Popis:	This study has shown that the deposition of iron salts (iron acetylacetonate) in extremely low concentrations (0.1 wt %) on lignin leads to an abrupt increase in the ability of lignin to absorb 1 kW microwave radiation and lignin conversion to a hydrogen-containing gas with a hydrogen recovery of up to 90% in terms of hydrogen contained in lignin. It has been found that the deposition of metals (Fe and Ni) on lignin makes it possible to directionally change the selectivity of the lignin degradation process under the action of microwave radiation; therefore, this process can be classified as a plasma catalytic degradation. The results can be used to minimize the amount of the catalyst and propose an efficient method to produce hydrogen from lignin waste.
