The invention discloses a kind of nitrogen oxygen sulphur three to adulterate porous carbon coating Co 9 S 8 Composite catalyst and preparation method thereof is related to composite catalyst and electro-catalysis technical field.The present invention selects terephthalic acid (TPA) and 4 cheap and easy to get, two thiobis (4 of 4'-(sulfo group, 1- phenylene)) two pyridines, two kinds of ligands with cobalt nitrate have constructed three foreign atom mixed matching cobalt-based metal-organic framework materials (writing a Chinese character in simplified form are as follows: Co-MOF) of nitrogen oxygen sulphur, and VPO catalysts are produced by a kind of compound electro-catalysis of precursor preparation of Co-MOF, it is used for efficient electrolysis aquatic products oxygen.In 1.0 mol L ‑1 Potassium hydroxide electrolyte in, when current density reaches 10 mA cm ‑2 When, overpotential for oxygen evolution is 330 mV, has lower analysis oxygen overpotential.And the catalyst is still able to maintain higher catalytic activity after long-time constant potential (1.58 V) electrolysis, there is stronger stability, practical application value with higher. |
