Metal–organic framework-derived photoelectrochemical sensors: structural design and biosensing technology

“…Metal-organic frameworks (MOFs) have intriguing properties such as large surface area, tailored pore size, exclusive topology, structural diversity, and exposed active sites. 1,2 Taking the structural advantages, MOFs have been demonstrated for their feasibility in practical applications involving gas storage and separations, 3,4 pervaporation, 5 heterogeneous catalysis, [6][7][8] optoelectronic sensing, 9 and theranostics treatment. [10][11][12] It is noteworthy that the inherent porosity makes MOFs a demanding candidate in reliable molecular recognition and high-performance sensor applications.…”

“…Metal organic framework (MOF) materials have a huge specific surface area, adjustable pore structure and pore size, and good structural stability, which make them widely used in the fields of pollutant adsorption and degradation, 17 fluorescence recognition sensing, 18 AOPs, 19 catalysis, 20,21 photocatalysis, 22 etc. MOFs have also been considered as promising photocatalysts applied in photo-Fenton-like systems due to their excellent semiconductor property and photoelectric conversion performance.…”

Sulfur-modulated metal–organic framework MIL-101(Fe) with CQDs anchored as an efficient light-driven photocatalyst: photocatalytic performance and mechanism investigation

“…22,29 MOF materials have unique performance advantages, such as controllable pore size and modified pore surface, low density, high surface area, possibility to be functionalized and environmental stability, and thus this new type of porous material has been widely used in many fields, for example, adsorption, 30 photocatalysis, 31,32 catalysis, 33,34 drug delivery, gas storage and purification 35 and sensing. 36,37 The organic ligands of MOFs are good antennas for light adsorption for the production of photocarriers via LMCT pathways and their iron clusters act as abundant active sites, 38 and thus they are appealing for application in photocatalysis. 39 However, some drawbacks still hinder their application such as wide band gap, UV-restricted activation and severe recombination of photo-induced electrons and holes.…”
