“…Apart from the already established beneficial effects of adding MOF to polymer matrices, it is also possible to use it to improve the photocatalytic efficiency due to its ability to improve light harvesting, e − /h + separation, and surface redox reaction 195 . Mohaghegh et al 196 synthesized a hybrid nanocomposite consisting of Ag 3 PO 4 /BiPO 4 , graphene, and copper terephthalate MOF and used it to photodecompose a herbicide. This material proved to have good photocatalytic activity under both UV and visible irradiation.…”

Clean water supply has become one of the biggest challenges of the 21st century; therefore, water source protection is of increasing importance. Beyond environmental protection reasons, economic concerns-derived from increasing costs of processing water and wastewater discharge-also prompt industries to use advanced wastewater treatment methods, which ensure higher purification efficiency or even the recycling of water. Therefore, highly effective treatment of oily wastewaters has become an urgent necessity because they are produced in high quantities and have harmful effects on both the environment and human population. However, high purification efficiency can be difficult to achieve, because some compounds are hard to eliminate. Conventional methods are effective for the removal of floating and dispersed oil, but for finely dispersed, emulsified and dissolved oil advanced methods must be used, such as membrane filtration which exhibits several advantages. The application of this technology is restricted by fouling-the major limiting factor-which jeopardizes the membrane performance. In order to reduce fouling, in-depth research is being conducted to make the treatment of oilcontaminated water technically and economically feasible. The present work aims to review the conventional oil separation methods with their limitations and to focus on membrane filtration, which ensures significantly higher purification efficiencies, including the main problem: the flux reduction caused by fouling. This paper also discusses promising solutions, such as membrane modification methods, mostly with hydrophilic and/or photocatalytic nanoparticles and nanocomposites, overviewing the efforts that are being made to develop feasible technologies to treat oil-contaminated waters.

Metal-organic frameworks (MOFs), a new class of crystalline porous materials, can be applied in many fields as adsorbents, supercapacitors, catalysts, and so on because of, among others, their superior properties of large surface area, tunable pore size, diverse structures. However, the low stability and selectivity of traditional MOFs indicate that they are not the best configuration for the applications outlined above. In this case, a type of composite made from an assembly of graphene-based materials and MOFs that exhibits the advantages of the parent materials has attracted widespread attention in recent years. This review provides an overview of the recent developments of MOF/graphene-based materials, focusing on their applications in gas separation/storage, water purification, chemical sensors, batteries, supercapacitors, and catalysts, as well as their preparation methods.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201804950. traditional method, they can be excellent alternatives of single MOFs to overcome the above-mentioned difficulties. [34][35][36][37][38] Graphene-based materials have recently introduced new possible applications because of their unique structure and low toxicity, as well as their excellent electronic, thermal, electrochemical, and mechanical properties. [39] More recently, many reports have confirmed that the introduction of graphene-based materials into other materials can lead to surprising improvements in electronic conductivity and stability. [38,40] Under these circumstances, it is reasonable to consider whether composites made from the assembly of graphene-based materials and MOFs possess extraordinary characteristics given that the parent materials have complementary properties. [40][41][42] Naturally, the idea of hybridizing graphene derivatives with MOFs materialized and soon attracted widespread attention. [43][44][45] According to recent research, composites of MOF/graphene-based materials can integrate the advantages and mitigate the shortcomings of the individual components perfectly, enabling the composites to possess improved stability, enhanced electrical conductivity, high selectivity, and template effects. [34,[46][47][48][49] With the combination of MOF and graphene-based materials, the unexpected interactions take place and bring unique performance in many applications. Thanks to the ionic groups and the aromatic sp 2 domains, graphene-based materials can not only function as structural nodes, but also participate in bonding interactions, which would be more active in MOFs. What's more, carboxylate and pyridine groups of graphene-based materials play important part in the assemble, which could enhance the coordination bonding and guide the growth of MOF, providing a more beneficial structure. These special interactions are unique in MOF/graphenebased materials, which indicates that this kind of materials deserve more attention. As concluded in Scheme 1, the addition of graphene-based material...

“…To expand the photoresponse range of BiPO 4 , constructing composite photocatalysts with Ag 3 PO 4 ( E g = 2.43 eV) can effectively improve the photocatalytic activity of the composite photocatalysts [19,20,21,22,23,24]. However, the Ag 3 PO 4 /BiPO 4 photocatalysts have a high recombination rate of photogenerated electrons (e − ) and holes (h + ) in the degradation of organic pollutions in wastewater [25]. To achieve excellent photocatalytic performances of the photocatalysts, the photoexcited electrons and holes must be efficiently separated [26,27,28,29].…”

A carbon quantum dot (CQDs)/Ag3PO4/BiPO4 heterostructure photocatalyst was constructed by a simple hydrothermal synthesis method. The as-prepared CQDs/Ag3PO4/BiPO4 photocatalyst has been characterized in detail by X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, ultraviolet–visible spectroscopy, and photoelectrochemical measurements. It is demonstrated that the CQDs/Ag3PO4/BiPO4 composite is constructed by assembling Ag3PO4 fine particles and CQDs on the surface of rice-like BiPO4 granules. The CQDs/Ag3PO4/BiPO4 heterostructure photocatalyst exhibits a higher photocatalytic activity for the degradation of the rhodamine B dye than that of Ag3PO4, BiPO4, and Ag3PO4/BiPO4. The synergistic effects of light absorption capacity, band edge position, separation, and utilization efficiency of photogenerated carriers play the key role for the enhanced photodegradation of the rhodamine B dye.
