MnPS 3 powder was used as obtained from the solid reaction and grinding procedure. The exfoliation process was based in alreadyreported works of intercalation 17 and exfoliation 18 of MnPS 3 plus a sonication step with probe sonicator. In this procedure 300 mg of MnPS 3 powder was mixed with 25 mL of 3 M KCl aqueous solution and let stirring for 1 hour. The second step was centrifuging the mixture for removing the excess of K + ions. Then, the solid was collected, mixed with 20 mL of 2 M LiCl aqueous solution and let stirring overnight.
