Опубликована: Фев. 5, 2025

MOF-based heterojunctions can significantly enhance the efficiency of photocatalytic hydrogen production; however, construction efficient remains a formidable challenge. In this study, we successfully developed series Type II by growing TiO2 on Cr-based MOF, thereby regulating generation, separation, and transportation photogenerated charge carriers to improve evolution performance. Among these, 23%TiO2/MIL-101(Cr) photocatalyst exhibited highest production activity, achieving 884.01 μmol g–1 in just 5 h, which is 6.8 6.0 times that pure MIL-101(Cr) TiO2, respectively. Additionally, demonstrated excellent cyclic stability. Tiny particles were proven mainly deposited surface N2 sorption isotherm analyses, transmission electron microscopy (TEM), high-resolution TEM, high-angle annular dark field scanning microscopy, etc. Characterization techniques such as situ XPS confirmed formation TiO2/MIL-101(Cr) heterostructure. Band structure analysis indicates meets thermodynamic requirements for production. Furthermore, transient photocurrent measurements, electrochemical impedance analysis, photoluminescence reveal possesses superior capabilities carrier transport, resulting from kinetic perspective. This research offers valuable insights into preparation development photocatalysts

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Фев. 4, 2025

The photocatalytic hydrolysis method represents a significant potential solution to the dual challenges of energy security and environmental sustainability. selection suitable materials systems is paramount importance for successful implementation hydrogen production technology. In this study, in situ reduction Co nanoparticles on MnO was successfully performed by calcining MnCo-PBA. Furthermore, graphdiyne (GDY) introduced physical agitation. introduction GDY reduced Co/MnO agglomeration made Co/MnO/GDY catalyst exhibit high activity production, with an optimum rate 2117.33 μmol·g-1·h-1, which 4.88 2.67 times higher than that Co/MnO, respectively. results photoelectrochemical test indicate composite has better photogenerated carrier separation efficiency. X-ray photoelectron spectroscopy, density functional theory calculations, electron paramagnetic resonance were used investigate transfer mechanism during process, confirming presence S-scheme heterojunction ohmic junction, enhance carriers. GDY-based constructed study significantly bimetallic catalysts.
