Abstract
A manganese based catalyst for use in a metal-air electrochemical cell wherein the catalyst is made by a sol-gel process. The sol-gel process creates catalyst particles that are submicron and easily distributed throughout the active layer of the electrode.
Claims7
A method of making a catalyst for use in an electrochemical cell, the method comprising:
- preparing a solution of a manganese alkoxide and alcohol;
- adding water to the solution to form a sol;
- heating the sol to a temperature sufficient to remove the alcohol and form a gel;
- mixing the gel with activated carbon;
- and
- heating the mixture of the gel and the activated carbon to a temperature sufficient to evaporate the water and form a manganese oxide catalyst.
