“…This was due to the surface enhancement effect of the Raman signals caused by the Ag cluster SPR effect, indicating that a strong interaction was formed between Ag clusters and OV-LTO. 40 Therefore, it could be inferred that Ag/AgCl and OV-LTO in AAOL were not simply physically mixed but there was a strong interaction. From previous studies, it can be inferred that this strong interaction force may be attributed to the formation of a Schottky barrier, which facilitates a strong electrostatic attraction between Ag/AgCl and OV-La 2 Ti 2 O 7 .…”

“…When the reaction time prolonged to 6 h, clear peaks at 273.6, 325, 716.6 and 806.0 cm −1 , which are labelled by blue squares, identify the monoclinic phase of WO 3. [43,44] In details, the peaks located at 273.6 and 325 cm −1 are attributed to the O−W−O bending modes while the stretching vibrations of O−W−O are reflected by two peaks at 716.6 and 806.0 cm −1. [45] Further increasing the reaction time, the peaks of the WO 3 peaks gets gradually intense, which is in consist with the XRD results.…”

With attractive visible‐light response and chemical stability, CuWO4 has emerged to be a promising candidate as a photoanode for photoelectrochemical (PEC) water oxidation. In this work, we report a one‐step hydrothermal method to prepare CuWO4‐based films directly grown on a conductive glass substrate from a stable precursor solution. By controlling the reaction duration, CuWO4/WO3 heterojunctions with urchin‐like nanoarray morphology are obtained. The CuWO4/WO3 film obtained with an optimized hydrothermal reaction time exhibits an onset potential of 0.6 V and a photocurrent density of 0.48 mA cm−2 at 1.23 V vs. RHE, which is almost five times that of bare CuWO4. The superior structure of the urchin‐like array with large surface area, optimizing film thickness for adequate light absorption and formation of heterojunctions for efficient charge separation conjointly, contributes to the improved performance as well as robust stability.

“…Upon irradiation, electrons in silver halides are excited and accepted by Ag + to produce metallic Ag atoms. Ag/AgX has been frequently studied as a cocatalyst to improve the performance of other semiconductors such as TiO 2 , − ZnO, , g-C 3 N 4 , , WO 3 , , BiVO 4 , , Bi 2 MoO 6 , , and MOFs. , MOFs are also often combined with supporting materials such as graphitic carbon nitride (g-C 3 N 4 ) and graphene-based materials, which possess abundant π–π conjugations and serve as electron shuttles to separate excited e – /h + . ,, …”

Metal Organic Frameworks (MOFs) as Photocatalysts for the Degradation of Agricultural Pollutants in Water

Increasing demand for food due to rapid population growth has exerted unprecedented pressure on the global agricultural industry. Agrochemicals are widely used to ensure productivity, leading to the prevalence of legacy and emerging agricultural chemicals in the environment, most of which are toxic and persistent. Metal−organic frameworks (MOFs) as a group of novel photocatalytic materials with ultrahigh porosity and tunability have demonstrated high potential for efficient removal of these recalcitrant pollutants. This critical review aims to present the potential of MOF-catalyzed photodegradation of pesticides and antibiotics. Initially, the capabilities of different MOF-based composites to harvest visible light are compared. Examples include MOFs combined with bismuth oxyhalides (BiOX) and graphite oxide (GO). Mechanisms involved in MOF-induced photocatalytic processes such as electron−hole (e − /h + ) separation, generation of reactive species, and degradation pathways of representative pollutants as well as impacts of water chemistry are illustrated in detailed. Research on applying MOF-catalyzed processes is largely in progress, and many more studies with greater mechanistic evaluation are needed to fully assess the potential of such processes to depollute water.
