“…On the other hand, the characteristic peaks of DMPO-•OH was very weak. In conclusion, the •O 2 − radical plays an important role while few •OH radicals were involved in the photocatalytic system, which is consistent with the previous scavenger result [39,40] .…”

“…Since the Frank discovered that photocatalytic reaction can oxide CN − to OCN − , photocatalytic technology in the environmental‐protection application has received wide attention of researchers at home and abroad . Profiting from the unique advantages of ultrathin 2D semiconductors, such as a large space for light absorption and photocatalytic reaction and the ultrathin thickness facilitates the rapid transfer of photogenerated carriers to the surface or interface, the 2D semiconductors show great prospect for photodegradation organics . For example, Wang and co‐workers successfully synthesized freestanding monolayer Bi 2 WO 6 with a sandwich substructure of [BiO] + ‐[WO 4 ] 2 ‐[BiO] + by cetyltrimethylammonium bromide (CTAB) assistance (Figure ).…”

The search for highly active photocatalysts remains one of the most challenging tasks for realizing efficient solar energy utilization. Inspired by their unique and excellent physicochemical properties, ultrathin two-dimensional (2D) semiconductors present great advantages in photocatalytic researches. In this review, we summarize the state-of-art progress on the ultrathin 2D semiconductors with a particular emphasis on their recent advances in energy and environment applications. First, we introduce the historical developments of 2D nanomaterials, and outline their advantages in terms of photocatalysis. Second, the classifications of ultrathin 2D semiconductors are summarized based on their structure and compositions. Further, various energy and environment applications including water splitting, CO 2 reduction, N 2 fixation, organic syntheses, NO x removal, water treatment, and sterilization in recent years (mainly in the recent 3 years) are highlighted in detail. Finally, the personal perspectives on future challenges and outlooks in the field of energy and environment applications are featured.[a] Dr.

“…An example of a partially suitable design of type II heterostructure has been shown for two-dimensional nanosheets SbN2O6/g-C3N4 by Zhang et al [41]. The g-C3N4 conduction band electrons directly inject to the more positive SbN2O6 conduction band facilitating the production of a superoxide radical, while the holes slant to migrate to g-C3N4 valence band.…”

Although, plenty of photocatalytic approaches have been developed in the past few decades to overcome major drawbacks, such as; wide band gap and fast volume/surface recombination of the charge carriers, the researchers still need to carry out careful systematic studies before conducting experiments based on physicochemical properties of a system. Thus, in this review, a detailed discussion of the band edge positions controlling the migration and charge separation of the produced charged carriers and its impact onto the photocatalytic systems are provided. The knowledge of band edge positions is a crucial prerequisite to a rational design of an efficient photocatalytic system. The enhancement mechanism should match these criteria to be reliable in the field of heterogeneous photocatalysis science.
