Catalytic methylation utilising methanol as a sustainable C1 building block and hydrogen source continues to attract attention due to its atom-economical, cost-effective, and simple one-pot method. So far, research on...

We established a novel heterogeneous catalytic system for the semi‐hydrogenation of diphenylacetylene through hydrogen transfer from biomass as an abundant and cheap hydrogen source using a bimetallic PdCuFe3O4 nanoparticle catalyst. A wide range of carbohydrates from biomass sources were successfully utilized in the selective semi‐hydrogenation of diphenylacethylene in 2‐butanone/water.
