Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a tetraazaannulene cobalt complex compound (hereinafter referred to Co-TAA) useful as an oxygen reduction catalyst and a method for the preparation of the Co-TAA.
2. Description of the Prior Art
Various kinds of oxygen reduction catalysts have been known. Especially, platinum has been well known as an oxygen reduction catalyst because of the superior catalytic properties. However, it is difficult to practically employ platinium as a catalyst in a fuel battery because platinum is expensive and a rare metal. Therefore, the development of new catalysts having a low oxygen reduction voltage and a high catalytic activity have been desired and made. However, the catalysts which can take the place of platinum have not been found.
The Co-TAA having the formula (VII); ##STR2## is reported as an oxygen reduction catalyst having a high activity in F. Beck et al, Z. Naturforsch. 28a, 1009-1021(1973), and DE-OS No. 20 46 354. However, the catalyst life of the Co-TAA of the formula (VII) is short and, in addition, the catalyst activity is not satisfactory.
Further, the Co-TAA having the formula (VIII); ##STR3## is reported in Y. Nishida et al, Bulletin of the Chemical Society of Japan, Vol. 50(9), 2485-2486 (1977). There is no description relating to the oxygen reduction catalyst properties of the Co-TAA of the formula (VIII) in the report. The inventors of this invention have produced the Co-TAA of the formula (VIII) to measure the catalytic properties, and found that the catalyst activity is insufficient though the catalyst life is long.
A method for the preparation of the Co-TAA is described in Y. Nishida et al, Journal of Coordination Chemistry, Vol. 9, 161-166 (1979). This method, however, has a defect that the reaction procedures and the aftertreatments are difficult due to the use of sulfur and acetyl hydroperoxide in the production of the starting material, that is, dithiolium hydrogensulfate. Further, this method has such defects that the yields of the tetraazaannulene and the Co-TAA are low, that the purity of the Co-TAA is also low and that the purification of the Co-TAA is difficult.
SUMMARY OF THE INVENTION
An object of this invention is to provide a novel Co-TAA.
Another object of this invention is to provide a novel method for preparing the Co-TAA including conventional Co-TAA, and a tetraazaannulene derivative which is an intermediate of the Co-TAA.
Accordingly, this invention provides a novel Co-TAA having the general formula (I); ##STR4## wherein R.sub.1, R.sub.2 and R.sub.3 each independently is a hydrogen atom, a C.sub.1-8 alkoxy group or a C.sub.1-8 alkyl group but in case of one of R.sub.1, R.sub.2 and R.sub.3 being a hydrogen atom the other two groups are not hydrogen atoms at the same time, and when R.sub.1 is a methyl group R.sub.2 and R.sub.3 are not hydrogen atoms at the same time.

EXAMPLE 210
The oxygen reduction catalyst activities of Co-TAA as obtained in Examples 1, 3, 8, 19, 93, 96, 126, 140, 154, 168, 188 and 198 were measured. The measurement was carried out in accordance with the cyclic voltammetry method by using a potentiostat.
In 1 l of chloroform of 1 l of N,N-dimethylformamide was dissolved 800 mg of Co-TAA, and in the solution was dipped a Glassy Carbon (trade name; product of Tokai Denkyoku Seizo K.K.) whose surface was mirror-plane finished for 30 minutes. The Glassy Carbon was taken out from the solution and left to stand to dryness. The treated glassy carbon was employed as a cathode electrode. A platinum coil was employed as an anode electrode and a calomel electrode was employed as a reference electrode. An electrolytic solution was 1N sulfuric acid and the measurement temperature was 25.degree. C.
The measurement was carried out by introducing a high-purity oxygen gas into the electrolytic solution and recording the electric current generated by varying the voltage from +800 mV to -600 mV at a velocity of 25 mV/sec.
The catalyst activity was evaluated by the generated electric current value at +375 mV. The measurement was repeated 10 times and the catalyst life was evaluated by the tenth measurement result, that is, the tenth catalyst activity. The measurement results are shown in Table 2.

COMPARATIVE EXAMPLE
The catalyst activity and the catalyst life of Co-TAA having the formula (VII) were measured by the same methods as those of this invention. The Co-TAA has a catalyst activity of 145 .mu.A/cm.sup.2 and a catalyst life of 30 .mu.A/cm.sup.2.
