Two-dimensional heterostructures for photocatalytic CO2 reduction

Fabrication and characterization of Z-scheme BiOCl/C/Cu2O heterojunction nanocomposites as efficient catalysts for the photocatalytic reduction of CO2

“…19,20 Therefore, the combination of BiOCl and Cu 2 O is conducive to improving carrier separation and transfer, further perfecting the photocatalytic activity and stability under sunlight irradiation. 21 Although Cu 2 O/BiOCl heterojunction is reported to possess better photocatalytic activity than that of a single component, it is far from the expected purpose. 22 The easy aggregation characteristics of semiconductors critically confine the separation of electron-hole pairs.…”

Recent advances in MXenes: a promising 2D material for photocatalysis

“…[8][9][10] The four primary functions of photocatalysis are photocatalytic H 2 production, CO 2 reduction, nitrogen fixation, and degradation. [11][12][13][14][15] Photocatalytic solar energy conversion can be divided into three processes: light absorption, charge separation and transfer, and surface reaction. These three steps separately contribute to improving the total conversion efficiency.…”

WS2 supported PtOx clusters for efficient photocatalytic CO2 reduction: a DFT study

“…1,2 Thus, there is an urgent demand to develop green technologies for solar-to-chemical conversion that could simultaneously solve the environmental problems and global energy crunch. [3][4][5][6] Photocatalytic reduction of CO 2 with lower energy input has been seen as an ecofriendly method to alleviate the aforementioned crisis. [7][8][9] Because of the chemical inertness of the CQO double bond, highly efficient photocatalysts with excellent photocatalytic performance and superior product selectivity are still far from being achieved.…”
