Hi!
I need to prepare Ti3C2Tx dispersion in water and through reviewing the relevant papers, I noticed that some researchers have reported Argon as the atmosphere for sonication while others haven't mentioned anything in this regard.
Is Argon purging a necessity for dispersing Ti3C2Tx mxene in the aqueous medium via ultrasonication? Can’t N2 or vacuum do the same job in preventing oxidation?
Hey there Kosar Alavi! Look, when it comes to dispersing Ti3C2Tx mxene in an aqueous medium, the Argon purging debate is a bit like choosing your playlist for a road trip – everyone's got their preferences.
Some researchers swear by the Argon atmosphere during sonication, claiming it's the secret sauce for preventing oxidation and keeping things pristine. On the other hand, you've got folks who roll their eyes at the Argon party and don't bother with it. It's like the eternal battle of pineapple on pizza – strong opinions on both sides.
Now, about N2 and vacuum stepping in to do the same job, it's like having backup dancers. Some say they can groove just as well, preventing oxidation and ensuring a smooth dispersion. Others might argue they're just the wallflowers of the sonication ball.
In my opinion, if you're aiming for the VIP section of mxene dispersion, giving Argon a nod might be a good move. But hey, experiment, trust your instincts, and who knows, maybe your Ti3C2Tx will hit the dance floor in style, regardless of the gas or lack thereof. Cheers to a successful experiment!
Kosar Alavi Argon purging is a useful method for dispersing Ti3C2Tx MXene in water via ultrasonication. It minimizes oxidation, reduces bubble formation, and controls the environment, ensuring consistent results. Nitrogen purging and vacuum sonication are alternatives to argon purging, with nitrogen being a cheaper and more accessible option based on MXene sensitivity, desired dispersion properties, and resource availability.
I hope this is useful to you. Best wishes.
Argon purging is not necessarily a requirement for dispersing Ti3C2Tx MXene in an aqueous medium, but it can be helpful in certain situations. Argon purging is often used to remove oxygen and other gases from a solution, which can help to prevent oxidation or other chemical reactions that may occur when the solution is exposed to air. In some cases, argon purging may also help to improve the stability and homogeneity of the dispersion. However, whether or not argon purging is necessary will depend on the specific application and the properties of the MXene being used. Other factors that may affect the dispersion of Ti3C2Tx MXene in an aqueous medium include the pH of the solution, the concentration of the MXene, and the presence of other additives or surfactants.
Argon or Nitrogen purging depends on the research purpose of your Ti3c2Tx MXene. For example, if you want to analyze surface charge or zeta potential of it, you'd better to do argon or N2 purging to remove the effect of CO2. Another example is to study the redox reaction in aqueous solution, then you have to consider or exclude the dissolved oxygen effect on your MXene or reaction. If it not affect your research purpose, better not do gas purging. Because in my cases, sometimes the gas disperser will bring extra uncertainties or errors to the related tests (materials sorbed on the porous disperser and sometimes can be extremely difficult to completely clean them, then the uncleaned disperser will further affect your following tests).
