Two‐Dimensional Layered Materials as Catalyst Supports

Abstract

Since the successful isolation of graphene, two-dimensional (2D) materials have attracted immense interest in contemporary chemical research owing to their unique structural and chemical properties with potentials cientific applications. Layered2 Dm aterials show differentc haracteristics from bulk 3D materials owing to significanta lterations in their electronic and structural behavior.F rom the last decade, 2D materials including grapheneh ave been extensively investigated as supports for metal nanoparticles (NPs) exhibiting excellent catalytic activity towards various chemical and electrochemical reactions.T his review focuseso nt he recent advances of graphene and other 2D layered materials as catalyst supports, their interactions with metal precursors, and catalytic applications. The catalytic behavior of metal NPs supported on 2D materials has been discussed regarding various electrochemical oxidation and reduction reactions in fuel cells as wella sn umerous organic reactions and catalytic hydrogen generation from the dehydrogenationo f hydrogen storagem aterials. We appraise that the catalytic behavior of the nanomaterials can be improved by simply modifying the interactions between precursors and supports by changing the chemical and physical properties of the support materials. Finally,w es ummarize the review with an outlooko nf uture opportunities and challenges of 2D materials to provide access to av ariety of low-costa nd high-performance catalysts in terms of both academic and industrial applications.

Development of Effective Catalysts for Hydrogen Storage Technology Using Formic Acid

“…[81,82] Nevertheless, the synthesis of ultrafine MNPs on graphene is still challenging. Of special note, considering the unique properties of hydrophilicity and large surface area of its precursor, graphene oxide (GO), graphene is very promising for immobilizing MNPs.…”

Bimetallic Pd96Fe4 nanodendrites embedded in graphitic carbon nanosheets as highly efficient anode electrocatalysts

“…59 Interestingly, 2D carbon nanosheets with graphene-like layered structure materials possess high electrical conductivity, a large number of active sites and high effective surface area, which make them ideal as an electrocatalyst support. 60,61 Many advanced techniques, including activation, helium ion bombardment, the template method, mechanical/chemical exfoliation, chemical vapour deposition, etc., have been developed to fabricate carbonaceous nanosheets but establishing an efficient and facile synthesis methodology for 2D porous carbon nanosheets would be of great benet for their large scale production. [62][63][64][65] Mesocarbon microbeads (MCMBs) are one of the commercially available conducting carbon materials with good thermal and chemical stability and high crystallinity that are widely utilized for cost-effective electromagnetic interference shielding application, supercapacitors, and as an anode material in lithium-ion batteries and a supporting material for fuel cell applications.…”

Metal Nanoparticles Anchored on Rhenium Disulfide Nanosheets as Catalysts for the Reduction of Aromatic Nitro Compounds

“…Among 2D nanomaterials, graphene is one of the widely scrutinized 2D materials as a catalyst and as a catalyst support in catalytic reactions while modified with metal NPs to achieve a good catalytic activity ,. Beyond graphene, transition metal dichalcogenides (TMD) such as MoS 2 , WS 2 , ReS 2 , MoSe 2 , etc.…”
