Abstract:

A new sulfonylcalix[4]arene-supported tetrahedral Co16 cage cluster [Co16(TC4A-SO2)4(OH)4·(L)8][(C8H20N)(C4H12N)2(C2H8N)]·solvent(Abbr. Co16-TC4A-SO2) was synthesized from CoCl2·6H2O, p-tert-butylsulfonylcalix[4]arene(H4TC4A-SO2) and asymmetric 3-(1H-tetrazol-5-yl)benzoic acid(H2L) under solvothermal condition. The complex was characterized by single crystal X-ray diffraction(XRD), powder X-ray diffraction(PXRD), thermogravimetric analysis(TGA), and infrared spectroscopy(FTIR). Directly loading Co16-TC4A-SO2 onto carbon paper(Co16-TC4A-SO2/CP) as a working electrode exhibited efficient oxygen evolution reaction(OER) catalytic performance. In 1 mol/L KOH, Co16-TC4A-SO2/CP gained a current density of 10.0 mA/cm 2 at a catalytic reaction overpotential of 343.8 mV, a Tafel slope of 79.31 mV/dec, and catalytic stability for 48 h at 20.0 mA/cm 2.
