“…The ZnS passivation layer has been most commonly applied, [85][86][87][88][89][90][91][92][93]126] which can be coated by a straightfor-ward method and is significantly effective to enhance the PEC performances of the QD-sensitized photoelectrodes. Furthermore, other wide-bandgap semiconductors including Al 2 O 3 , [127][128][129][130] ZnFe 2 O 4 , [131] and ZnSe [132] have been studied for application as the passivation layer.…”

Solar‐driven photoelectrochemical (PEC) hydrogen production is one potential pathway to establish a carbon‐neutral society. Nowadays, quantum dots (QDs)‐sensitized semiconductors have emerged as promising materials for PEC hydrogen production due to their tunable bandgap by size or morphology control, displaying excellent optical and electrical properties. Nevertheless, they still suffer from anodic corrosion during long‐term cycling, offering poor stability. This Review discussed advancements to improve long‐term stability of QDs particularly in terms of cocatalysts and passivation layers. The working principle of PEC cells was reviewed, along with all important configurations adopted over recent years. The equations to assess PEC performance were also described. A greater emphasized was placed on QDs and incorporation of cocatalysts or passivation layers that could enhance the PEC performance by influencing the charge transfer and surface recombination processes.

Developing efficient and affordable catalysts is of great significance for energy and environmental sustainability. Heterostructure photocatalysts exhibit a better performance than either of the parent phases as it changes the band bending at the interfaces and provides a driving force for carrier separation, thus mitigating the effects of carrier recombination and back‐reaction. Herein, the photo/electrochemical applications of a variety of metal sulfides (MSx) (MoS2, CdS, CuS, PbS, SnS2, ZnS, Ag2S, Bi2S3, and In2S3)/TiO2 heterojunctions are summarized, including organic degradation, water splitting, and CO2 reduction conversion. First, a general introduction on each MSx material (especially bandgap structures) will be given. Then the photo/electrochemical applications based on MSx/TiO2 heterostructures are reviewed from the perspective of light harvesting ability, charge carrier separation and transportation, and surface chemical reactions. Special focus is given to CdS/TiO2 and PbS/TiO2‐based quantum dot sensitized solar cells. Ternary composites by taking advantages of positive synergetic effects are also well summarized. Finally, conclusions are made regarding approaches for structure design, and the authors' perspective on future architectural design and electrode construction is given. This work will make up the gap for TiO2 nanocomposites and shed light on the fabrication of more efficient MSx‐metal oxide junctions in photo/electrochemical applications.
