I am working on a route to develop phase pure MAX phases but as with all MAX phase synthesis the formation fo binary carbides hinders this. For some mechanical testing i would like some phase pure samples and thought in the mean time if it was possible to etch away the binary carbide and work with a porous MAX phase that would be fine.
I have found one paper previously that has done this but i cannot locate it anymore with the influx of papers on formation of MXENEs.
Any help would be greatly appreciated
