摘要：

Layered double hydroxide (LDH)-supported nano noble metal heterogeneous catalysts are synthesized by ion exchange of K2PtCl6, Na(2)pdCl(4) and impregnation of RhCl3-3H(2)O followed by reduction with H-2. The LDH-Rh, Pt, and I'd catalysts are tested in the enantioselective hydrogenation of ethyl pyruvate to ethyl lactate with very good yields and enantiomeric excess's (e.e.'s) of up to 72% were obtained with Pt. The catalyst was recovered and reused for several cycles with consistent activity.
