We showed selective CO2 reduction in an electrolyzer with a bipolar membrane, using Ni(cyclam) and its derivative.

3. Transport limited current: quantify gas transport to the catalyst using O2 reduction as a probe reaction
All these techniques complement each other and gives a deeper view into the state of the electrolyzer in action.

Twinned copper nanowires for CO2 reduction
New paper! led by Hsin-Yu (Terry) Chen who was a visiting student in our group

As an electrochemist, the coolest bit was how we demonstrated different ways to quantify the enhanced hydrophobicity of the system:
1. In-line gas pressure changes: indicate gas pathway blockage
2. Capacitance: measures degree of water penetration into the electrode pores

We won a prize!

CircularChem won an RSC Horizon prize. I was part of the team, as a postdoc with Alex Cowan, working on CO2 reduction to chemicals. I really enjoyed working with great people from different disciplines.

My first publication of 2025! But it's not in a chemistry journal...

It's a science fiction short story, titled "Starting anew under the starlight"

Out now in the online magazine Every Day Fiction

Cations can improve CO2 reduction on molecular catalysts!

In our paper, we show how cations (K+, Cs+) increase the selectivity of CoPc in a bipolar membrane cell

Surprisingly, cations only led to a small increase in *CO2 binding, which was one of the proposed mechanisms of selectivity enhancement.

Instead, the enhancement is due to suppression of H+ transport, observed as higher local pH.

Our review, with Clare Megarity, is out now in Curr. Opin. Electrochemistry.

We highlight recent work in electrochemical enzyme cascades , including new applications (measuring drug kinetics), ATP regeneration, and modelling of pore-confined cascades.
