A group of Russian scientists has developed a catalyst based on plant waste that solves the problem of "dead metal" - a phenomenon that reduces the efficiency of traditional palladium catalysts based on carbon supports. Researchers from the University of MISIS, the N.D. Zelinsky Institute of Organic Chemistry, Skoltech and other leading scientific centers used liquid humins - a by-product of the production of furan compounds from plant biomass.
We have proposed not just a solution to one of the problems of heterogeneous catalysis, but an approach that turns industrial waste into valuable renewable raw materials. This is another step towards sustainable development and a circular economy.
By mixing humins with nitrogen-containing melamine and subjecting them to heat treatment, scientists obtained a carbon material with low porosity and high nitrogen content. This structure ensured a uniform distribution of palladium nanoparticles, preventing them from being blocked in the pores of the support, which ensured the availability of the active metal and increased efficiency. As a result, the new catalyst showed high activity and stability in reactions that are critical for the pharmaceutical and chemical industries.
