“…In order to obtain the heat capacity at pressure constant as a function of temperature, we use the SIESTA software to calculate the forces required as input used in PHONOPY software [23]. This software is based on the quasi-harmonic approximation used for thermal expansion, and then heat capacity is obtained.…”

Magnetism in atomically thin two-dimensional (2D) materials is attractive for several applications such as memory devices, sensors, biomedical devices, etc. Here, we have synthesized 2D manganese telluride (MnTe) using a scalable synthesis method consisting of melting followed by liquid phase exfoliation (LPE). Both bulk and 2D MnTe samples were analyzed for their magnetic behavior at room temperature and low temperatures (10 K). A change from antiferromagnetic nature to paramagnetic behavior was observed in 2D MnTe flakes. Enhanced magnetic saturation values (up to 400% increase) were observed as compared to bulk MnTe in RT. Density functional theory (DFT) simulations explain the layer-dependent magnetic behavior of the 2D MnTe flakes, as well the antiferromagnetic to paramagnetic transition due to an unbalanced spin population.

“…The degrading efficiency of magnetic metal tellurides was therefore boosted by the synergistic effect of the magnetic field and light irradiation. It was well known that both the separation of photo‐generated carriers and the reverse reaction of the products are crucial for increasing the efficiency of photocatalytic activity [44] . As high‐performance intercalation‐type electrode materials for energy storage devices, TMDs have gained a lot of interest.…”

Chalcogenides are more frequently used to refer sulfides, selenides, tellurides and polonides rather than oxides and all the elements in group 16 of the periodic table are chalcogens. The synthesis of transition metal chalcogenides (TMCs) and their composites involved a wide range of techniques like one pot heat up, hydrothermal, solvothermal, precipitation, co‐precipitation and biological procedures. In light of the possibility of photo‐induced charge‐transfer events leading to intra‐ensemble charge separation, the integration of TMCs onto a strong electron‐accepting material such as graphene which provides unique TMC/graphene consisted of great significance. Electrochemical water splitting is a promising technology for converting, storing and transporting hydrogen energy in a sustainable manner. Because of their unique physical and chemical properties, as well as their low cost, transition metal chalcogenides are fascinating replacements for catalysts in catalytic water splitting. Transition metal chalcogenides have worldwide attention in recent decades due to their applications in chemical sensors, biological and environmental monitoring applications from biosensors to therapeutic treatment agents.

“…[10][11][12] In view of the above two problems, magnetic field, with the non-contact and environmentally friendly nature, attracts increasing attention as an emerging method for providing new and lasting power for CO 2 capture and conversion. [13,14] CO 2 is a typical quadrupole molecule and its adsorption is supposed to be affected by the external field. Magnetic field has been introduced into separation processes in the chemical industry [15] and also employed to facilitate the adsorption of CO 2 by magnetic nanoparticles, [16] which all played a non-negligible role in CO 2 capture and catalytic conversion.…”

CO2 capture and conversion technology are highly promising technologies that definitely play a part in the journey towards carbon neutrality. Releasing CO2 by mild stimulation and the development of high efficiency catalytic processes are urgently needed. The magnetic field, as a thermodynamic parameter independent of temperature and pressure, is vital in the enhancement of CO2 capture and conversion process. In this review, the recent progress of magnetic field‐enhanced CO2 capture and conversion is comprehensively summarized. The theoretical fundamentals of magnetic field on CO2 adsorption, release and catalytic reduction process are discussed, including the magnetothermal, magnetohydrodynamic, spin selection, Lorentz forces, magnetoresistance and spin relaxation effects. Additionally, a thorough review of the current progress of the enhancement strategies of magnetic field coupled with a variety of fields (including thermal, electricity, and light) is summarized in the aspect of CO2 related process. Finally, the challenges and prospects associated with the utilization of magnetic field‐assisted techniques in the construction of CO2 capture and conversion systems are proposed. This review offers a reference value for the future design of catalysts, mechanistic investigations, and practical implementation for magnetic field enhanced CO2 capture and conversion.
