Highly Efficient Photothermocatalytic CO2 Reduction in Ni/Mg-Doped Al2O3 with High Fuel Production Rate,Large Light-to-Fuel Efficiency,and Good Durability
文献摘要：
A novel nanocomposite of Ni nanoparticles loaded on Mg-doped Al2O3(Ni/Mg-Al2O3)was prepared.By photothermocatalytic CO2 reduction with methane(CRM)merely using focused UV-vis-IR illumination on Ni/Mg-Al2O3,high production rates of H2(rH2,69.71 mmol min-1 g-1)and CO(rCO,74.57 mmol min-1 g-1)and an extremely large light-to-fuel efficiency(η,32.9％)are acquired.High rH2and rCO(51.07 and 59.66 mmol min-1 g-1)and a large n(32.5％)are acquired even by using focused λ＞560 nm vis-IR illumination.Ni/Mg-Al2O3 shows good durability for photothermocatalytic CRM due to the side reaction of carbon deposition being enormously inhibited in comparison with a reference catalyst of Ni nanoparticles loaded on Al2O3.The enormous carbon deposition inhibition is ascribed to the presence of a fence of CO2 molecules(strongly adsorbed on Mg-doped Al2O3)around Ni nanoparticles,which block the polymerization and growth of carbon species to nanofibers by promoting the oxidation of carbon species formed by CH4 dissociation.The high photothermocatalytic activity of Ni/Mg-Al2O3 arises from efficient light-driven thermocatalytic CRM.A photoactivation is found to considerably raise the photothermocatalytic activity of Ni/Mg-Al2O3 because of the apparent activation energy(Ea)being substantially decreased upon focused illumination.The Ea reduction is associated with the rate-determining steps of CRM(e.g.,CH4 dissociation and the oxidation of carbon species)being accelerated upon focused illumination.
