• H2: GC-TCD • CO, CH4: GC-FID

Analysis method:

Gas phase products:

Liquid phase products: • HCOOH: HPLC

CO2 reduction is realized without extra power input except for illumination with light.

-0.16V -1.07VPotential of Cu electrode:

Faradic efficiency for HCOOH ：3.2%

Preliminary proposal

Target ：

Gas phase products: H2, CO, CH4, CO2, N2

Liquid phase products: HCOOH ， CH3OH

Method:

Gas phase products: GC

Liquid phase products: GC(for HCOOH),HPLC (for CH3OH)

Preliminary proposal

HPLC

Different from GC:

• Free of the limitation of Volatility and thermal stability• A broad range of Objects: GC—20% of Organics HPLC—80% of Organics• Mobile phase ： GC— inert gas, no interact with Component HPLC—liquid, have interact with Component, so the Polarity, PH value, Composition of mobile liquid is important for Separate• Temperature and pressure: GC—add the temperature HPLC—room temperature high pressure, for the Narrower peaks because of the high viscosity

Different solubility in Two kinds of Solvent, just like L-L extraction.

Which kind? SEM?

How? Spin coating?
