“…Such unique structural and compositional features make MOF-based materials promising for a wide range of applications, such as gas storage and separation, catalysis, sensors, and drug delivery. [25][26][27][28][29] Low-dimensional (LD) nanomaterials are of particular interest due to their anisotropic-tunable properties, which greatly influence their performances. [21][22][23][24] Similar to the size-dependent properties which are wellknown for nanomaterials, reducing size of MOF crystals may bring enlarged specific surface area and increased density of active sites for MOFs, leading to improved performance.…”

Low‐dimensional metal–organic frameworks (LD MOFs) have attracted increasing attention in recent years, which successfully combine the unique properties of MOFs, e.g., large surface area, tailorable structure, and uniform cavity, with the distinctive physical and chemical properties of LD nanomaterials, e.g., high aspect ratio, abundant accessible active sites, and flexibility. Significant progress has been made in the morphological and structural regulation of LD MOFs in recent years. It is still of great significance to further explore the synthetic principles and dimensional‐dependent properties of LD MOFs. In this review, recent progress in the synthesis of LD MOF‐based materials and their applications are summarized, with an emphasis on the distinctive advantages of LD MOFs over their bulk counterparties. First, the unique physical and chemical properties of LD MOF‐based materials are briefly introduced. Synthetic strategies of various LD MOFs, including 1D MOFs, 2D MOFs, and LD MOF‐based composites, as well as their derivatives, are then summarized. Furthermore, the potential applications of LD MOF‐based materials in catalysis, energy storage, gas adsorption and separation, and sensing are introduced. Finally, challenges and opportunities of this fascinating research field are proposed.

Graphene decorated MoS₂for eosin Y-sensitized hydrogen evolution from water under visible light

et al. 2017

Some two-dimensional nanomaterials, such as graphene and molybdenum disulfide, are presently being intensively investigated due to their excellent and unique performances. In the field of photocatalysis, MoS 2 is considered as a promising alternative to noble metal Pt for the hydrogen evolution reaction (HER). However, its poor electrical conductivity restricts its catalytic activity in the HER. In this work, MoS 2 was modified with graphene (G) by a simple hydrothermal method. The prepared G/MoS 2 composite was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results show that graphene modification does not influence the crystal phase of MoS 2 , but makes the latter more dispersed. The HER performance of G/MoS 2 was evaluated using eosin Y (EY) as a photosensitizer, and triethanolamine (TEOA) as a sacrificial electron donor under visible-light irradiation (l > 420 nm, 250 W high pressure Hg lamp as light source).The EY sensitized G/MoS 2 composite displays enhanced hydrogen evolution in terms of not only activity but also stability. The average HER activity (9.1 mmol h À1) is three times that of EY sensitized pure MoS 2 over 10 h. It is believed that the incorporation of graphene enhances the charge transfer ability and retards the self-degradation path of EYc À , ultimately improving the HER.

In recent years, two-dimensional (2D) graphitic carbon nitride (g-C3N4) has elicited interdisciplinary research fascination among the scientific communities due to its attractive properties such as appropriate band structures, visible-light absorption, and high chemical and thermal stability. At present, research aiming at engineering 2D g-C3N4 photocatalysts at an atomic and molecular level in conquering the global energy demand and environmental pollution has been thriving. In this review, the cutting-edge research progress on the 2D/2D g-C3N4-based hybrid nanoarchitectures will be systematically highlighted with a specific emphasis on a multitude of photocatalytic applications, not only in waste degradation for pollution alleviation, but also in renewable energy production [e.g., water splitting and carbon dioxide (CO2) reduction]. By reviewing the substantial developments on this hot research platform, it is envisioned that the review will shed light and pave a new prospect for constructing high photocatalytic performance of 2D/2D g-C3N4-based system, which could also be extended to other related energy fields, namely solar cells, supercapacitors, and electrocatalysis.
