Confined MnO Nanoparticles Within Thin Carbon Tubes: Sustained Catalysts for the Synthesis of Biomass‐Derived Diol Polymer Platforms

Abstract This work suggests a synthetic strategy for the development of durable metal oxide heterogeneous nanocatalysts used for the conversion of biomass into polymer platforms. MnO₂ nanowires are coated with conjugated microporous polymers. Successive calcination under argon results in the generation of MnO nanoparticles confined within carbon tubes (CTs). The resultant MnO@CTs show good catalytic performance in the transesterification of dimethyl furan dicarboxylate with various diols to polymer platforms, furan diols. While commercial MnO nanoparticles show poor durability, due to their facile aggregation, the optimal MnO@CT‐1 shows excellent recyclability and durability.
