Preprint / Working Paper
Thangamuthu, M., Burwell, T., Aliev, G., Ghaderzadeh, S., Kohlrausch, E., Chen, Y., …Khlobystov, A. Direct Deposition of Copper Atoms onto Graphitic Step Edges Lowers Overpotential and Improves Selectivity of Electrocatalytic CO2 Reduction

Minimizing our reliance on bulk precious metals is to increase the fraction of surface atoms and improve the metal-support interface. In this work, we employ a solvent/ligand/counterion-free method to deposit copper in the atomic form directly onto a...

Selective Excitation of Pd-decorated Titania Enables Consecutive C−C Couplings and Hydrogenations under Ambient Conditions (2023)
Journal Article
Whitehead, R. Z., Norman, L. T., Cull, W. J., Fernandes, J. A., & Lanterna, A. E. (2023). Selective Excitation of Pd-decorated Titania Enables Consecutive C−C Couplings and Hydrogenations under Ambient Conditions. ChemCatChem, 15(21), Article e202300528. https://doi.org/10.1002/cctc.202300528

Here, we discovered that Pd decorated TiO2 (Pd@TiO2) enables consecutive photocatalytic Sonogashira C−C coupling and hydrogenation steps by simply adjusting the excitation conditions of the reaction. We demonstrated that by-products containing iodine... Read More about Selective Excitation of Pd-decorated Titania Enables Consecutive C−C Couplings and Hydrogenations under Ambient Conditions.

Unravelling synergistic effects in bi-metallic catalysts: deceleration of palladium–gold nanoparticle coarsening in the hydrogenation of cinnamaldehyde (2023)
Journal Article
Pinto, J., Weilhard, A., Norman, L. T., Lodge, R. W., Rogers, D. M., Gual, A., …Alves Fernandes, J. (2023). Unravelling synergistic effects in bi-metallic catalysts: deceleration of palladium–gold nanoparticle coarsening in the hydrogenation of cinnamaldehyde. Catalysis Science and Technology, https://doi.org/10.1039/d3cy00289f

In this work, we demonstrate that the synergistic effect of PdAu nanoparticles (NPs) in hydrogenation reactions is not only related to high activity but also to their stability when compared to Pd mono-metallic NPs. To demonstrate this, a series of m...

Synthesis of ultrathin rhenium disulfide nanoribbons using nano test tubes (2021)
Journal Article
Norman, L. T., Biskupek, J., Rance, G. A., Stoppiello, C. T., Kaiser, U., & Khlobystov, A. N. (2022). Synthesis of ultrathin rhenium disulfide nanoribbons using nano test tubes. Nano Research, 15(2), 1282-1287. https://doi.org/10.1007/s12274-021-3650-2

The synthesis of ultrathin rhenium disulfide (ReS2) nanoribbons within single-walled carbon nanotubes (SWNTs) has been established. Dirhenium decacarbonyl complex is encapsulated into the SWNTs to provide a source of confined rhenium atoms, which rea...
