%X The catalytic reduction of nitric oxide by carbon monoxide over cobalt tetraphenylporphyrin supported on titanium dioxide (Co-TPP/TiO2) has been investigated. Co-TPP/TiO2 pretreated by evacuation at 270℃ exhibited a remarkable activity. The kinetic equation for the reduction of nitric oxide by carbon monoxide in the reaction temperature ranging from 80 to 150℃ (v=kPNO 0.56Pco 0.41) suggested that the reaction can be assumed to occur via a surface reaction of the Langmuir-Hinshelwood model between nitric oxide and carbon monoxide adsorbed on the central metal ion of Co-TPP. Experimental results indicated that the reduction of nitric oxide and formation of molecular nitrogen took place simultaneously during initial stage of the reaction. The apparent activation energy was calculated to be 30.8 kJ/mol.
