“…To avoid the damage to samples resulting from significant swelling, an extra 2 wt % of KCl power, which can prevent the swelling of the bedding plane, was added into the brine. The saline sandstone aquifer from which the sample was cored is located in the Ordos Basin, China, and has a depth of about 2700 m and a geothermal gradient of 4 °C/100 m. 50 The temperature at the aquifer's depth is about 130 °C. As for the saturation system with confining pressure, it was first heated to 130 °C and kept unchanged for 12 h to generate a uniform temperature environment.…”

A good understanding of CO2–brine–rock interactions that cause microscale damage to the microstructure of sandstone, affecting pore fluid transport and reservoir stability, is important for studying storage efficiency during CO2 storage. In this study, the equipment is first designed to saturate rock samples using CO2–brine under in situ conditions and then the homogeneous and heterogeneous sandstone samples are saturated for 30 days with and without the confining pressure (20 MPa). Through scanning electron microscopy (SEM) observation and analysis, it is found that the confining pressure reduces the degree of damage in various scales from micrometer to millimeter, such as reducing the mineral dissolution, decreasing the induced swelling of the bedding planes, and causing some pores to collapse. The nuclear magnetic resonance results show that the change in porosity is mainly caused by the increase in the number of relatively small-sized (characterized in terms of fluid relaxation time T 2 < 10–3 s) pores after CO2–brine saturation. In addition, the alterations of the pore system in homogeneous and heterogeneous sandstones are different, such as a larger increase in the porosity of homogeneous sandstone (by 5.29%). In heterogeneous sandstone, the effect of mineral dissolution induced by chemical reactions on damaging the microstructure is more obvious than mineral swelling. In addition, it is found that the CO2–brine saturation decreases the fractal dimension of the sandstone by nearly 2%, increasing the pore connectivity. This study is helpful for understanding the evolution of the sandstone microstructure under geological conditions during the long-term CO2 storage process.

“…[76,77] Despite having a smaller radius than bare ZIF-67, Au-20/ZIF showed less capacity to inject hot charge carriers, which agrees with photocatalytic activity. [78,79] To elucidate that Au PNPs can improve the separation of light-triggered charge carriers in ZIF-67, photoluminescence (PL) spectroscopic study was performed at an excitation wavelength of 560 nm. The photoluminescence studies of bare ZIF- show a weaker signal compared to ZIF-67 (black), which indicates that Au PNPs greatly reduced the electron-hole recombination.…”

The design of functionalized metallic nanoparticles is considered an emerging technique to ensure the interaction between metal and semiconductor material. In the literature, this interface interaction is mainly governed by electrostatic or van der Waals forces, limiting the injection of electrons under light irradiation. To enhance the transfer of electrons between two compounds, close contact or chemical bonding at the interface is required. Herein, a new approach was reported for the synthesis of chemically bonded plasmonic Au NPs/ZIF-67 nanocomposites. The structure of ZIF-67 was grown on the surface of functionalized plasmonic Au NPs using 1H-1,2,4-triazole-3thiol as the capping agent, which acted as both stabilizer of Au nanoparticles and a molecular linker for ZIF-67 formation. As a result, the synthesized material exhibited outstanding photocatalytic CO 2 reduction with a methanol production rate of 2.70 mmol h À 1 g À 1 cat under sunlight irradiation. This work emphasizes that the diligent use of capping agents, with suitable functional groups, could facilitate the formation of intimate heterostructure for enhanced photocatalytic CO 2 reduction.

“…In a similar approach, Wang et al synthesized a hierarchical core-shell Cu 7 S 4 @ZIF-8 composite for cyclo-condensation reaction. [40] Under laser irradiation, the localized heat generated from the plasmonic Cu 7 S 4 nano-heaters is efficiently transferred to the catalytic ZIF-8 shell, resulting in a 4-fold enhancement of the catalytic activity compared with the thermal catalysis. Recently, Jing et al reported the photo-thermal carboxylation of terminal alkynes with CO 2 under visible light irradiation at room temperature using a Ag@MIL-100(Fe) composite.…”

The direct utilization of light to drive chemical reactions has been considered a promising approach to decarbonizing the chemical industry and storing solar energy in the form of chemical bonds. In this regard, photo-thermal catalysis has emerged as a bright strategy due to the combination of thermal and non-thermal contributions of sunlight. This enables the whole exploitation of the solar spectrum providing localized heating and thus an enhancement in the productivity rates. In this scenario, MOFs and MOFs-derived materials offer great opportunities for the rational design of new photo-thermal catalysts. In this review, we describe the different types of photo-thermal systems, with a particular consideration on the mechanisms. Further, we describe the recent advances of MOF and MOF-derived materials as photo-thermal catalysts for different catalytic reactions, including organic transformations, pollutant degradation or CO 2 hydrogenations. Lastly, we present our opinion on the future challenges and perspectives in the field.
