A cerium-based metal-organic framework was prepared using cerium ions and a nitrilotribenzoic acid linker through a hydrothermal approach. The resulting material combines cerium Lewis acid sites with triphenylamine cores, demonstrating Fenton-like catalytic behaviour. It effectively catalyses the oxidation of olefins and alcohols, achieving complete conversion of cinnamyl alcohol to benzaldehyde and a fifty-three percent conversion of styrene with seventy-five percent selectivity for styrene oxide. Additionally, the framework works alongside hydrogen peroxide to degrade hazardous organic dyes, specifically rhodamine B, methyl blue, Congo red, and direct blue. Mechanistic testing confirmed that this degradation relies on the generation of reactive hydroxyl radicals within advanced oxidation processes. Furthermore, the solid catalyst retains its performance across at least five successive cycles of reuse.
Industrial manufacturing and textile processing frequently generate toxic wastewater containing synthetic dyes and hazardous chemical residues. Catalysts that provide Fenton-like oxidation offer an efficient route to break down these pollutants while also enabling targeted chemical manufacturing. A durable, reusable material that facilitates both fine chemical production and environmental remediation supports cleaner industrial operations and safer water treatment.
The research could enable improved advanced oxidation systems for wastewater management and fine chemical synthesis. Potential users include chemical manufacturers producing oxidised intermediates and industrial facilities treating dye-laden effluent. With reusability demonstrated across five cycles, the technology has established basic laboratory viability, but it remains an early-stage catalyst requiring pilot-scale testing and validation under real-world effluent conditions before commercial adoption.

Abstract A metal–organic framework (MOF) of cerium (Ce) ions and 4,4′,4′′-nitrilotribenzoic acid linker was synthesized via a hydrothermal method. Ce-MOF consists of a Lewis acid moiety, i.e. Ce 3+ and triphenylamine cores. It showed Fenton-like properties with excellent catalytic oxidation activity for olefins, primary/secondary alcohols, and water pollutants e.g., organic dyes. It displayed high oxidation conversion of cinnamyl alcohol and styrene of 100% and 53%, respectively. It offered good selectivity towards styrene oxide and benzaldehyde (i.e. 75% and 100%, respectively). It was applied for the oxidative degradation of dyes e.g. rhodamine B (RhB), methyl blue (MeB), Congo red (CR), and direct blue (DB) using hydrogen peroxide (H 2 O 2 ) as an oxidant. It exhibited high efficiency in the oxidative degradation of these water pollutants. The mechanistic study of oxidation involves the formation of radical hydroxyl ( • OH) species. This study revealed the possibility of enhancing the oxidative catalytic performance, including oxidative degradation of organic pollutants, by employing advanced oxidation processes (AOPs) using Ce-MOF. The catalyst is recyclable five times without significantly decreasing of the material’s catalytic performance.
