A catalyst for ultra-deep desulfurization of diesel via oxidative distillation is an amphiphilic oxidative catalyst, which is expressed as Qm[XMnOq], wherein 1≦̸m≦̸12; 9≦̸n≦̸18; 34≦̸q≦̸62; Q is a quaternary ammonium cation; X is P, Si, As or B; and M is Mo) or W. A desulfurization method comprises a) mixing well a diesel, the amphiphilic catalyst, and hydrogen peroxide, reacting for 10-300 minutes at ambient temperature and normal pressure, transforming the sulfur-containing compounds in the diesel into sulfone to obtain an oxidized diesel; b) distilling the oxidized diesel obtained in step a) under reduced pressure to obtain the ultra-low sulfur diesel having a sulfur content of less than 10 ppm; and c) separating and recovering the catalyst and sulfone.
