Abstract: Aspects disclosed herein include a system for generating singlet oxygen in a gas, the system comprising: a substrate; and hexanuclear clusters operably immobilized on at least a portion of the substrate; wherein each hexanuclear cluster comprises a photosensitive octahedral core complex characterized by formula FX1a: M6X8 (FX1a); wherein each M is independently Mo, W, or Re; wherein each X is independently a halide anion ligand; wherein the clusters are exposed to the gas and the gas comprises O2 gas; wherein the clusters are exposed to a light; and wherein each hexanuclear cluster is a photosensitizer configured to generate the gaseous singlet oxygen when irradiated by the light in the presence of the O2 gas.

Abstract: Provided herein are processes and systems for oxidation of a hydrocarbon reactant to generate an oxidized hydrocarbon product; said process comprising: contacting a water oxidation electrocatalyst with said hydrocarbon reactant and water in the presence of a non-aqueous solvent; wherein an anodic bias is applied to said water oxidation electrocatalyst, thereby generating said oxidized hydrocarbon product; and wherein said water oxidation electrocatalyst comprises one or more transition metals other than Ru. Optionally, said water is provided in said non-aqueous solvent at a concentration less than or equal to 0.5 vol. %. Optionally, the magnitude of said anodic bias is selected to generate said oxidized hydrocarbon product characterized by selected product distribution.
