Abstract: The present invention is catalyst capable of catalyzing the carbonylation of methanol into acetic acid and the carbonylation of methyl acetate into acetic anhydride in high speed, high selectivity and relatively mild condition. By means of design of catalyst molecule structure, non-rhodium metal with certain catalytic activity or obvious catalysis assisting activity on carbonylation reaction is introduced into catalyst with rhodium as active component to form new double active component catalyst. Of the catalyst, the positive ion active component may be square planar cis-bicarbonyl structure formed with organic compound or polymer containing N and O donor atom and Rh(I); and the negative ion active component may be coordination compound structure formed with organic carboxylic acid compound containing N and O donor atom and transition metal salt.
