Abstract In the realm of energy conversion and storage devices, transition metal porous oxide composites have been subject extensive research interest. Supercapacitors electrocatalysis, as two important modalities, exhibit a competitive yet balanced relationship, much like state equilibrium. this work, comprehensive reduction approach is employed during pyrolysis anionic/cationic doped molecular clusters, specifically [Zn 7 L 6 ( μ 3 ‐OCH ) ]·[CoCl 4 ] (where = 2‐methoxy‐6‐((methylimino)‐methyl)phenolate, abbreviated Zn Co 1 ). Notably, within an inert atmosphere, significant quantity diverse range reducing gases are generated throughout entire temperature spectrum , monitored by thermogravimetry‐mass spectrometry (TG‐MS). It observed that production these led to in valence oxides, thereby inducing shift electrochemical behavior from oxygen evolution supercapacitive performance at different temperatures. The ‐350 sample demonstrated reaction (OER) performance, with overpotential 168 mV current density 10 mA·cm −2 . Conversely, ‐700 exhibited excellent capacitance attaining 1406 F·g −1 A·g findings offer novel synthesis clusters electrical capabilities via total strategy.
