Can anyone advise me regarding selectivity for only one product e.g. CH4, CO or CH3OH in the photoreduction of CO2?

Why would some photocatalyst reduce CO2 to CH4 only even though its conduction band is more negative than the reduction potential of CO2/CH4, CO2/CO or CO2/CH3OH? What is the reason for this? Why...
