Addressing electronic effects in the semi-hydrogenation of ethyne by InPd2 and intermetallic Ga–Pd compounds

[Display omitted] •InPd2 is synthesized and catalytically tested in semi-hydrogenation of acetylene.•InPd2 has superior stability and high selectivity to ethylene.•The catalytic activity is influenced by the position of d-band.•The selectivity is mainly governed by the active-site isolation. The int...
