Creating nanomaterials called metal-organic frameworks through the traditional process is a tedious and expensive procedure which could also cause damage to the environment. However, these nanomaterials are some of the most versatile and durable so we cannot eliminate or stop its production.
So researchers designed a new method of producing these MOFs through sound waves.
During the standard production process, solvents and other contaminants become trapped in the MOF's holes. To flush them out, scientists use a combination of vacuum and high temperatures or harmful chemical solvents in a process called "activation".
In their novel technique, RMIT researchers used a microchip to produce high-frequency sound waves. Using the sound waves to arrange and link these elements together, the researchers were able to create a highly ordered and porous network, while simultaneously "activating" the MOF by pushing out the solvents from the holes.
