Photocatalytic Performance of the MOF-Coating Layer on SPR-Excited Ag Nanowires

Abstract

The photoactive metal−organic frameworks (MOFs) were controllably coated on the surface plasmon resonanceexcited Ag nanowires in a layer manner to adjust the photocatalytic activity. The influence of the thickness of the MOF coating layer on the photocatalytic activity was investigated. A thicker MOF coating layer not only facilitated the photogenerated electron−hole separation efficiency but also provided a larger Brunauer−Emmett−Teller surface area, thus enhancing the photocatalytic activity. This work provided a new way to adjust the photocatalytic activity of the photoactive MOF.

Space and Time Crystal Engineering in Developing Futuristic Chemical Technology

“…Metal sulphide nanoparticles, precisely MoS2, CdS are used for decorating MOF in photocatalytic hydrogen evolution reactions [27]. Metal nanoparticles such as silver nanoparticles [28], Pt nanoparticles, combined nanoparticles [29] or silver iodide [30] are often used for decorating MOFs. Now, if we want to design a multipurpose catalyst, we can consider decorating the nanoparticles on MOFs with specific but different photocatalytic activities.…”

Gel-like Ag-Dicyandiamide Metal–Organic Supramolecular Network-Derived g-C3N4 for Photocatalytic Hydrogen Generation

“…28 However, metal-incorporated freeze-dried MOSN-derived g-C 3 N 4 using dicyandiamide as a precursor for photocatalytic H 2 production has never been reported. In this study, Ag and dicyandiamide were used to prepare a metal−organic supramolecule because Ag metal exhibits a surface plasmon resonance (SPR) effect that effectively induces electron transfer at the metal−semiconductor interface; 29,30 the cyano group of dicyandiamide can be easily conjugated with Ag + according to the following equation 31…”

In addition, the −NH 2 groups of dicyandiamide can self-condense to polymerize upon heating to produce heptazine units, a fundamental block of the g-C 3 N 4 structure.…”

Signal On–Off Electrochemical Sensor for Glutathione Based on a AuCu-Decorated Zr-Containing Metal–Organic Framework via Solid-State Electrochemistry of Cuprous Chloride

“…Therefore, to reduce metal accumulation and improve sensitivity, a nanomaterial with a large surface area and large number of active sites is highly required as the carrier or supporter for the immobilization of AuCu bimetals. The metal−organic framework (MOF) is a good candidate for its unique properties such as uniform structure, high specific surface area, and morphological maneuverability, 32−34 providing the possibility to immobilize Ag NPs, 35 Co 3 O 4 NPs, 36 and Au NPs. 37 In the present work, a Zr-containing metal−organic framework (Zr-MOF) with a regular shape and large surface area was synthesized by a simple hydrothermal method and utilized as the support for the in situ growth of AuCu bimetals to obtain a novel Zr-MOF@AuCu nanocomposite (Scheme 1A).…”
