“…S20-S22, ESI †), which proved that compounds 1 and 2 have good structural stability and reusability, and may act as photocatalysts in industrial applications. According to the literature, 7,22 the photocatalytic mechanism of compounds 1 and 2 in organic dye molecule degradation is similar to that of reported photocatalysts. Irradiated by UV light, electrons (e À ) will be excited from the valence band to the conduction band, leaving holes (h + ) in the valence band (Fig.…”

“…[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Also their potential application as photocatalysts for degrading organic dye molecules is well recognised. [22][23][24][25][26] The photocatalytic process of active MOF-based catalysts can be considered as an effective method for the degradation of organic dyes, because they can mineralize the synthetic organic dyes to the smallest components, such as CO 2 , H 2 O, etc. [27][28][29] For example, MOF-5, which is composed of Zn 4 O clusters and connected by 1,4-benzenedicarboxylic acid ligands, was proposed to behave as a photocatalyst and resulted in the decomposition of phenol under UV irradiation.…”

The expanding population and technological advancements are driving the energy demand. The overuse of conventional petroleum fossil fuels has resulted in large emissions of greenhouse gases, which cause global warming and other problems. Controlling carbon dioxide emissions is therefore essential to reducing greenhouse impact. Among the numerous benefits of metal-organic frameworks (MOFs) are their high porosity and vast interior surface area. They are now the most promising adsorbent materials and have a wide variety of applications in the adsorption and separation of gases, including carbon dioxide. To address the mechanical, chemical, thermal, and water stability of MOFs, this article first provides an overview of their structure and synthesis design techniques. Next, this article addresses the selectivity of MOFs for nitrogen and water as well as the adsorption process of CO2 in MOFs. The techniques for modifying MOFs, such as pore size-controlled MOFs, targeted metal unit modification, and functional group modification to improve adsorption and separation performance, were highlighted last.

Solar-driven photocatalysis has shown great potential as a sustainable wastewater treatment technology that utilizes clean solar energy for pollutant degradation. Consequently, much attention is being paid to the development of new, efficient and low-cost photocatalyst materials. In this study, we report the photocatalytic activity of NH4V4O10 (NVO) and its composite with rGO (NVO/rGO). Samples were synthesized via a facile one-pot hydrothermal method and successfully characterized using XRD, FTIR, Raman, XPS, XAS, TG-MS, SEM, TEM, N2 adsorption, PL and UV‒vis DRS. The results indicate that the obtained NVO and NVO/rGO photocatalysts exhibited efficient absorption in the visible wavelength region, a high content of V4+ surface species and a well-developed surface area. Such features resulted in excellent performance in methylene blue photodegradation under simulated solar light illumination. In addition, the composite of NH4V4O10 with rGO accelerates the photooxidation of the dye and is beneficial for photocatalyst reusability. Moreover, it was shown that the NVO/rGO composite can be successfully used not only for the photooxidation of organic pollution but also for the photoreduction of inorganic pollutants such as Cr(VI). Finally, an active species trapping experiment was conducted, and the photodegradation mechanism was discussed.
