Biomass-derived activated carbon with simultaneously enhanced CO2 uptake for both pre and post combustion capture applications (2015)
Journal Article
Coromina, H. M., Walsh, D. A., & Mokaya, R. (2015). Biomass-derived activated carbon with simultaneously enhanced CO2 uptake for both pre and post combustion capture applications. Journal of Materials Chemistry A, 4(1), https://doi.org/10.1039/C5TA09202G

We report on the synthesis and CO2 uptake capabilities of a series of activated carbons derived from biomass raw materials, Jujun grass and Camellia japonica. The carbons were prepared via hydrothermal carbonization of the raw materials, which yielde...

Synergistic catalyst-support interactions in a graphene-Mn3O4 electrocatalyst for vanadium redox flow batteries (2015)
Journal Article
Ejigu, A., Edwards, M., & Walsh, D. A. (2015). Synergistic catalyst-support interactions in a graphene-Mn3O4 electrocatalyst for vanadium redox flow batteries. ACS Catalysis, 5(12), https://doi.org/10.1021/acscatal.5b01973

The development of vanadium redox flow batteries (VRFBs) is partly limited by the sluggishness of the electrochemical reactions at conventional carbon-based electrodes. The VO2+/VO2+ redox reaction is particularly sluggish and improvements in battery...

Room temperature ionic liquid electrolytes for redox flow batteries (2015)
Journal Article
Ejigu, A., Greatorex-Davies, P., & Walsh, D. A. (2015). Room temperature ionic liquid electrolytes for redox flow batteries. Electrochemistry Communications, 54, https://doi.org/10.1016/j.elecom.2015.01.016

Redox flow batteries (RFBs) usually contain aqueous or organic electrolytes. The aim of this communication is to explore the suitability of room temperature ionic liquids (RTILs) as solvents for RFBs containing metal complexes. Towards this aim, the...

Scanning electrochemical microscopy at thermal sprayed anti-corrosion coatings: effect of thermal spraying on heterogeneous electron transfer kinetics (2011)
Journal Article
Niaz, A., Boatwright, A., Voisey, K., & Walsh, D. A. (2011). Scanning electrochemical microscopy at thermal sprayed anti-corrosion coatings: effect of thermal spraying on heterogeneous electron transfer kinetics. Journal of Electroanalytical Chemistry, 657(1-2), https://doi.org/10.1016/j.jelechem.2011.03.009

The effect of thermal spraying on the electrochemical activity of an anti-corrosion superalloy was studied quantitatively using scanning electrochemical microscopy (SECM). The superalloy used was Inconel 625 (a Ni base superalloy) and thin coatings o...
