Abstract	Describes how the directional self-assembly of exfoliated layered europium hydroxide (LEuH) nanosheets and europium-containing heteropolytungstate anions was accomplished by mixing an LEuH colloidal solution and a Na9EuW10O36·32H2O (EuW10) solution at room temperature. This led to the formation of a new inorganic/inorganic hybrid material, Eu2(OH)5(EuW10O36)0.11·5.5H2O (LEuH-EuW10). Employment of LEuH-EuW10 in extractive catalytic oxidative desulfurization (ECODS) demonstrated that highly efficient and selective deep desulfurization can be achieved in just 15 min under mild conditions. A maximum turnover number (TON) of around 1600 was achieved. The catalyst can be recycled and reused at least 10 times with minimal loss of catalytic efficiency.
