Rie Makiura, Associate Professor at the Graduate School of Engineering, Osaka Metropolitan University, published an overview study on the straightforward synthesis of nanosheet materials provided with high-precision nanoscale holes.
Nanosheets, which are two-dimensional materials with a nanometer-scale thickness (10-6 mm), have gained interest as extremely thin functional units that can be used to reduce material consumption and miniaturize goods.
Metal-organic frameworks (MOFs) are porous materials having carefully specified nanoscale pores of varying sizes and shapes. They specialize in molecular adsorption, segregation, and specific molecular recognition.
Their greater surface area contrasted to that of traditional materials such as activated carbon and silica gel gives them the ability to be high-performance adsorbents. MOFs can serve a multitude of purposes and are now being researched for use as parts in a variety of sectors, such as the delivery of drugs and catalytic applications.
High-performance gas separation membranes and gas sensors are anticipated to benefit from the availability of MOFs in nanosheet form, yet, creating efficient synthesis processes for MOF nanosheets has proven to be a considerable hurdle up to this point.
By dropping a component material solution onto the water’s surface, a research team directed by Professor Makiura was able to create the first MOF nanosheets ever; the findings were published in a journal in 2010.
More than 600 citations have been made to the discovery’s publication due to the widespread interest it has received from researchers. Using the same technique, the team has also successfully produced the organic nanosheets known as hydrogen-bonded organic frameworks (HOF) in 2017 and MOF nanosheets, which conduct electricity in 2021.
The properties of the many MOF nanosheets described by researchers worldwide and their comparison, as well as their creation method on the water surface, are all thoroughly covered by Professor Makiura in her current review study.
I feel honored to be given the opportunity to publish this review article as a leading researcher in the field. I hope this review article will accelerate technological progress in the application of MOF nanosheets to separation membranes and in the miniaturization and performance enhancement of sensors.
