Synthesis of Biomass‐Based MIL‐101(Cr)@hydrochar for Efficient Conversion of Xylose to Furfural: Effects of Physicochemical Properties and Biomass Types

active centers, enabled by synergistic MOF-templated modification engineering and biomass hydrothermal carbonization. Moreover, the correlation between the physicochemical properties and catalytic performance of modified hydrochar was analyzed. Notably, biomass feedstocks with low ash content and high nitrogen content can yield modified hydrochar with more acidic active sites, which exhibits superior catalytic activity. This study provides new ideas for the high-value utilization of waste biomass.
