The safe and resource-efficient utilization of waste incineration fly ash (WIFA) has emerged as a pressing challenge in solid management. In this work, WIFA was used to prepare bifunctional catalyst (Metalsx/4@WIFA-S) for the production levulinic acid (LA) from glucose. yield LA 42.3% with water solvent. Moreover, adding 20% γ-valerolactone (GVL) system increased 50.7%. Reaction kinetics molecular dynamics simulations were applied elucidate mechanism by which solvent enhanced catalytic performance Metalsx/4@WIFA-S catalyst. Additionally, environmental risks preparation catalysts evaluated. dioxin decomposition rate calculated be 99.87%, effectively achieving detoxification concentration heavy metals hydrolysate complied emission standards, thereby reducing risk. This study confirms that ash-based are effective great potential application biomass catalysis.
