A {Cu}-added polyoxometalate cluster-organic framework: synthesis, structure and application as a solid support for enzyme immobilization.

A new two-dimensional {Cu6}-added polyoxometalate cluster-organic framework (Cu-POMCOF) was prepared by a hydrothermal method from lacunary polyoxoanions and was applied as a solid support for immobilizing MP-11 and Cyt c. The biocomposite complex exhibits higher stability and catalytic activity than the original free enzyme.

Two new Cu-based borate catalysts with cubic supramolecular cages for efficient catalytic hydrogen evolution.

Focusing on renewable energy, we are devoted to developping efficient, robust and low cost water reduction catalysts (WRCs). Two new Cu-based borate catalysts, namely HNaK[(μ-O)Cu@BO(OH)]·21HO (1) and HRbK[(μ-O)Cu@BO (OH)]·15HO (2), with cubic supramolecular cages were synthesized under a hydrothermal condition. Moreover, new copper complexes were applied as water reduction catalysts (WRCs) in the presence of [Ir(ppy)(dtbbpy)][PF] as photosensitizer and triethanolamine (TEOA) as the sacrificial electron donor.
