“…The basic composition of an aqueous suspension for afterburner catalyst of exhaust gases was reasonable by the main requirements present to them in scientific and technical literature for ensuring effective work [1][2][3][4][5][6][7][8][9]. The oxidizing component for post-combustion exhaust gases has been selected palladium.…”

The boundary conditions of formation of hydroxides are determined by calculation of ion equilibrium with use of thermodynamic constants of metals For system "Pd(NO3)2 -Al2O3 -La2O3 -HAc -H2O". Possibility of decrease in dynamic viscosity of the "Pd(NO3)2 -Al2O3 -La2O3 -HAc -H2O", suspension having pH = 3 at addition of 1% of an aqueous solution is experimentally shown cation-active surfactant at 1.74 time: with 850.62 to 488.95 mPa·s. The morphology of particles of suspension before and after the addition in it surfactant cation-active Praestol 655 FC is investigated.

Methane is an important gas for domestic and industrial applications and its source is mainly coalmines. Since methane is extremely inflammable in the coalmine atmosphere, it is essential to develop a reliable and relatively inexpensive chemical gas sensor to detect this inflammable gas below its explosion amount in air. The metal oxides have been proved to be potential materials for the development of commercial gas sensors. The functional properties of the metal oxide-based gas sensors can be improved not only by tailoring the crystal size of metal oxides but also by incorporating the noble metal catalyst on nanocrystalline metal oxide matrix. It was observed that the surface modification of nanocrystalline metal oxide thin films by noble metal sensitizers and the use of a noble metal catalytic contact as electrode reduce the operating temperatures appreciably and improve the sensing properties. This review article concentrates on the nanocrystalline metal oxide methane sensors and the role of noble metals on the sensing properties.

Total Oxidation of Propane by using Platinum‐Group‐Metal Catalysts Recovered from Fuel‐Cell Recycling

Platinum‐group‐metal materials were recovered from fuel cells and studied as catalysts for the total oxidation of propane as model reaction. Therefore a representative number of metal‐foam catalysts containing platinum, palladium, and ruthenium in certain ratios were prepared and investigated. Interestingly, particularly active catalysts were observed with a high fraction of one metal and small amounts of the other two metals. This suggests a principal trend for preparing efficient catalysts using ternary‐precious‐metal systems. For the recycling of fuel‐cell compounds the composition of the material could be varied by the substitution or addition of appropriate amounts of precious metals to achieve the highest performance.
