High-efficient separation of photoinduced carriers on double Z-scheme heterojunction for superior photocatalytic CO2 reduction

Z‐Scheme Photocatalytic Systems for Carbon Dioxide Reduction: Where Are We Now?

“…In particular,Z -scheme CO 2 reduction has become one of the hottest topics and been exhaustively explored ( Figure 4) in recent years. [51,52] To the best of our knowledge,t here is no recent review that provides acomprehensive discussion of Zscheme (from indirect to direct) photocatalytic systems focusing on CO 2 reduction. Therefore,w ew ec onsidered it beneficial to present insights into the latest progress made in the realm of Z-scheme photocatalytic systems for CO 2 reduction.…”

“…Due to those aforementioned virtues, the artificial Z‐scheme photocatalytic systems have been extensively explored in pollutant degradation, [42–44] water splitting, [45–47] nitrogen fixation, [48, 49] organic synthesis [50] and so forth. In particular, Z‐scheme CO 2 reduction has become one of the hottest topics and been exhaustively explored (Figure 4) in recent years [51, 52] . To the best of our knowledge, there is no recent review that provides a comprehensive discussion of Z‐scheme (from indirect to direct) photocatalytic systems focusing on CO 2 reduction.…”

Exciton Dissociation on Double Z‐scheme Heterojunction for Photocatalytic Application

“…[11] To address this shortcoming, introduction of a third component in the heterostructure to increase the CB potential can be an effective strategy. In this context, numerous ternary systems such as ZnO/ZnWO 4 /CN, [12] NiL/NiO x /CN, [13] Ag-rGO/CN, [14] CN/MoS 2 /Ag 3 PO 4 , [15] etc. have been constructed and their optimization displayed high light-harvesting, utilization, and improved charge separation efficiency with enhanced photocatalytic performance.…”

Z‐Schema‐Photokatalysesysteme für die Kohlendioxidreduktion: Wo stehen wir heute?

“…Insbesondere die Z-Schema-CO 2 -Reduktion entwickelte sich zu einem heißen Thema, dem man sich in den letzten Jahren intensiv gewidmet hat (Abbildung 4). [51,52] Unseres Wissens gibt es derzeit keine aktuelle Übersicht, die eine umfassende Diskussion von (indirekten bis direkten) Z-Schema-Photokatalysesystemen mit dem Schwerpunkt der Fortschritte in der CO 2 -Reduktion bietet. Deshalb scheint es sehr passend, hier den Stand der aktuellen Fortschritte auf dem Gebiet der Z-Schema-Photokatalysesysteme fürd ie CO 2 -Reduktion zu präsentieren.…”
