Synergetic Effect Of H+ Adsorption And Ethylene Functional Groups Of Covalent Organic Frameworks On The Co2 Photoreduction In Aqueous Solution

We prepare a novel COF for CO(2)photoreduction with 99.9% CO selectivity in aqueous solution without a cocatalyst. DFT shows that the preferential adsorption of H(+)on the COF results in increased CO(2)adsorption energy providing an anchoring site of CO2, and with the cooperation of an ethylene group, CO(2)reduction is triggered.
