Under UV irradiation, the hydrogenation of olefins can be completed under normal temperature and pressure conditions. The reaction rules of different cobalt salt catalysts and the influence of acidity and basicity on the reaction were studied systematically. It was found that sodium acetate can greatly improve the selectivity and yield of the reaction. The primary mechanism of the action of sodium acetate is proposed, that is, the adjustment of the pH value of the reaction system and the interaction between sodium acetate and the catalyst.
