A high-temperature catalytic material and a method for producing the same are disclosed. The high-temperature catalytic material is obtained by subjecting a mixture of gibbsite and boehmite in a desired weight ratio to a single dry thermal treatment in the air, without alkaline or hydrothermal treatment, so as to obtain multiphase alumina powder as the high-temperature catalytic material. The multiphase alumina powder applied in the high-temperature catalytic material can raise the temperature of phase transformation, maintain its high specific surface area when suffering high temperatures for a long time, prolongs its lifetime, and reduces the usage of noble metals, resulting in great reduction of cost.
