摘要：Converting biomass into valuable aromatics is a desirable way to alleviate global energy crisis, but is currently challenged by massive energy consumption. Herein, a H2-free melting-catalysis strategy is proposed for direct converting glucose into aromatics under mild conditions by nano-sized mesoporous ZSM-5. We demonstrate that the melting of glucose promotes the accessibility to catalytic sites and enhances subsequent catalytic processes. The introduction of inter-crystalline mesopores facilitates diffusion of molecules, and the moderate acidity favors the deoxygenation of oxygenated intermediates, both of which promote aromatics formation. Consequently, 10-ZSM-5-80 with abundant inter-crystalline mesopores and optimum acidity achieves a maximum aromatics selectivity of 95.4 area% at 280 °C, of which 70.2% are monocyclic aromatic hydrocarbons. Furthermore, a possible mechanism is proposed based on experimental and online TG-FTIR-MS results. Our findings provide a new pathway for the selective generation of aromatics from glucose, which is expected to advance next-generation biomass utilization. ? 2022, The Authors. All rights reserved.
