Summary: Two phosphorus-containing ruthenium complexes were synthesized and characterized spectroscopically and electrochemically. Both complexes exhibited proton-coupled electron transfer (PCET) behavior. A Ru(V/IV) couple was detected at 1.4 V vs. NHE for [Ru(bpyPO(3)H(2))(bpy)Cl]Cl. The complexes were tested for their ability to catalyze C-H bond oxidation and it was found that [Ru(bpyPO(3)H(2))(bpy)Cl]Cl can oxidize secondary C-H bonds using NaIO4 as the primary oxidant under aqueous conditions.

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%.

Summary: Nanozyme based sensors have been developed as an effective method for detecting harmful metal ions in water samples. In this study, a Co(II) based coordination polymer nanoparticle (Co-CP NP) was synthesized and utilized as a nanozyme to detect Fe(II) ions selectively. The Co-CP NP exhibited peroxido-reductase mimicking activity, and the detection limit for Fe(II) ions was found to be 0.66 μM. The catalytic action of the Co-CP NP was further analyzed using Michaelis-Menten kinetics, and the detection mechanism was elucidated through XPS and zeta potential analysis.
