| 제목 | N-doped graphene oxide enfolded reduced titania for highly stable andselective gas-phase photocatalytic CO2 reduction into CH4 |
| 초록 | A desire for renewable alternatives to fossil fuelscan be achieved by utilizing CO2, H2O, and solar energyto generate solar fuels. Herein, N-doped graphene oxide enfolded reducedtitania (NGO-RT) composite was demonstrated for photocatalytic CO2reduction into CH4. Further, the Pt NPs were deposited on NGO-RTthat increases the catalytic performance towards CH4 formation. Theoptimized Pt1.0%-NGO-RT catalyst displayed a selective visible-lightCO2 reduction into CH4 using a flow reactor system with ≈12 and ≈2 times higheractivity than pristine RT and NGO-RT, respectively. The catalyst demonstratedlong-term stability over 35 h. The improved catalytic performance can beattributed to RT’s downward band bending at the NGO-RT interface, whereelectron transfer from RT to NGO decreases the charge recombination. |
