摘要：

New electrochemical sensors developed for the quantitative analysis of near-ppm levels of hydrogen and hydrogen sulfide are reported. They combine existing electrochemistry and new regeneratable electrode materials incorporated in a simple design. The operation principle is oxidation of the gas molecules on a sensitive platinum electrode connected with a counter electrode based on macrocyclic or macrobicyclic polyaza cobalt(III) complexes as the catalysts. The sensors show good linearity and selectivity, comparatively high sensitivity (0.1 ppm H2S), perfect stability and an extremely long operating life of up to several years.
