Sustainable hydrothermal self-assembly of hafnium–lignosulfonate nanohybrids for highly efficient reductive upgrading of 5-hydroxymethylfurfural
Lignosulfonate, a waste by-product from the paper industry, was simply assembled with HfCl4 to construct sustainable catalysts (Hf–LigS) for highly efficient reductive upgrading of 5-hydroxymethylfurfural.
