Inadequate photo-generated charge separation, migration, and utilization efficiency limit the photocatalytic efficiency. Herein, a MoS2 /MIL-53(Fe) photocatalyst/activator with S-scheme heterojunction structure is designed migration behavior modulated by internal electric field (IEF). The IEF intensity enhanced to 40 mV modulating band bending potential depletion layer length of . electron process boosted constructing bridge (Fe-O-S) as driving force, confirmed density functional theory calculation. Compared pristine materials, photocurrent significantly 27.5 times. Contributed visible-light-driven cooperative catalytic degradation high-efficiency direct reduction dichlorination process, satisfactory chlorinated antibiotics removal detoxification performances are achieved. This study opens up new insights into application heterojunctions in activation PDS environmental remediation.

Research in heterogeneous photocatalysis is burgeoning and rapidly evolving given the benefits of performing demanding chemical transformations under mild conditions. Remarkable success has been achieved photodegradation as an advanced oxidation option water or air decontamination. Artificial photosynthesis, whereby photonic (sunlight) energy can be stored form (solar) fuels, represents encouraging strategic goal. Specially latter case, design effective light-absorbing semiconductors with properly aligned band potentials co-catalysts enabling intricate multi-electron redox reactions key. As described this review, metal phosphates offer distinct possibilities to become tuneable regards traditional oxides, owing effects introducing phosphorus electronic lattice structures. This most clearly exemplified case Ag3PO4, slightly widening bandgap parent oxide while maintaining appropriate valence energies, which conjunction result highly active activity visible light. Other non-noble late (e.g. Co, Cu, Fe, Ni) early Ti, Zr, V, Nb) transition tend have superior reducing properties, engineering might efficient for fuel production, chiefly H2 evolution CO2 reduction. Their more complex structural features require dedicated synthetic efforts, regrettably overlooked hitherto, effectively explore their real possibilities. BiPO4 a UV-active semiconductor ample applicability photocatalysis, including hydrogen production; other approaches enable its response light are discussed. Natural hydroxyapatites proven resourceful families light-responsive components via by foreign doping. Beyond semiconductors, discovery development surface (mostly cobalt) O2 key advancement solar splitting. review scrutinises thoroughly analyses research on use heterojunction nanocomposites photoelectrochemical systems catalysts.

The photocatalytic activity of individual metal–organic frameworks (MOFs) such as UiO-66-NH2 and MIL-101(Fe) is less satisfactory due to the disappointing separation rate electron–hole pairs weak solar energy utilization efficiency. In this context, we develop hierarchical dual Z-scheme heterostructured photocatalysts prepared via an in situ hydrothermal synthesis method anchoring cadmium sulfide (CdS) nanoparticles onto (UiO-66-NH2)-(MIL-101(Fe)) (UM) frameworks. Attributed synergistic effects CdS, UiO-66-NH2, MIL-101(Fe), (UiO-66-NH2)-(MIL-101)(Fe)-CdS (UM-CdS) exhibits outstanding degradation activities toward TC degradability. Typically, 10 mg UM-CdS achieved 87% within 140 min, which 8.7, 2.4, 1.4 times than those higher with a dosage catalysts compared previous reports. primarily attributed its structure, provides numerous active sites. Additionally, special heterostructure not only migration mechanism for charge carriers, facilitates efficient photoinduced electrons holes, but also promotes redox capability UM-CdS. Furthermore, trapping tests demonstrated that •O2–, •OH, h+ were main species during process. products or intermediates studied in-depth through liquid chromatography–mass spectrometry (LC-MS) technique. Besides, possesses excellent stability, retaining more 90% initial after fifth cycle.
