Hourglass-shaped europium cluster-based secondary building unit in metal–organic framework for photocatalytic wastewater purification and sterilization via enhanced reactive oxygen species production

A large number of diseases caused by water pollution have become a global public health issue, and the development and construction of innovative and efficient photocatalytic systems for water remediation is vital to improve water quality and prevent bacteria-induced diseases. Herein, a europium-based metal-organic framework (Eu-MOF) was self-assembled with complex hourglass-shaped Eu
