We have developed an electrocatalytic asymmetric hydrogenation reaction using a proton-exchange membrane (PEM) reactor that employs a polymer electrolyte fuel cell and industrial electrolysis technologies. Reasonable enantioselectivities and excellent current efficiencies were obtained in the asymmetric hydrogenation of α-phenylcinnamic acid under mild conditions without adding a supporting electrolyte. The current density was crucial to achieving the improved results observed.

用金鸡纳改性钯催化剂在PEM反应器中对α，β-不饱和酸进行电催化不对称加氢

我们已经开发了使用质子交换膜（PEM）反应器的电催化不对称氢化反应，该反应器采用了聚合物电解质燃料电池和工业电解技术。在温和条件下不添加辅助电解质的情况下，α-苯基肉桂酸的不对称氢化可获得合理的对映选择性和出色的电流效率。电流密度对于获得改善的结果至关重要。
