将Ag和Co双助催化剂负载在Al掺杂的SrTiO 3(AgCo/Al-SrTiO 3)上,在波长大于300 nm的光照射下,以H2O为电子给体,CO生成速率显著提高,对CO的选择性高达99.8%。此外,在AgCo/Al-SrTiO 3上的CO生成速率(52.7 μmol h−1)比在Ag/Al-SrTiO 3上的CO生成速率(4.7 μmol h−1)高十几倍。当在365 nm波长下光照射时,AgCo/Al-SrTiO 3上CO析出的表观量子效率约为0.03%,CO析出选择性为98.6%(7.4 μmol h−1)。Ag和Co助催化剂被发现作为还原和氧化网站,促进CO和O2的生成,分别在Al-SrTiO 3表面上。在Al-SrTiO_3上沉积Ag和Co双助催化剂可显著提高其光还原CO_2的活性,并具有极高的CO生成选择性(99.8%),其中Ag和Co分别使CO_2还原和H_2 O氧化成为可能。
Loading Ag and Co dual cocatalysts on Al-doped SrTiO3 (AgCo/Al-SrTiO3) led to a significantly improved CO-formation rate and extremely high selectivity toward CO evolution (99.8%) using H2O as an electron donor when irradiated with light at wavelengths above 300 nm. Furthermore, the CO-formation rate over AgCo/Al-SrTiO3 (52.7 μmol h−1) was a dozen times higher than that over Ag/Al-SrTiO3 (4.7 μmol h−1). The apparent quantum efficiency for CO evolution over AgCo/Al-SrTiO3 was about 0.03% when photoirradiated at a wavelength at 365 nm, with a CO-evolution selectivity of 98.6% (7.4 μmol h−1). The Ag and Co cocatalysts were found to function as reduction and oxidation sites for promoting the generation of CO and O2, respectively, on the Al-SrTiO3 surface. Deposition Ag and Co dual cocatalysts onto Al-SrTiO3 significantly improves its activity for photoreduction of CO2 by H2O, with extremely high selectivity to CO evolution (99.8%), in which Ag and Co enable CO2 reduction and H2O oxidation, respectively.
