Abstract

Diatomite-supported Ni catalysts were synthesized via the simple immersion of diatomite in Ni(NO3)2 solution and the reduction with H2 in the tube furnace. The activity of synthesized catalysts was evaluated by the degradation of NO2. Various factors such as Ni amount, calcinations temperature, calcinations time, degradation reaction temperature were investigated in order to prepare the catalyst with the best activity for NO2 decomposition. The results indicated that Ni metal was highly dispersed onto the diatomite substrate and the best catalyst was the sample prepared with the Ni/diatomite ratio of 1 %, calcined at 500°C for 5 hours which showed the best NO2 conversion of 70% with NO2 fow rate of 0,067mmol/min for 0,25g catalyst.
