“…DFT calculations revealed that cobalt sites are favorable for receiving electrons from Zn porphyrin. [143] Therefore, the utilization of nickel-based or cobalt-based 2D materials in photocatalytic applications is not only attributed to the beneficial conductive properties and to the strong binding energy with H 2 and CO 2 , but also to the synergy with other metals; in this way, the overall photocatalytic performance of the materials can be enhanced. At the same time, the low dimensionality offers a shorter charge transport path and boosts light harvesting ability.…”

Ferromagnetism in 2D materials has attracted tremendous interest from the scientific community thanks to its potential for the design of magnetic materials with unique properties. The presence of a ferromagnetic element in a 2D material can improve the existing properties and offer new ones, giving rise to the development of manifold applications. This review focuses on recent advances and perspectives of 2D materials that bear at least one ferromagnetic element (iron, cobalt, nickel) as i) structural constituent, ii) dopant atom, or iii) adjacent atom through proximity effect. By describing in detail the magnetic properties that have emerged so far, their potential to form next‐generation 2D magnets is discussed. Moreover, the contribution of such 2D materials is analyzed in various applications (electrochemical, photochemical, optical, and electronic), aiming to explore further functionalities and capabilities of ferromagnetic elements, apart from their magnetic nature. Special attention is given to gadolinium and other rare earth elements that display a ferromagnetic order even at ultra‐low temperatures and form part of 2D structured materials, with particularly appealing properties deriving from their 4f electrons.

“…For example, photocatalytic CO 2 reduction can produce various fuels such as CO, formic acid, and hydrocarbons [ 103 ]. In recent years, MOFs have been widely studied for photocatalytic CO 2 reduction due to their adjustable composition and structure, easy integration with other functional substances, and large surface area [ 136 , 137 , 138 , 139 ].…”

Metal-organic frameworks (MOFs) are a novel category of porous crystalline materials with an exceptionally high surface area and adjustable pore structure. They possess a designable composition and can be easily functionalized with different units. Porphyrins with conjugated tetrapyrrole macrocyclic structures can absorb light from ultraviolet to visible light regions, and their structures and properties can be facilely regulated by altering their peripheral groups or central metal ions. Porphyrin-based MOFs constructed from porphyrin ligands and metal nodes combine the unique features of porphyrins and MOFs as well as overcoming their respective limitations. This paper reviewed the design and construction, light absorption and charge transfer pathways, and strategy for improving the photocatalytic performance of porphyrin-based MOFs, and highlighted the recent progress in the field of CO2 reduction, hydrogen evolution, organic synthesis, organic pollutant removal, and nitrogen fixation. The intrinsic relationships between the structure and the property of porphyrin-based MOFs received special attention, especially the relationships between the arrangements of porphyrin ligands and metal nods and the charge transfer mechanism. We attempted to provide more valuable information for the design and construction of advanced photocatalysts in the future. Finally, the challenges and future perspectives of the porphyrin-based MOFs are also discussed.

“…The porous architecture of this family of 2D-MOFs driven by the reticular chemistry of the metal centers and the organic linkers creates conducting channels and the π–π electron conjugation in the porphyrin ligands brings forth excellent electronic conductivity in these 2D materials. − The additional structural features of the 2D-MOFs include a larger surface area, conducive diffusion of gases in the framework, and mechanical stability. The metalloporphyrin MOFs have been reported as active electrocatalysts and photocatalysts for hydrogen evolution reaction (HER) and CO 2 RR (CO 2 reduction reaction), C–H activation, and nitrous oxide decomposition. − The extraordinary performance of metalloporphyrin MOFs in CO 2 RR, a multistep CO 2 reduction to CO and CH 4 as end products, prompted their application into electrocatalysts for nitrogen reduction reaction, which is a six-electron-reduction process.…”

Two-dimensional (2D) metal organic framework (MOF) or metalloporphyrin nanosheets with a stable metal-N 4 complex unit present the metal as a single-atom catalyst dispersed in the 2D porphyrin framework. First-principles calculations on the 3dtransition metals in M-TCPP are investigated in this study for their surface-dependent electronic properties including work function and dband center. Crystal orbital Hamiltonian population (-pCOHP) analysis highlights a higher contribution of the bonding state in the M−N bond and antibonding state in the N−N bond to be essential for N−N bond activation. A linear relationship between ΔG max and surface electronic properties, N−N bond strength, and Bader charge has been found to influence the rate-determining potential for nitrogen reduction reaction (NRR) in M-TCPP MOFs. 2D Ti-TCPP MOF, with a kinetic energy barrier of 1.43 eV in the final protonation step of enzymatic NRR, shows exclusive NRR selectivity over competing hydrogen reduction (HER) and nitrogenous compounds (NO and NO 2 ). Thus, Ti-TCPP MOF with an NRR limiting potential of −0.35 V in water solvent is proposed as an attractive candidate for electrocatalytic NRR.
