“…Under negative bias, electron/hole pair recombination is minimized by more efficient charge separation, favoring photoelectrocatalysis target [34,43]. The CO 2 reduction occurs at the Pt surface, where it is converted to •CO 2 - [6,[44][45][46] and hence protonation and deprotonation reactions occur to form the products [12,47]. The overall charge transfer mechanism characterizes the p-n junction [48].…”

“…The mechanism is proposed in agreement with the literature [21,42,50,51], and is based on e -and H • transfer. Latest is generated by water oxidation by the holes at the counter electrode [12,17]. The possible reaction shows two different 12 pathways; one of them driving to ethanol formation, and the other to acetone.…”

“…Among the various possible approaches, photocatalysis [2][3][4][5][6] and photoelectrocatalysis [7][8][9][10] have been demonstrated as promising, mainly because these techniques have advantages over CO 2 reduction that can be tuned by using different materials as a photocatalyst when combined with light irradiation. This simple arrangement is able to provide electrons and reactive intermediates able to produce several kinds of hydrocarbons, for instance [11,12]. The photoelectrocatalytic method is based on the use of a semiconductor irradiated by light, whose energy is greater than or equal tothat of the band gap, and simultaneously biased by a gradient potential.…”

“…Copper and copper oxides [11][12][13][14][15][16][17][18][19] are the most known widely known p-type semiconductor used for CO 2 reduction, but these suffer from a lack of stability. From this some groups have presented the combination of metals and oxides for robust materials.…”

The energy crisis and global warming become severe issues. Solar-driven CO 2 reduction provides a promising route to confront the predicaments, which has received much attention. The photoelectrochemical (PEC) process, which can integrate the merits of both photocatalysis and electrocatalysis, boosts splendid talent for CO 2 reduction with high efficiency and excellent selectivity. Recent several decades have witnessed the overwhelming development of PEC CO 2 reduction. In this review, we attempt to systematically summarize the recent advanced design for PEC CO 2 reduction. On account of basic principles and evaluation parameters, we firstly highlight the subtle construction for photocathodes to enhance the efficiency and selectivity of CO 2 reduction, which includes the strategies for improving light utilization, supplying catalytic active sites and steering reaction pathway. Furthermore, diversiform novel PEC setups are also outlined. These exploited setups endow a bright window to surmount the intrinsic disadvantages of photocathode, showing promising potentials for future applications. Finally, we underline the challenges and key factors for the further development of PEC CO 2 reduction that would enable more efficient designs for setups and deepen systematic understanding for mechanisms.
