Nanostructured Photocatalysts for Efficient Solar Fuels
Technical Institute of Physics and Chemistry, Chinese Academy of Sciences,
Abstract: Nanostructured materials for photocatalysis have attracted considerable attention due to their unique physical and chemical properties compared with their corresponding bulk materials. Herein, some very recent research progress in my group has been summarized on the rational design and controlled synthesis of nanostructured photocatalysts for highly efficient visible light-driven H2 evolution and photocatalytic conversion of CO2 or CO into high value-added hydrocarbons by enhancing the light absorbance and separation of electron-hole pairs of photocatalysts. I) By developing high conductive Cd nanosheet support for CdS, the quantum efficiency of photocatalytic H2 production of CdS/Cd achieved 33% at 420 nm; II) By creating more oxygen defects in ultrathin ZnAl-LDH nanosheets, the photocatalytic reduction of CO2 with water over ZnAl-LDH exhibited stable activity of ≈7.6 μmol g-1 h-1; in ultrathin ZnAl-LDH nanosheets N2 can be efficiently reduced into NH3 under visible-light irradiation; III) By constructing heterogeneous interface structure, NiO/Ni nanocatalysts exhibited an unexpectedly high selectivity of 60% for C2-C7 hydrocarbons in the CO hydrogenation reaction under visible-light irradiation.[1-7]
