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.

Interfacial chemistry in the electrocatalytic hydrogenation of CO2 over C-Supported Cu-Based systems (2023)
Journal Article

Operando soft and hard X-ray spectroscopic techniques were used in combination with plane-wave density functional theory (DFT) simulations to rationalize the enhanced activities of Zn-containing Cu nanostructured electrocatalysts in the electrocataly...

Insights by in-situ studies on the nature of highly-active hydrotalcite-based Ni-Fe catalysts for CO2 methanation (2023)
Journal Article

Designing CO2 methanation catalysts that meet industrial requirements is still challenging. We report Ni-Fe hydrotalcite-derived catalysts with a wide range of Ni and Mg loadings showing that an optimised composition with Ni0.4 gives a very high CO2...

Lithium-Directed Transformation of Amorphous Iridium (Oxy)hydroxides To Produce Active Water Oxidation Catalysts (2023)
Journal Article

The oxygen evolution reaction (OER) is crucial to future energy systems based on water electrolysis. Iridium oxides are promising catalysts due to their resistance to corrosion under acidic and oxidizing conditions. Highly active iridium (oxy)hydroxi...

Orange peel biomass‐derived carbon supported Cu electrocatalysts active in the CO2 ‐ reduction to formic acid (2023)
Journal Article
Miah, T., Demoro, P., Nduka, I., De Luca, F., Abate, S., & Arrigo, R. (2023). Orange peel biomass‐derived carbon supported Cu electrocatalysts active in the CO2 ‐ reduction to formic acid. ChemPhysChem, https://doi.org/10.1002/cphc.202200589

We report a green, wet chemistry approach towards the production of C‐supported Cu electrocatalysts active in the CO2 reduction to formic acid. We use citrus peels as a C support precursor and as a source of reducing agents for the Cu cations. We sho...
