Valorisation of citrus waste for sustainable synthesis of carbon-supported copper nanoparticles active in CO 2 electroreduction (2024)
Journal Article

This study describes a microwave-assisted hydrothermal method to synthesise carbon-supported Cu-based electrocatalysts for CO2 conversion using citrus peels as both the carbon precursor and the reducing agent for Cu cations. XPS, TEM, and XRD analyse... Read More about Valorisation of citrus waste for sustainable synthesis of carbon-supported copper nanoparticles active in CO 2 electroreduction.

Alkali Metal Iridates as Oxygen Evolution Catalysts Via Thermal Transformation of Amorphous Iridium (oxy)hydroxides (2024)
Journal Article
Falsaperna, M., Arrigo, R., Marken, F., & Freakley, S. (in press). Alkali Metal Iridates as Oxygen Evolution Catalysts Via Thermal Transformation of Amorphous Iridium (oxy)hydroxides. ChemCatChem, Article e202401326. https://doi.org/10.1002/cctc.202401326

Achieving efficient water‐splitting under acidic conditions for hydrogen production is severely limited by the anodic oxygen evolution reaction (OER). Overcoming this obstacle is vital to realise effective electrolysers and deliver a hydrogen‐driven...

Investigation on the structure and performance of supported Ni nanoparticles for the hydrogenation of furfural (2024)
Journal Article

In this study, nickel nanoparticles were successfully synthesized using two methods: the hot‐injection method and a room temperature colloidal synthesis using dioctyl tartrate as a capping agent. Each approach yielded Ni nanoparticles with unique mor... Read More about Investigation on the structure and performance of supported Ni nanoparticles for the hydrogenation of furfural.

Synthesis and Characterisation of Metal Organic Frameworks for Use as Drug Delivery Systems in Neuroblastoma Therapy (2024)
Thesis

Gliotoxin, a secondary metabolite isolated from the fungi, Aspergillus fumigatus has
shown cytotoxic activity against neuroblastoma, a type of cancer accounting for 15%
of all childhood cancer-related deaths. But as with all other chemotherapeutic... Read More about Synthesis and Characterisation of Metal Organic Frameworks for Use as Drug Delivery Systems in Neuroblastoma Therapy.

Alkali Containing Layered Metal Oxides as Catalysts for the Oxygen Evolution Reaction (2024)

Assessment of the Degradation Mechanisms of Cu Electrodes during the CO (2023)
Journal Article

Catalyst degradation and product selectivity changes are two of the key challenges in the electrochemical reduction of CO on copper electrodes. Yet, these aspects are often overlooked. Here, we combine X-ray spectroscopy, electron microscopy, an... Read More about Assessment of the Degradation Mechanisms of Cu Electrodes during the CO.
