The invention discloses a preparation method of a noble metal and transition metal catalyst. The catalyst is mainly composed of a transition metal oxide carrier and precious metal and transition metal loaded on the transition metal oxide carrier, the precious metal is at least one of Pt, Pd, Ru and Rh or oxides thereof, and the transition metal is at least one of Nb, Co, Mn, Zr, Cu and Ce oxides. The titanium dioxide loaded noble metal and transition metal catalyst is simple in preparation process, does not generate secondary pollution, efficiently eliminates oxygen in fuel steam at low temperature, and has high catalytic activity and stability; the precious metal component has strong binding force with titanium dioxide, is not easy to fall off in the flight process of an aircraft, and is especially suitable for efficient oxygen consumption of an aircraft inerting system.
