As a summary, a novel strategy to prepare Zrꢀcontaining catalysts
using low rank coal derived humic acids (HAs) as raw materials was
proposed. Both commercial HAs and HAs extracted directly from
low rank lignite were used to synthesize ZrꢀHAs catalysts. The
catalyst from commercial HAs (ZrꢀHAsC) was proved to be highly
efficient for the MPV reactions of various carboxyl compounds with
different structures. HAs extracted from lignite could be directly
applied into the preparation of the catalyst with no need of further
separation or treatment, and the obtained catalyst (ZrꢀHAsE) was
identified to be efficient for the conversion of furfuryl into FA with
excellent stability. Using HAs as the raw materials to synthesize
catalysts is believed to be an effective approach for both valueꢀadded
utilization of lignite derivatives and the conversion of biomass
resources. The novel catalyst may find potential applications in
catalytic fields with the advantages of the abundance of HAs, the
low cost of Zr metal, and the excellent performance.
