Nano-Ru deposited on titanium dioxide as effective photocatalyst for synthesis of cyclic ketals for application as fuel biocomponents
We designed and synthesized the 1–4 % Ru/TiO2 system as a cost-efficient acetalization catalyst for polyol-ketone reactants without the additional acidic or organic co-solvent addition. The catalyst was characterized using EDXRF, XPS, XRD, TEM, UV-Vis/DR and TOF-SIMS techniques. The 2 % Ru/TiO2 catalyst proved to be the most active in a model reaction with photo assistance, exhibiting the highest TON value of 5272. This outcome underscores the synergistic activation achieved by combining ruthenium and titania. More detailed analysis reveals a dual mechanism, wherein photocatalytic oxygen vacancy formation in TiO2 plays a crucial role. This mechanism involves the continuous vacancy feeding by the reactant oxygen. Additionally, we tested the selected cyclic ketals as the 95-octane gasoline additives as bio-additives, aligning with current legal regulations and contributing to a reduced carbon footprint.
期刊介绍：
Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications.
Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
