Abstract

A new calixarene-supported bimetallic coordination cluster (NH 4 ){Co 4 II (TC4A)Cl[(Mo V O 2 ) 2 S(CH 3 O)] 4 } (+solvent) (abbr. Co 4 Mo 8 , H 4 TC4A = p-tert-butylthiacalix[4]arene) was obtained by a solvothermal reaction. Co 4 Mo 8 features a sulfur modified polyoxometalate Mo 8 cluster capped by a Co 4 -TC4A unit. Co 4 Mo 8 clusters directly fabricated on nickel foam (NF) were used as working electrodes, giving drastically improved electrocatalytic activities for the oxygen evolution reaction (OER) with an overpotential of 302.8 mV at 10.0 mA cm -2 in basic media. Upon replacing Co in Co 4 Mo 8 clusters with Ni or Zn, component controlled investigations indicated that the extraordinary OER performance originated from the Co-Mo synergistic effect. Furthermore, the deliberately incorporated sulfur atoms at the lower rim of Co 4 Mo 8 clusters facilitated the adherence between the clusters and NF, resulting in a binder-free electrocatalyst with efficient and ultra-stable OER performance (366.8 mV at 40.0 mA cm -2 for more than 150 hours).
