Progress in catalysts for selective hydrogenation of citral to nerol and geraniol

In this paper,the development of the catalysts for the citral selective hydrogenation system,the influencing factors on the performance of the catalysts and the mechanism of citral hydrogenation reaction are reviewed,combined with the most novel advances in this field.It is point out that the methods for the preparation of active agent,carrier and assistants are the key to obtain the catalysts with high selectivity and acitivity for citral hydrogenation.
