Nowadays, photoelectrocatalytic (PEC) reduction of CO 2 represents a very promising solution for storing solar energy in value-added chemicals, but so far it has been hampered by the lack of highly efficient catalyst of photocathode. Enlightened by the Calvin cycle of plants, here we show that a series of three-dimensional C/N-doped heterojunctions of Zn x :Co y @Cu are successfully fabricated and applied as photocathodes in the PEC reduction of CO 2 to generate paraffin product. These materials integrate semiconductors of p-type Co 3 O 4 and n-type ZnO on Cu foam to construct fine heterojunctions with multiple active sites, which result in excellent CC coupling control in reduction of CO 2. The best catalyst of Zn 0.2 :Co 1 @Cu yields paraffin at a rate of 325 mg$h À1 under À0.4 V versus saturated calomel electrode without H 2 release. The apparent quantum efficiency of PEC cell is up to 1.95%.

A novel crossed-layer-structure MoS2/g-C3N4 (graphitic carbon nitride) was synthesized by a facile method, and was characterized by a collection of analytical techniques: X-ray diffraction patterns, FT-IR spectra, SEM, TEM, and XPS.

A novel strategy was applied for the preparation of MoS2/graphitic carbon nitride (g-C3N4) with porous morphology.

The photoelectrochemical (PEC) reduction of CO2 into organic chemicals on the semiconductor is considered as a feasible plan to address global energy crisis and climate warming. Herein, the heterojunctions NiMoO4/ZnO-x...
