Highly active and stable TiO2-supported Au nanoparticles for CO2 reductionHighly active and stable TiO2-supported Au nanoparticles for CO2 reduction Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2018-07-032017enAu nanoparticles (2.2 nm) deposited on TiO2 by the deposition-precipitation method were found to be extremely active and stable for CO2 hydrogenation to CO. A CO2 to CO yield up to 50% was achieved at temperatures as low as 400 °C for at least 60 h. Under identical reaction conditions, both bare TiO2 and Au/Al2O3 were practically inactive for CO2 reduction. The unique combination of the Au nanoparticles and TiO2 support – linked to a peculiar synergistic effect – is essential to the enhanced CO2 reduction activity.http://creativecommons.org/licenses/by/4.0/Catalysis Communications9852-56 Kyriakou Vasileios Vourros A.
