Semi-Encapsulated PdRh Alloy Heterojunction for the Selectively Catalytic Hydrogenation of Nitrophenylacetylene to Nitrostyrene Wenhui Zhang, Yiming Wang, Kelong Ding, Hong Li, Zejun Sun, Zenan Hu and Hongbin Sun Abstract Semi-hydrogenation usually requires an effective catalyst to ensure selectivity, especially when reducible groups coexist in a molecule. Pd is widely used in the semi-hydrogenation of alkynes to synthesize alkenes, but the selectivity control is still challenging.
