-wall reactor formed by applying the thermal barrier coating provides advantageous steel hydrogen corrosion resistance in ultra-high temperature. The effective volume of the hydrogenation reactor is fully used, overcoming the problem that the thermal insulation liner is easily damaged and causes local overheating of the reactor wall, as well as eliminating potential safety hazards of reactor wall local stress concentration caused by expansion and contraction of the liner cylinder attachment member.
