Methods and apparatus for electrochemical extraction of a ligand such as molecular oxygen from a first fluid environment and for release of a ligand such as molecular oxygen, as well as ligand carrier compounds therefor comprising linear, pentadentate polyalkylamines and transition metal ions. The carrier compounds have the general formula:
where:
M is an electrochemically active transition metal ion;
R, and R2 are each organic groups including a nitrogen coordinated to M;
m, n, o, and p are each 1, 2, 3, or 4; and
X is selected from the group consisting of 2,6-pyridyl, 2,6-piperidyl, 2,5-pyrrolyl, 2,4-imidazolyl, substituted heterocyclic amines, -O-, -S-, -P-, and -N-R, where R is hydrogen lower alkyl, or aralkyl.
By providing an electrocatalyst capable of rapid electron transfer and having an electropotential less than that of the carrier compound, low energy electron transfer between the carrier compounds and the electrode of the electrochemical cell is achieved. The use of electrodes having catalytically active surface sites leads to efficient electron transfer between the carrier compounds and the electrodes of the electrochemical cell, resulting in lower energy consumption and/or increased oxygen output.
