Selective Etching of Silicon from Ti3SiC2 (MAX) To Obtain 2D Titanium Carbide (MXene)

Abstract: Until now, MXenes could only be produced from MAX phases containing aluminum, such as Ti AlC . Here, we report on the synthesis of Ti C (MXene) through selective etching of silicon from titanium silicon carbide-the most common MAX phase. Liters of colloidal solutions of delaminated Ti SiC -derived MXene (0.5-1.3 mg mL ) were produced and processed into flexible and electrically conductive films, which show higher oxidation resistance than MXene synthesized from Ti AlC . This new synthesis method greatly widens… Show more

“…In a recent study, to economically produce Ti 3 C 2 on a large scale, Alhabeb et al. synthesized 2D Ti 3 C 2 from Ti 3 SiC 2 for the first time in various solutions containing HF and H 2 O 2 . The products had the same structures as those derived from Ti 3 AlC 2 .…”

“…Inherited from the MAX phases, the 2D M n+1 X n layers also have hexagonal symmetry and in analogy to graphene, which has hexagonal symmetry, they have been named MXenes. Over [3,27,28,29,30,31,32,33].…”

“…However, the use of strong fluoride‐based solutions may cause safety and handling concerns and usually leads to over‐etching. Therefore, further optimization of etching conditions is necessary . Recently, an organic base, tetramethylammonium hydroxide (TMAOH), was used to selectively etch the amphoteric Al layer in Ti 3 AlC 2 .…”
