“…It could be used to effectively load drugs and is beneficial to package various compounds and therapeutic drugs [6,7]. The complexes formed with Cu 2+ have thousands of applications; for example as nucleic acid cleavage enzymes because of their cleavage activity to DNA, and some complexes have certain anticancer activities [8,9]. As a new type of ligand, 6-oxo-2-phenyl-1,6-dihydropyrimidine-4-carboxylate coordinate with Cu 2+ to form the title complex.…”

“…Another valid approach to reduce charge recombination rate and improve MOFs photocatalytic performance is based on their coupling with semiconductor nanoparticles, such as TiO 2 , ZnO, CdS, C 3 N 4 [255]. Cu(II)-porphyrin and TiO 2 nanoparticles into MOF structure (PCN-224(Cu)) leads to a marked improvement of light-harvesting features and promotes separation of photogenerated charges, reaching superior photocatalytic performance for CO 2 reduction [219,256].…”

Solar radiation is becoming increasingly appreciated because of its influence on living matter and the feasibility of its application for a variety of purposes. It is an available and everlasting natural source of energy, rapidly gaining ground as a supplement and alternative to the nonrenewable energy feedstock. Actually, an increasing interest is involved in the development of efficient materials as the core of photocatalytic and photothermal processes, allowing solar energy harvesting and conversion for many technological applications, including hydrogen production, CO2 reduction, pollutants degradation, as well as organic syntheses. Particularly, photosensitive nanostructured hybrid materials synthesized coupling inorganic semiconductors with organic compounds, and polymers or carbon-based materials are attracting ever-growing research attention since their peculiar properties overcome several limitations of photocatalytic semiconductors through different approaches, including dye or charge transfer complex sensitization and heterostructures formation. The aim of this review was to describe the most promising recent advances in the field of hybrid nanostructured materials for sunlight capture and solar energy exploitation by photocatalytic processes. Beside diverse materials based on metal oxide semiconductors, emerging photoactive systems, such as metal-organic frameworks (MOFs) and hybrid perovskites, were discussed. Finally, future research opportunities and challenges associated with the design and development of highly efficient and cost-effective photosensitive nanomaterials for technological claims were outlined.

“…[ 24,25 ] Constructing a C 3 N 4 /MOF heterojunction has been proved to be an effective strategy to overcome the drawbacks of both MOFs and CN, for enhancing photocatalytic performance. [ 26,27 ] For example, CN/ZIF‐8, [ 28 ] CN/MIL‐53(Al), [ 29 ] CN/MIL‐53(Fe), [ 30 ] and CN/MIL‐125(Ti) [ 31 ] have been developed for improving catalytic activity in CO 2 reduction, H 2 production, and Cr(VI) reduction, respectively. Unfortunately, the interfacial resistance restricts the interface transfer of the changer, [ 32,33 ] and the photogenerated electrons travel from the CB of CN to the surface reaction sites (metal cluster) via linker to cluster, which lengthens the distances for further proton reduction, increasing the probability of photoexcited electrons being undesirably trapped and reducing the photocatalytic efficiency.…”

Designing high‐efficiency photocatalysts with high charge separation and rapid charge transfer still a challenge. Herein, highly effective g‐C3N4/NH2–UIO‐66 (CNU) hybrids are developed using an engineered ZrN bond between the two components. The formation of the ZrN bond provides an electron transfer pathway between the conduction band (CB) of g‐C3N4 (CN) and Zr centers, which shortens the carrier migration distance, greatly enhancing the separation efficiency of photogeneration carriers. The as‐prepared CNU shows an outstanding performance for photocatalytic reduction of Cr(VI) under visible light irradiation due to the rapid charge carrier interfacial transfer. This work provides a promising strategy for the design of efficient photocatalysts and helps to establish an effective and sustainable method for removing Cr(VI) under ambient conditions.
