Understanding the structure-activity/selectivity relationships at the molecular scale is of significant importance in assisting the development of new catalytic processes in microstructured reactors. The selective hydrogenation of 2-methyl-3-butyne-2-ol on a series of well-characterized mesostructured titania supported bimetallic PdZn thin films has been studied to clarify key factors responsible for high selectivity to the semihydrogenated product. The highest selectivity towards the semihydrogenated product (2-methyl-3-butene-2-ol, MBE) over Pd/Ti02 was 83%. The bimetallic PdZn catalyst with a Zn/Pd molar ratio of 3 demonstrated the highest selectivity towards MBE of 90% which was achieved at 60 °C with a H2 partial pressure of 0.7. Addition of a base either on the surface of the catalyst or in the liquid phase further improved selectivity to MBE towards 98%.
