Metal–organic frameworks (MOFs), also known as porous coordination polymers (PCPs), synthesized by assembling metal ions with organic ligands have recently emerged as a new class of crystalline porous materials. The amenability to design as well as fine-tunable and uniform pore structures makes them promising materials for a variety of applications. Controllable integration of MOFs and functional materials is leading to the creation of new multifunctional composites/hybrids, which exhibit new properties that are superior to those of the individual components through the collective behavior of the functional units. This is a rapidly developing interdisciplinary research area. This review provides an overview of the significant advances in the development of diverse MOF composites reported till now with special emphases on the synergistic effects and applications of the composites. The most widely used and successful strategies for composite synthesis are also presented.

Complex Hydrides for Hydrogen Storage

Metal–organic frameworks (MOFs), established as a relatively new class of crystalline porous materials with high surface area, structural diversity, and tailorability, attract extensive interest and exhibit a variety of applications, especially in catalysis. Their permanent porosity enables their inherent superiority in confining guest species, particularly small metal nanoparticles (MNPs), for improved catalytic performance and/or the expansion of reaction scope. This is a rapidly developing interdisciplinary research field. In this review, we provide an overview of significant progress in the development of MNP/MOF composites, including various preparation strategies and characterization methods as well as catalytic applications. Special emphasis is placed on synergistic effects between the two components that result in an enhanced performance in heterogeneous catalysis. Finally, the prospects of MNP/MOF composites in catalysis and remaining issues in this field have been indicated.

Supramolecular chemistry.

This review focuses on classifying different types of long wavelength absorbing BODIPY dyes based on the wide range of structural modification methods that have been adopted, and on tabulating their spectral and photophysical properties. The structure–property relationships are analyzed in depth with reference to molecular modeling calculations, so that the effectiveness of the different structural modification strategies for shifting the main BODIPY spectral bands to longer wavelengths can be readily compared, along with their effects on the fluorescence quantum yield (ΦF) values. This should facilitate the future rational design of red/NIR region BODIPY dyes for a wide range of different applications.

The development of an inexpensive, more stable and efficient electrocatalyst for hydrogen evolution reaction in water splitting has become more challenging task for researchers in present scenario. In the present study, different morphologies of two rare earth based nanomaterials Gd 2 O 3 :GdPO 4 and Nd 2 O 3 :NdPO 4 were successfully made via simple one-step hydrothermal method and used as catalyst for hydrogen evolution reaction in acidic medium (0.5 M H 2 SO 4 ). The Nd 2 O 3 :NdPO 4 exhibited comparable catalytic activity with standard Pt/C electrode material in 0.5 M H 2 SO 4 . The obtained overpotential to achieve current density of 10 mA cm −2 for Nd 2 O 3 :NdPO 4 and standard Pt/C was 134 and 123.5 mV vs. RHE, respectively and their corresponding Tafel slopes were 55.6 and 52.5 mV.decade −1 , respectively. The efficient catalytic activity of the prepared catalyst was due to its unique surface morphology and strong interaction between the present elements. The turnover frequency was found as 0.00008637 and 0.00171 s −1 for Gd 2 O 3 :GdPO 4 and Nd 2 O 3 :NdPO 4 nanomaterials, respectively and their corresponding BET surface area were 14.9663 and 78.2404 m 2 g −1 . Based on literature reports and best of our knowledge, Nd 2 O 3 :NdPO 4 is an efficient novel catalyst and its electrocatalytic activity is not reported till date. • Rare earth based Gd 2 O 3 :GdPO 4 and Nd 2 O 3 :NdPO 4 synthesized via hydrothermal route. • The materials were characterized by different techniques and explored their HER activity. • Overpotential 123.5, 134 and 467 mV @ 10 mA.cm −2 for Pt/C, Nd and Gd-based catalyst, respectively. • Large TOF, ECSA, small charge transfer resistance, BET surface area of Nd-based catalyst.
