M. Hietikko scite author profile

Effects of phosphorus poisoning on the activity of powdered exhaust gas catalyst components containing different oxides and platinum were studied. The decrease in the catalytic activity was associated with phosphorus compounds formed with the catalyst components. The poisoned samples were studied using XRD and FTIR-ATR techniques. The same compounds, phosphates of cerium, zirconium, aluminium and titanium, have also been detected in vehicle aged diesel catalyst converters.
