Аннотация
The structures of nanocrystalline pristine, potassium hydroxide and sodium acetate intercalated new two-dimensional materials ${\mathrm{Ti}}_{3}{\mathrm{C}}_{2}$ MXenes were studied using the x-ray atomic pair distribution function technique. Pristine MXene has a hexagonal structure with $a=b=3.0505(5)\text{ }\text{ }\AA{}$, $c=19.86(2)\text{ }\text{ }\AA{}$ (S.G. $P{6}_{3}/mmc$ No. 194). Both hydroxyl and fluoride terminating species are present. The intercalation of ${\mathrm{K}}^{+}$ or ${\mathrm{Na}}^{+}$ ions expands the ${\mathrm{Ti}}_{3}{\mathrm{C}}_{2}$ layers perpendicular to the planes but shrinks the in-plane $a$ and $b$ lattice parameters.
