Method for the Synthesis of Metal Cyanometallates

摘要

Methods are presented for synthesizing metal cyanometallate (MCM). A first method provides a first solution of AXM2Y(CN)Z, to which a second solution including M1 is dropwise added. As a result, a precipitate is formed of ANM1PM2Q(CN)R·FH2O, where N is in the range of 1 to 4. A second method for synthesizing MCM provides a first solution of M2C(CN)B, which is dropwise added to a second solution including M1. As a result, a precipitate is formed of M1[M2S(CN)G]1/T·DH2O, where S/T is greater than or equal to 0.8. Low vacancy MCM materials are also presented.

1. A method for synthesizing metal cyanometallate (MCM), the method comprising:
providing a first solution of AXM2Y(CN)Z;
where “A” is selected from a first group of metals including alkali and alkaline earth metals;where M2 is selected from a second group of metals including transition metals;where x is in a range of 0 to 10;where Y is in a range of 1 to 10;where z is in a range of 1 to 10; dropwise adding a second solution including M1 to the first solution;
where M1 is selected from the second group of metals; forming a precipitate of ANM1PM2Q(CN)R.FH2O;
where N is in a range of 1 to 4;where P is less than or equal to 2;where F is in a range of 0 to 20;where Q is less than or equal to 2; and,where R is less than or equal to 6.
