Summary: The development of peptide-metal frameworks as proteomimetic materials has been limited by the restricted choice of side chains and few variable residues compatible with metal ions. In this study, a noncovalent strategy using g-stacking bipyridyl residues was developed to assemble longer peptides into crystalline frameworks. These materials exhibited proteomimetic behaviors and could be optimized for increased affinity towards complex organic molecules.

Summary: The immobilization of polyoxometalates (POMs) near catalytic centers of metal-organic frameworks (MOFs) has been reported to enhance the photocatalytic activity for strategic reactions such as CO2 reduction (CO2RR) or hydrogen evolution (HER). The role of encapsulated POMs in boosting the activity of Rh-functionalized MOF towards CO2RR and HER has been elucidated using theoretical and experimental approaches. The encapsulated POMs act as efficient electron reservoirs, quenching the photogenerated reduced form of the photosensitizer and transferring the electrons to the Rh catalytic sites, thereby favoring the regeneration of the oxidized photosensitizer and increasing the turnover numbers of the photocatalytic system. The redox potentials of POMs play a crucial role in determining the activity of the POM-containing catalytic materials.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
