Abstract

Abstract : A high-nuclearityCd24 cluster built from Cd4 -thiacalix[4]arene SBUs and in situ generated peroxyphosphate PO5 3− exhibited significant photocatalytic water splitting activity in absence of a co-catalyst. Abstract : A high-nuclearity nanoscaleCd24 cluster has been hydrothermally synthesized by assembly of Cd4 -TC4A (H4 TC4A = p-tert -butylthiacalix[4]arene) second building units (SBUs) and in situ generated peroxy(mono)phosphate PO5 3− groups and peroxyphenoxide groups of TC4A. The cluster was structurally characterized by single crystal X-ray diffractions. Photocatalytic studies revealed that the highest nuclearity Cd, S-co-richCd24 cluster exhibits enhanced photocatalytic water splitting activities compared to the sandwichCd4 (TC4A)2 (Cd4 ) cluster under the same conditions in the absence of a co-catalyst. The nanostructure ofCd24 incorporated both peroxyphosphate and peroxyphenoxide groups, which increased the metal coordination numbers to give more labile Cd–O/S bonds and is believed to be the key feature that enables the significant photocatalytic water splitting activities.
