Metal organic framework-based Janus nanomaterials: rational design, strategic fabrication and emerging applications

Abstract

Janus MOFs holds a novel strategy in overcoming the shortcomings of conventional metal–organic frameworks (MOFs) as well as non-porous Janus nanoparticles by exhibiting non-centrosymmetry and multi-functionality.

Inner transition metal-modulated metal organic frameworks (IT-MOFs) and their derived nanomaterials: a strategic approach towards stupendous photocatalysis

“…1,2 Owing to the synergistic effect of both their metal nodes and organic linkers, MOFs and their derivatives are suitable candidates for a wide range of solar light-illuminated catalysis. 3–5 In fact, in the last several years, the increase in reports on MOFs in the literature has provided diverse framework structures, which are fabricated using various metals as metal nodes and diverse categories of polytopic linkers such as cationic, anionic, and neutral linkers as another building block of the framework. 6,7…”

[3][4][5] In fact, in the last several years, the increase in reports on MOFs in the literature has provided diverse framework structures, which are fabricated using various metals as metal nodes and diverse categories of polytopic linkers such as cationic, anionic, and neutral linkers as another building block of the framework. 6,7 Additionally, MOFs possess a designable pore structure, high surface area (∼7800 m 2 g −1 ), free volume (∼90%), and low density (∼0.124 g cm −3 ), making them superior to related materials such as conventional nanomaterials, zeolites, and 1D-coordination polymers.…”

Hyperdispersed ruthenium nanoparticles anchored on S/N co-doped carbon nanotubes as an efficient HER electrocatalyst

“…For example, heteroatoms (N, S, P, and B) can change the electronic properties and adjust the energy band structure of graphene materials; this change of electronic properties and the energy band greatly extends the application of graphene based materials. [13][14][15][16] Carbon nanotubes can be seen as curled graphene sheets, and carbon atoms are also sp 2 hybridised.…”

“…For example, heteroatoms (N, S, P, and B) can change the electronic properties and adjust the energy band structure of graphene materials; this change of electronic properties and the energy band greatly extends the application of graphene based materials. 13–16 Carbon nanotubes can be seen as curled graphene sheets, and carbon atoms are also sp 2 hybridised. Their excellent electronic conductivity and thermal conductivity, strong mechanical strength and large specific surface area make them widely used in hydrogen storage, transistors, field emission devices, nonlinear optics, lithium-ion batteries and supercapacitors.…”

Editorial: Biodegradable Polymers for Biomedical Applications

“…In addition to the biomedical materials mentioned by Bao et al, Janus particles also have great potential in cancer prevention. Janus particles are non-centrosymmetric colloidal materials with non-centrosymmetric shape, composition, and behavior (Tripathy et al, 2022). Because of the changeable dimension, biocompatibility, and low toxicity of Janus particles, these are widely employed in biomedical disciplines, notably in tumour prevention (Zhao et al, 2009).…”
