Photocatalysis has been considered as a promising green technology to solve the energy and environmental problems through the photocatalytic water splitting into hydrogen production and photoreduction of CO2 into high value-added hydrocarbons. The current change is to develop highly efficient photocatalys. Nanostructured materials for photocatalysis have attracted considerable attention due to their unique physical and chemical properties compared with their corresponding bulk materials. Among various architectures, two-dimensional (2D) nanosheets with thickness generally below 100 nm are of great promise for highly efficient photocatalysis. Herein, some very recent research progress in my group has been summarized on the rational design and controlled synthesis of 2D 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; 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.
