heal.abstract	A set of rhodium catalysts supported on γ-alumina was prepared using the wet impregnation procedure. The catalysts were tested under steady-state CO-NO reaction. A kinetic study was performed so as to simulate the experimental data to a kinetic expression. Inhibition effects were observed dictating an expression having a denominator in terms of NO concentration. The pH of the impregnation solution was the crucial variable in the preparation of four catalysts of w = 0.22-0.24% Rh at initial pH ranging from 1 to 4.6. The impregnant pH influenced the catalytic performance: catalysts prepared under basic conditions showed a higher catalytic activity than those prepared under acidic conditions.	en
