“…The catalysts-neutralizers of the exhaust (catalytic converter, an afterburner) are the mandatory option for all cars in the developed countries. Today, the monolithic metal blocks are considered as the most appropriate catalysts used for the solution of environmental problems [13][14][15][16][17]. High heat conductivity of metal carriers provides the good thermoregulation preventing an overheat of catalysts and interfacing constructional details.…”

“…It was found that the most stable appeared the catalysts obtained from acetates Pt, less stable -on basis palladium.. High thermal stability of the oxide washcoat is provided with introduction to it of the modifying additives. For example, into the alumina washcoat are introduced cations of cerium, zirconium, lanthanum, which do not only stabilize γ-Al 2 O 3 phase, but also provide resistance to poisons or sintering of Pt, Pd, Rh-active components of the catalysts [25][26][27] +. Activity of Pt-Cu catalysts on the zeolite-containing washcoats NaY, ZSM-5 and their hydrogen forms was studied.…”

Catalysts on the metal block carriers for decrease exhaust gases of motor transport were synthesized and tested. Stability of the carrier and the active phase of the catalysts to poisons SO 2 and oxygen in the processes of cleaning of exhaust gases was studied. In the presence of 3% oxygen, the catalyst activity was considerably increased, especially for Co+Mn and Ni+Mn, but increase in content of oxygen to 10% reduced effectiveness of catalysts. Nickel-manganese catalyst promoted with 0.1 wt.% Pt was the most stable against oxygen influence. The activity of catalysts based on Pt, Pt+Pd, Pd in presence of SO 2 decreased at low test temperatures, but after calcination at 500°C with air blowing for 2 h activity of Pt catalyst was almost returned and reached 80%. After the tests of the catalysts at the stand on the basis of the diesel generator (5GF-LDE with power of 5 kVA) degree of conversion of CO was 99.6%, hydrocarbons-80.7 %, nitrogen oxides -60-61.9%.

“…The active intermediate compounds formed on the surface of the catalysts. Between the adsorbed molecules of NO and active intermediate compounds, a synergism interaction is possible which would result in the formation of N 2 and CO 2 [38,[43][44][45][46][47]. activity and thermal stability of the catalysts on the reduction of NO with CO as reducing agent were evaluated.…”

Copper iron composite oxides (CuO/Fe 2 O 3) and copper cobalt composite oxides (CuO/Co 3 O 4) for the catalytic reduction of NO with CO at low temperature were prepared by co-precipitation. The catalytic activity and thermal stability of the catalysts were evaluated by a microreactor-GC system. The 100% conversion temperatures of NO are 80 • C for CuO/Fe 2 O 3 and 90 • C for CuO/Co 3 O 4. The catalysts possess high catalytic activity and favorable thermal stability for NO reduction with CO in a wide temperature range and long time range. A systematic study of the molar ratios of the reactants, the volume of NaOH, aging time, and calcination temperature/time was carried out to investigate the influence preparation conditions on the catalytic activity of the catalysts.
