Pd₃Sn nanoparticles on TiO₂ and ZnO supports as catalysts for semi-hydrogenation : synthesis and catalytic performance. Applied catalysis. A, General, 544, 40-45. https://doi.org/10.1016/j.apcata.2017.07.005

The two catalysts Pd₃Sn/TiO₂and Pd3Sn/ZnO were prepared via a one-pot procedure based on the “polyol method” with the addition of a capping agent (polyvinylpyrrolidone) to control the particle size distribution. The same procedure was used to prepare... Read More

Particles at oil–air surfaces : powdered oil, liquid oil marbles, and oil foam (2015)
Journal Article
Binks, B. P., Johnston, S. K., Sekine, T., & Tyowua, A. T. (2015). Particles at oil–air surfaces : powdered oil, liquid oil marbles, and oil foam. ACS applied materials & interfaces, 7(26), (14328-14337). doi:10.1021/acsami.5b02890. ISSN 1944-8244

The type of material stabilized by four kinds of fluorinated particles (sericite and bentonite platelet clays and spherical zinc oxide) in air–oil mixtures has been investigated. It depends on the particle wettability and the degree of shear. Upon vi... Read More

Palladium-bismuth intermetallic and surface-poisoned catalysts for the semi-hydrogenation of 2-methyl-3-butyn-2-ol (2015)
Journal Article
Cherkasov, N., Ibhadon, A. O., McCue, A. J., Anderson, J. A., & Johnston, S. K. (2015). Palladium-bismuth intermetallic and surface-poisoned catalysts for the semi-hydrogenation of 2-methyl-3-butyn-2-ol. Applied catalysis. A, General, 497, 22-30. https://doi.org/10.1016/j.apcata.2015.02.038

The effects of poisoning of Pd catalysts with Bi and annealing in a polyol (ethylene glycol) were studied on the semi-hydrogenation of 2-methyl-3-butyn-2-ol (MBY). An increase in the Pd:Bi ratio from 7 to 1 in the Bi-poisoned catalysts decreased the... Read More
