Our original conclusions

RB’s MA

At reductive potential (−1.06 V), CuPc is reduced to Cu NPs which are the active catalyst for CO2 reduction to CH4.

Agrees with us on what happens at the reductive potential.

After release of the reductive potential, (at least a large part of) Cu NPs are converted back to CuPc.

After release of the reductive potential, All Cu NPs are oxidized to Cu2+ and leach into the electrolyte, no regeneration of CuPc.
