“…The edges and the so‐called grain boundaries of 2D crystals are particularly active since they possess dangling bonds, which differ them from the rest of the crystal. 2D materials and metal‐organic networks can also serve as a matrix for incorporating catalytically active sites such as transition metal active centers [70,71,72] . For instance, FeN 4 can be embedded into the graphene layer [71] .…”

“…2D materials and metal-organic networks can also serve as a matrix for incorporating catalytically active sites such as transition metal active centers. [70,71,72] For instance, FeN 4 can be embedded into the graphene layer. [71] In such structures, these single atom centers are stabilized by covalent bonding with the rest of the 2D lattice, while remaining coordinatively unsaturated, which keeps them catalytically active.…”

A sustainable future demands a successful transition from a carbon energy-dependent economy towards renewable energy schemes, many of which ultimately rely on the development of efficient electrocatalysis that either converts chemical energy into electricity or uses electrons to produce chemical energy. In general, electrocatalysis studies focus on the interactions (e. g., electron transfer) between the catalyst surface and the reaction intermediates. However, the role of electron spin, as an intrinsic property of electrons, has commonly been overlooked. Recently, controlling the electron spin polarization at the catalyst's surface demon-strated the great potential of boosting both reaction activity and product selectivity. Molecule-induced electron spin polarization inspired by the chiral-induced spin selectivity (CISS) effect has started to have a remarkable impact in electrocatalysis. In this compact review, we summarize the latest studies that use molecule-induced electron spin polarization to enhance catalytic performance. We focus on the reactions essential to the so-called hydrogen economy, and discuss the feasibility and limitations of this effect. Finally, we share our perspective regarding the more impactful future applications.

“…[17][18][19] In fact, the spin state of the Mn ion in the tetra-pyrrolic pocket may sweep across different configurations by subtle modification of the N ligand field, e.g., by changes of the Mn-ligand distance (HS in Mn-porphyrins, 20 IS in Mn-Pc 15 ) or of the ligand peripheral coordination (HS in Mn-TCNQ 4 metal-organic covalent networks). 21 Interestingly, it has been recently demonstrated that ruthenium tetraphenylporphyrin (RuTPP) on Ag(111) can be stabilized in two different conformations, saddle-shaped and planar, and only the former may axially interact with CO as a consequence of its greater molecular flexibility. 22 As such, the role played by the molecular flexibility in prompting the electronic and magnetic properties of TMTPP after electron doping is an essential aspect whose potential applications are not yet sufficiently investigated.…”
