Heteroepitaxial MOF-on-MOF Photocatalyst for Solar-Driven Water Splitting

ACS Nano, Journal Year: 2024, Volume and Issue: 18(31), P. 20201 - 20212

Published: July 30, 2024

Assembly of different metal-organic frameworks (MOFs) into hybrid MOF-on-MOF heterostructures has been established as a promising approach to develop synergistic performances for variety applications. Here, we explore the performance heterostructure by epitaxial growth MIL-88B(Fe) onto UiO-66(Zr)-NH2 nanoparticles. The face-selective design and appropriate energy band structure alignment selected MOF constituents have permitted its application an active heterogeneous photocatalyst solar-driven water splitting. composite achieves apparent quantum yields photocatalytic overall splitting at 400 450 nm about 0.9%, values that compare much favorably with previous analogous reports. Understanding this high activity gained spectroscopic electrochemical characterization together scanning transmission electron microscopy (STEM, TEM) measurements. This study exemplifies possibility developing operates under Z-scheme mechanism exhibits outstanding toward solar light.

Delineating the Role of Vacancy Defects in Increasing Photocatalytic Hydrogen Production in an Amorphous Metal–Organic Framework Coordinated Graphitic Carbon Nitride

ACS Applied Energy Materials, Journal Year: 2023, Volume and Issue: 6(18), P. 9207 - 9217

Published: May 30, 2023

The instability in aqueous solutions has impeded the effective employment of metal–organic frameworks (MOFs) for various photocatalytic applications. Recent literatures have proven that certain supports like graphitic carbon nitride (g-C3N4) can improve water stability and meet other functionalities responsible splitting. To expound on mechanistic details central to photoactivity g-C3N4/MOF systems, we relate activity an amorphous nickel imidazole framework (aNi-MOF) with different vacancy (carbon nitrogen) defects engineered g-C3N4 systems. Vacancy significantly alter electronic structure characteristics photoexcited charge carriers thus semiconductor photocatalysts. In this framework, by elucidation both experimental theoretical studies, carbon-defective aNi-MOF (CvCN/aNi) proves be a potential candidate speed up hydrogen evolution reaction. results also potentially accord reactive interaction between Ni–N bond is vital CvCN/aNi photocatalyst producing 3922.01 μmol g–1 3 h, which 3900 1700 times better than those pristine g-C3N4, respectively. Our report provides insight into correlating mechanism system role reactions.
