Polyoxometalate-based metal-organic complexes (POMOCs) which combine the structural features and performance advantages of MOCs and POMs, have a wide application in the field of catalysis. However, the catalytic capacity of POMOCs commonly cannot be fully utilized due to their imporosity and low surface area of single-crystals. In this work, a new POMOC with a formula of [Cu₃O(4-atrz)₆(PO₃)(PMo₁₂O₄₀)] (POMOC 1, 4-atrz = 4-amino-4H-1,2,4-triazole) was synthesized. And the size regulation of POMOC 1 from single-crystal to nanoscale was achieved by using citric acid as a modulator and adjusting the reaction temperature. Nano-sized POMOC 1 exhibited excellent catalytic performance in the oxidation reaction of phenols owing to the synergistic catalysis of POM and coordinatively unsaturated Cu(Ⅱ), and more surface-accessible catalytic sites of nano-catalyst.
