Layered double hydroxides (LDHs), especially high-entropy LDHs (HE-LDHs), have gained increasing attention. However, HE-LDHs often possess poor thermal stability, restricting their applications in thermo-catalysis. Herein, a novel complexing nucleation method is proposed for engineering with enhanced stability. This approach precisely controls the of metal ions different solubility products, achieving homogeneous and effectively mitigating phase segregation transformation at elevated temperatures. The prepared HE-LDH sample demonstrated exceptional stability temperatures up to 300 °C, outperforming all previously reported LDHs. Importantly, these preserve both Lewis Brønsted acidic sites, enabling 100% removal aromatic sulfides alkaline nitrogen compounds from fuel oils thermo-catalytic oxidation reactions. Experimental characterization findings reveal that metal-hydroxide bonds are strengthened by associated hydroxyl groups, inducing negative expansion augmenting presence thereby ensuring structural enhancing catalytic activity. study not only proposes strategy remarkable but also highlights potential
