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.

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...

Engineering the nanostructures and compositions of 2D layered metal thiophosphates (MTPs) is significant for extending their applications. Here, a scalable and flexible strategy is presented to prepare single crystalline CoNiPS 3 incorporated with N-doped carbon (CoNiPS 3 /C) nanosheets (≈16 nm thickness), which can be further processed into the mosaicstructured CoNiPS 3 /C nanosheets (≈6 nm thickness) composed of randomly distributed crystalline nanodomains (≈15 nm diameter) and disordered boundaries (denoted as mosaic CoNiPS 3 /C nanosheets), and further into separated CoNiPS 3 /C nanodots (≈4 nm diameter). The initial CoNiPS 3 /C nanosheeets are prepared by using Co-Ni Prussian-blue analogue nanoplates as templating precursors. As compared to the initial CoNiPS 3 /C nanosheets and nanodots, the mosaic CoNiPS 3 /C nanosheets exhibit plenty of active edge sites, retained crystallinity, and good structural stability. Synergistically, density functional theory calculations reveal that the bimetallic composition results in higher intrinsic activity, better conductivity, and lower kinetic energy barriers for bifunctional oxygen/hydrogen evolution reactions. More importantly, a water-splitting electrolyzer constructed using the mosaic CoNiPS 3 /C nanosheets as both cathode and anode achieves 30 mA cm −2 at 1.62 V, which is better than the initial CoNiPS 3 /C nanosheets (1.69 V) and is comparable to the discreted nanodots (1.58 V). Besides, the mosaic CoNiPS 3 /C nanosheets show much better electrocatalytic stability than nanodots.and oxygen in large scale. [1][2][3][4][5][6][7] In order to achieve high energy conversion efficiency, the state-of-the-art electrolyzer usually needs highly active electrocatalysts to simultaneously lower energetic barriers of hydrogen/oxygen evolution reaction (HER/OER). However, since overall water splitting process is an uphill reaction, the commercial electrolyzer still requires a much higher operating voltage (≈2.0 V) than theoretical value (≈1.23 V) even with the costly Pt and IrO 2 or RuO 2 as the benchmark HER and OER electrocatalysts, respectively. [8][9][10][11][12][13][14][15] As such, developing highly efficient, stable, and cost-effective electrocatalysts for overall water splitting is of crucial importance to advance the prospects of this fascinating technology.Recently, various cost-effective transition metal based electrocatalysts have received considerable attention for HER and OER because of their environmentally benign nature and easy availability. [16][17][18][19][20][21] Particularly, lamellar metal thiophosphates (MTPs), a new family of ternary 2D nanomaterial, are emerging as highly attractive electrocatalysts due to the good activity, earth abundance, and compositional diversity. [5,20,[22][23][24][25][26][27] Despite advances in individual metrics for HER or OER through various strategies, [22,23,28,29] the performance of MTPs as bifunctional electrocatalysts for HER/OER is still far from satisfactory. According to the fundamental principles of HER/OER reactions, t...
