Abstract
The rigid structure of cellulose renders a challenge for the efficient transformation of cellulose into valuable chemicals under mild conditions. Here, we report a multifunctional catalyst (Ru/HY-SO3H) for the selective cellulose conversion to 5-hydroxymethylfurfural (HMF) with a yield of 48.4% in a biphasic medium (ionic liquid/methyl isobutyl ketone) at a relatively low temperature (120 °C) and light illumination. The high yield of HMF from direct cellulose transformation is attributed to the cooperative effect of Ru particles and acidic sites. Ru supported on zeolite Y generates the surface plasmon resonance effect to enhance the catalytic activity via light energy harvesting and provides more acid sites to enhance cellulose hydrolysis. The biphasic system is found to facilitate the production of HMF by protecting it from undergoing side reactions. Our work demonstrates a feasible and sustainable way to efficiently produce high value-added chemicals from biomass conversion driven by solar energy under mild conditions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
