The research results were published in the Materials magazine, which is issued by the McGill University (Montreal) since 2008.
The research was called to simplify production of the catalysts, which accelerate a reaction of hydrogen and carbon oxide, leading to generation of syngas and spirits for chemical industry. “Our catalysts are 3-D alloys with porous surface and Nano-size grains, which form foamy particles. Due to such morphology and synergetic interaction between cobalt and nickel, the catalysts feature more intensive interaction with the CO2 molecules and higher stability in comparison to commercial coating peers”,– the TASS quotes Sergey Roslyakov, the senior research fellow from the NRTU ‘MISiS.
According to him, the experiment’s distinctive feature was fast and simple material synthesis by way of combustion: in order to heat up a small piece of a sample, the researchers just applied insignificant energy, after which the reaction went in self-sustained mode without additional energy input. The catalyst’s composition that completely consists of metallic alloy rendered much higher heat conductivity compared to ceramic headers.
“We simplified the materials preparation method, avoiding lengthy and non-trivial stages of melting, spraying, purification, application of active components onto structure-forming header and others. Despite of simplicity of the synthesis process and the catalyst’s composition, we acquired competitive technology of catalytic conversion of carbon oxide”, – said S.Roslyakov.
