Carbon monoxide dehydrogenases and formate dehydrogenases efficiently catalyze the reduction of CO. In both enzymes, CO activation at the metal active site is assisted by proximate amino acids and Fe-S-clusters. Functional features of the enzyme are mimicked in molecular catalysts by redox-active ligands, acidic and charged groups in the ligand periphery, and binuclear scaffolds.

Effective degradation of non-natural phosphate triesters (PTs) widely used in pesticides and warfare agents is of paramount relevance for human and environmental safety, particularly under acidic conditions where they are highly stable. Here, we present a detailed reactivity and mechanistic study pioneering discrete {ZrO} clusters, which are commonly employed as building blocks for Zr-MOFs and as non-classical soluble coordination compounds for the degradation of PTs using the pesticide ethyl paraoxon as a model. Combined computational studies, mechanistic experiments, and EXAFS analysis show that the reactivity of these clusters arises from their Zr-Zr bimetallic sites, which hydrolyze ethyl paraoxon under acidic conditions through an intramolecular pathway.

Article Synopsis
- Photocatalytic conversion of methane (CH4) to methanol (CH3OH) offers a sustainable way to use natural gas and reduce greenhouse gases, but low-temperature synthesis presents challenges.* -
- Researchers developed a biomimetic photocatalyst with Fe2O3 nanoclusters and single Fe atoms on carbon nitride, achieving a high methanol production rate of 5.02 mmol·gcat-1·h-1 and a 98.5% selectivity for methanol.* -
- The study found that the combined function of Fe2O3 and single Fe atoms creates a dual-Fe site that efficiently activates oxygen and enhances the oxidation of methane, aided by light excitation for better reaction kinetics
