| Abstract | The selective oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) has attracted much attention recently, as FDCA could be used as a polymer precursor to produce recyclable bio-based polymers. But most studies focused on the design of noble metal catalysts for the efficient oxidation of HMF to FDCA, here, non-noble metal catalysts, MnOx–CeO2 mixed oxides, were prepared by a co-precipitation method and used in the direct aerobic oxidation of HMF to FDCA. As high as 91% yield of FDCA was achieved over the MC-6 (Mn/Ce = 6) catalyst and the catalyst can be reused five times without much loss of catalytic activity, this is the best result for non-noble metal catalyzed HMF oxidation to FDCA in the aqueous phase. Structural analysis revealed that surface Mn4+ ions are the active sites and play key roles for the oxidation of HMF in the absence of noble metals. In addition, the reaction mechanism over the MnOx–CeO2 catalyst was also proposed based on the synergistic interaction between Mn and Ce oxides. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
