Using the diagram below,
i) State both the galvanic and electrolytic reactions when CH3OH/CO2 and H2O/O2 half cell reactions are combined.
ii) What is the minimum theoretical voltage for the electrolytic cell to work?
iii) Choose one semiconductor material (no heterojunction, no co-catalyst) that could be used as a photocatalyst for this reaction. Explain.
