The synergy between electronic anchoring effect and internal electric field in CdS quantum dots decorated dandelion-like Fe-CeO2 nanoflowers for improved photocatalytic hydrogen evolution

CdS/ZnS/ZnO ternary heterostructure nanofibers fabricated by electrospinning for excellent photocatalytic hydrogen evolution without co-catalyst

“…Binary semiconductor HSs with three different configurations: type-I [35], type-II [36,37], and Z-scheme [38] have been reported. In recent years, ternary HSs consisting of three semiconductors have attracted considerable attention.…”

UV-Vis Activated Cu2O/SnO2/WO3 Heterostructure for Photocatalytic Removal of Pesticides

“…The synthesis procedure allows WO 3 and SnO 2 to act as nucleation sites for the following component, which facilitates the formation of crystalline structure. There was no indication of mixed metal oxide formation, but the presence of amorphous compounds cannot be excluded [ 36 , 37 ]. Due to the synthesis procedure, no preferential orientation was observed.…”

Flower-like Ag2WO4/CeO2 heterojunctions with oxygen vacancies and expedited charge carrier separation boost the photocatalytic degradation of dyes and drugs

“…4 However, CeO 2 with a band gap of 3.0 eV only responds to near ultraviolet light, and it is difficult to separate the photogenerated carriers, which limits the efficient conversion of solar energy. 5 A variety of strategies (e.g., defect modification, 6 regulating morphology, 7,8 and constructing heterojunctions [9][10][11] have been adopted to improve the visible light catalytic efficiency of CeO 2 . However, a single optimization strategy is usually adopted, limiting performance improvement.…”

“…Taking advantage of the merits of morphology design and component manipulation, Ma et al synthesized the dandelion-like Fe-CeO 2 /CdS (FeCe/Cd) HS heterojunction with a capability of facilitating the separation of charge carriers. 11 However, it remains a challenge to discover a suitable semiconductor photocatalyst that can function as a partner to combine the nanostructured CeO 2 with surface defects to create an efficient heterojunction photocatalyst.…”

“…5 A variety of strategies ( e.g. , defect modification, 6 regulating morphology, 7,8 and constructing heterojunctions 9–11 ) have been adopted to improve the visible light catalytic efficiency of CeO 2 . However, a single optimization strategy is usually adopted, limiting performance improvement.…”
