Aufgrund ihrer speziellen physikalischen und chemischen Eigenschaften stehen zweidimensionale (2D‐)Schichtmaterialien im Fokus der aktuellen materialwissenschaftlichen Forschung. Dies schließt Schichten ein, die aus einem einzelnen Element (Graphen, Phosphoren), zwei Elementen (Metall‐Dichalkogenide) oder mehreren Elementen bestehen. Die erstmals im späten 19. Jahrhundert synthetisierten Metall‐Phosphor‐Trichalkogenide (MPCh3 mit Ch=S, Se) bilden eine besondere Klasse von 2D‐Schichtmaterialien. MPCh3‐Verbindungen, die in den 1970er Jahren wegen ihres ungewöhnlichen Interkalationsverhaltens in Bezug auf ihre magnetischen Eigenschaften sowie als Sekundärelektroden in Lithium‐Batterien untersucht worden waren, wurden erst vor kurzem als 2D‐Nanomaterialien wiederentdeckt. Zahlreiche aktuelle Berichte über MPCh3 für die Wasserspaltungskatalyse und Energiespeicherung werden umfassend erörtert, wobei der Fokus auf der Synthese dieser Materialien und ihren wesentlichsten Eigenschaften liegt. Dieser Kurzaufsatz soll als Ausgangsbasis für die Erkundung solcher 2D‐Schichtmaterialien für elektrochemische Energieanwendungen dienen.

Single crystal sheet of layered material, FePS 3 , grows inside sealed and evacuated silica tube. The FePS 3 forms at 650°C under a controlled heating rate. X-ray diffraction (XRD), Scanning electron microscope (SEM) and transmission electron microscope (TEM) have been used to study the crystal structure and morphology. The XRD pattern exhibits sharp 001 reflections of the single crystal alloy sheet. The prepared samples exhibit high thermal stability with a decomposition temperature of 780 ˚C. The SEM images show smoothness of the single crystal sheets. Corrosion behavior was investigated by using open circuit potential, Tafel polarization and cyclic voltametry in presence of 10% hydrochloric acid. The crystal open circuit potential shifts to the nobler direction. There is a passive region in the anodic branch of the polarization curve. The presence of the passive region reflects high corrosion resistance. This behavior of high corrosion resistance can be rationalized on the basis that single crystals are free from grain boundaries. INTRODUCTIONSingle crystal is the perfect structure of crystalline materials. It is free of grain boundaries. This behavior increases its corrosion resistance. However, there are few methods for preparing bulk single crystals. MnPS 3 single crystals were grown from a powder mixture of Mn, P and S [1, 2]. Transition metal chalcogenophosphates or layered materials, MPX 3 (M ≡ transition metals; X ≡ S or Se) show fascinating structure, electric and magnetic properties [3][4][5][6]. The structure of these materials is closely related to that of the well-known transition metal dichalcogenide, MX 2 [7][8][9]. They have been applied in many fields such as nonlinear optical materials, magnetic materials, photomagnetic materials, catalytic materials, medical and biomedical materials and cathode materials in the rechargeable batteries [10][11][12][13][14]. The layered materials, especially, FePS 3 , MnPS 3 and MgPS 3 , were investigated for hydrogen storage application and the results were promising [15][16][17]. Physical properties and characterization of such materials were extensively studied [18][19][20][21][22][23]. The electrochemical characteristics of the MPS 3 and NiPS 3 as cathodic materials in room temperature lithium batteries were investigated [24]. The theoretical specific capacities of a family of layered compounds MPX 3 (M = Fe, Co, Ni; X = S, Se) involving 1.5, 2, 6 and 9 lithium atoms per MPX 3 molecule have been estimated [25]. The data show that FePS 3 and NiPS 3 are good electroactive materials for primary lithium cells [26]. This work aims at studying growth of single crystal of the FePS 3 layer material under vacuum conditions. The single

The exponentially growing works on 2D materials have resulted in both high scientific interest and huge potential applications in nanocatalysis, optoelectronics, and spintronics. Of especial note is that the newly emerged and promising family of metal phosphorus trichalcogenides (MPX 3 ) contains semiconductors, metals, and insulators with intriguing layered structures and architectures. The bandgaps of the members in this family range from 1.3 to 3.5 eV, significantly enriching the application of 2D materials in the broad wavelength spectrum. In this review, emphasizing their remarkable structural, physicochemical, and magnetic properties, as well as the numerous applications in various fields, the innovative progress on layered MPX 3 crystals is summarized. Different from other layered materials, these crystals will advance a fascinating frontier in magnetism and spintronic devices with their especially featured atomic layered nanosheets. Thus, their crystal and electronic structures, along with some related researches in magnetism, are discussed in detail. The assortments of growth methods are then summarized. Considering their potential applications, the prominent utilization of these 2D MPX 3 nanoscrystals in catalysis, batteries, and optoelectronics is also discussed. Finally, the outlook of these kinds of layered nanomaterials is provided. Metal Phosphorus Trichalcogenidesions. Friedel [17] and Ferrand [18,19] discovered them in the late 1800s. Based on the interesting structure of these materials, significant research works were reported in the early 2000s. As expected, 2D MPX 3 phases share most of the abovementioned specific properties of 2D TMDs. According to the theoretical and experimental results, MPX 3 compounds are the most sought functional materials for their intermediate bandgaps ranging from 1.3 to 3.5 eV, [20,21] indicating their enhanced light absorption efficiency as compared to the TMD materials. In addition, their unusual intercalation-substitution or intercalation-reduction behavior as well as the incipient ionic conductivity promote their usage in Li-ion batteries, [22,23] gas storage, [24] and photo-electrochemical reactions. [25] Unlike TMDs, several MPX 3 materials show intrinsic anti-ferromagnetism below the Neel temperatures of 78 K for MnPS 3 , 116 K for FePS 3 , and 155 K for NiPS 3 . [26,27] Recently, Li et al. [28] predicted that transformation from the anti-ferromagnetism to ferromagnetism for exfoliated MnPSe 3 nanosheet will be reduced by carrier doping. And the Monte Carlo simulation reveals the Curie temperature of the doped MnPSe 3 nanosheets can reach 206 K, rendering it with potential for utilizations in spintronic devices at high temperature. Therefore, the members in the MPX 3 family have the abovementioned properties along with structural flexibility stemming from their van der Waals nature; thus, it is reasonable to assume that they will contribute to the next major frontier in 2D vdW layered materials.Herein, we emphasize on reviewing the impressive recent progress...
