Highly effective non-noble MnO2 catalysts for 5-hydroxymethylfurfural oxidation to 2,5-furandicarboxylic acid

ChemSusChem. 2024 Mar 5:e202400115. doi: 10.1002/cssc.202400115. Online ahead of print.ABSTRACTNoble metal-free catalyst or catalytic oxidation of 5-hydroxymethylfurfural into 2,5-furandicarboxylic acid are proposed in this study as a proposal to solve one of the great disadvantages of this reaction of using preferably noble metal-based catalysts. The catalytic activity of six MnO2 crystal structures is studied as alternative. The obtained results showed a strong connection between catalytic activity the type of MnO2 structure organization and redox behavior. Among all tested catalysts, ε-MnO2 showed the best performance with an excellent yield of 74% of 2,5-furandicarboxylic acid at full -hydroxymethylfurfural conversion.PMID:38442078 | DOI:10.1002/cssc.202400115
