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.

    本发明公开了一种贵金属和过渡金属催化剂的制备方法。该催化剂主要由过渡金属氧化物载体及其负载的贵金属和过渡金属构成,其中贵金属为Pt、Pd、Ru、Rh金属或其氧化物的至少一种,过渡金属为Nb、Co、Mn、Zr、Cu、Ce氧化物的至少一种。二氧化钛负载的贵金属和过渡金属催化剂制备过程简单不产生二次污染,在低温下高效地消除燃料蒸汽中的氧气,具有高催化活性和稳定性;贵金属组分与二氧化钛结合力强,在飞机飞行过程中,不易脱落,特别适用于飞机惰化系统高效耗氧。
