A copper(ii)-based MOF film for highly efficient visible-light-driven hydrogen production

Abstract

A copper(ii)-based MOF film (MOF-199/Ni) prepared by electrodeposition shows exceptionally high photocatalytic hydrogen production rates with and without Pt as the co-catalyst.

Zn‐Vacancy Engineered S‐Scheme ZnCdS/ZnS Photocatalyst for Highly Efficient Photocatalytic H2 Evolution

“…It's beneficial for improving photocatalytic activity to reduce the particle size of MOF by shortening the optical and diffusion path. [35] The TEM images further reveal the morphological and structural changes of the fresh and used ZnCdS/MOF-5 photocatalyst. The ZnCdS particles are strongly coupled to the surface of MOF-5 nanosheets (Figure 3a).…”

“…[34] For example, a copper (II)based MOF film is acquired by electrodeposition reveals glorious photocatalytic H 2 production performance and the film can be reused without substantial loss at the process of photocatalytic reaction. [35] Besides, MOF-derived heterojunction as the nanocatalysts tremendously improved the surface H 2 production kinetics can transform solar energy into hydrogen energy effectively. [36] All the researches indicate that the important role of MOFs in the field of photocatalysis.…”

Monometallic and bimetallic Cu–Ag MOF/MCM-41 composites: structural characterization and catalytic activity

“…Nanoporous metal-organic frameworks (MOFs) have received more attention due to their attractive properties such as high surface area, high porosity, low density and crystalline character as well as their composition and chemical structure. [1][2][3] Therefore, MOFs used in various applications involving chemical separation, 4 gas adsorption and storage, 5 drug delivery, 6 luminescence, 7 biomedical imaging 8 and used in many reactions as a catalyst. 9 There is a strong host-guest interaction in the MOF between the metal nanoparticles and the framework via coordination and p-p forces which depend on its electronic properties and structure that in turn enhance the catalytic activity and stability.…”

Effect of Benzene Derivatives as Guest Molecules on Semiconductor Properties of MOF‐199

“…Pure MOF-199 is reported to have a flat band potential of À 0.27 eV vs. SCE. [36] Flat band potential of a compound indicates the density of surface charge on the semiconductor and its band bending when in contact with an electrolyte. High carrier density of a semiconductor leads to a higher band bending which results in a wider space charge region.…”
