Advances in Titanium Carbide (Ti3C2Tx) MXenes and Their Metal–Organic Framework (MOF)-Based Nanotextures for Solar Energy Applications: A Review

“…Here, electrons migrate from the CB of Cu 2 O to the LUMO of Co-MOF, whereas the holes from HOMO of Co-MOF transfers to the VB of Cu 2 O, achieving good spatial separation of charge carriers. Additionally, the formation of heterojunctions drastically improved the visible light adsorption of pristine Cu 2 O, as shown in the UV–vis diffuse reflectance spectra in Figure b . In another study, a Z-scheme heterojunction system (Figure c) was achieved over PCN-224­(Cu)/TiO 2 photocatalysts which improved the overall photocatalytic reaction .…”

“…Additionally, the formation of heterojunctions drastically improved the visible light adsorption of pristine Cu 2 O, as shown in the UV−vis diffuse reflectance spectra in Figure 16b. 189 In another study, a Z-scheme heterojunction system (Figure 16c) was achieved over PCN-224(Cu)/TiO 2 photocatalysts which improved the overall photocatalytic reaction. 190 Surface sensitization is achieved when the Schottky junction is formed upon introduction of metals.…”

Paddle-Wheel-Shaped Porous Cu(II)–Organic Framework with Two Different Channels as an Absorbent for Methylene Blue

“…Metal–organic frameworks (MOFs) are porous crystalline materials made by coordinated metal ions/clusters with organic ligands. They can be employed in a variety of application aspects, including gas adsorption or separation, − drug delivery, catalysis, − and so forth, owing to high specific surface areas, high porosity, chemical adaptability, and active sites . Though there are broad application prospects in the field of adsorption, the investigations of MOF applications are focused more on gas treatment than on wastewater treatment.…”

Dye-Anchoring Strategy with a Metal–Organic Framework for a Highly Efficient Visible-Light-Driven Photocatalytic CO2 Reduction through the Solid–Gas Mode

“…Metal–organic frameworks (MOFs) are a well-known class of crystalline micro/mesoporous hybrid materials constructed by metal ions/clusters interconnected with multidentate organic ligands. − Benefiting from their high surface area, porous structure, and high-density coordination-unsaturated metal sites, MOFs have been widely employed in various applications such as gas adsorption and separation, heterogeneous catalysis, sensing, CO 2 capture, and conversion. − MOFs can be conveniently tailored to achieve isostructural materials with an extra optical absorption range and an enhanced CO 2 adsorption capacity by postsynthetic modifications. In particular, MOFs have been demonstrated as novel photocatalysts due to their unique advantages, such as the high-density metal/ion active sites, adjustable light-harvesting ligands, improved electron–hole separation, and so on.…”
