Connecting Titanium-Oxo Clusters by Nitrogen Heterocyclic Ligands to Produce Multiple Cluster Series with Photocatalytic H2 Evolution Activities

We herein demonstrate the ability of nitrogen heterocyclic ligands in connecting polyoxotitanium complexes into crystalline multiple cluster series. Moreover, their bandgap and photocatalytic water-splitting behavior were studied. The highest H-2 evolution activity reaches up to 42.80 mu mol g(-1) h(-1) for PTC-46.
