Summary: This study describes a substrate oxidation reaction catalyzed by [Fe-II(IndH)(CH3CN)(3)](ClO4)(2) with H2O2, involving a spectroscopically characterized intermediate capable of olefin epoxidation and alkane hydroxylation. The research identified a direct nucleophilic attack of the substrate carbonyl group by the peroxo species. Additionally, the study found that the high-valent iron-oxo oxidant derived from O-O bond cleavage of the peroxo intermediate contributes to the oxidative reactivities associated with nonheme diiron enzymes.

Summary: A new multicomponent reaction involving isocyanide, alkynes, and endohedral metallofullerene (EMF) Lu3N@C-80 has been developed to yield metallofulleroids characterized by various analytical techniques. Single crystal studies revealed ordered Lu3N cluster in one ketenimine metallofulleroid, which is rare for EMF monoadducts. Computational analysis confirmed that the motion of the endohedral cluster is influenced by the position of exohedral organic appendants.

Summary: In this study, a novel ZnSnO3 perovskite catalyst was developed for the highly selective and stable electrosynthesis of H2O2 via 2e-ORR. The catalyst exhibited excellent electrochemical activity and H2O2 selectivity, with a stable performance over 6 hours. Compared to the commercial Pt/C catalyst, ZnSnO3 perovskite showed a significantly higher turnover frequency (TOF), indicating its great potential as a non-noble metal oxide electrocatalyst for 2e-ORR.

Summary: This study presents a less destructive and efficient tooth whitening strategy using low-concentration hydrogen peroxide, enhanced by the catalytic activity of oxygen-deficient TiO2 nanoparticles. The photothermal-enhanced Fenton-like performance of the TiO2-x-based system shows great promise in tooth bleaching and potentially other biomedical applications.

Summary: FeOx supported on activated carbon is an ideal catalyst for catalytic wet peroxide oxidation (CWPO) due to its high activity and stability. This study investigated the contribution of different components in the catalyst and their corresponding reaction mechanism. It was found that carboxylic groups and Fe2O3 can activate H2O2 to generate ·OH radicals. The stability of the catalyst was also improved as the reaction progressed, with an increase in carboxylic groups and the size of Fe2O3 particles.
