and sorbitol, reinforces the adsorption of polyol radical intermediates, and decreases the energy barrier for hydroxyl group elimination. The active centers of Nb-N preferentially interact with hydroxyl lone-pair electrons, effectively polarizing C-O bonds to initiate stepwise cascade dehydration. This work provides fundamental insights into the design of nanocatalysts for biomass conversion, establishing a new paradigm for functional catalytic architectures towards various applications.
