Impact of Incorporation of Active Nanoporous Components or Their Precursors in a CuAlO/CuAl Ceramometal Skeleton on the Properties in the Low-Temperature Water-Gas Shift Reaction
Abstract:Enhanced activity in low-temperature
water-gas shift (LT-WGS) reaction
of some ceramometal catalysts compared to conventional Cu–Zn–Al
oxide catalyst was demonstrated. Porous ceramometals were synthesized
from powdered CuAl alloys prepared by mechanical alloying with the
addition of either CuAl
exp
powders produced by current
spark explosion of Cu+Al wires or CuZnAl oxide obtained by coprecipitation.
Their structural, microstructural, and textural characteristics were
examined by means o… Show more
“…15,16 The method of incorporating the active Co-component into a ceramo-metal matrix allows one to solve the problems and makes it possible to obtain catalysts with high mechanical strength, high thermal conductivity and a developed porous structure. The same method has been successfully applied to obtain Cu-based WGSR catalysts [17][18][19] and Fe-based catalysts for the Fischer-Tropsch synthesis. 20,21 Both these composite catalysts have shown promise for catalytic applications.…”
We investigated the possibility of synthesizing Co nanoparticles in CoZrnH/AlOx(OH)y/Al ceramic-metal catalysts and controlling catalytic properties of these nanoparticles in the syngas conversion by changing the Co/Zr ratio. The CoZr...
