Here, we propose UV light illumination as an alternative approach to tune the active phase under reaction conditions.

Furthermore, using operando Fourier transform infrared spectroscopy under CO<sub>2</sub> hydrogenation conditions, we observed a light-induced change in surface coverage of different species, such as CO*, (bi)carbonates and formates. When switching between dark and light conditions, a reversible increase in activity was observed, accompanied by a decrease in the IR absorption bands of formates and CO*. We propose that the reduction of cobalt is due to a charge transfer mechanism from the conduction band of the titania support to the conduction band of the cobalt metal (oxide) nanoparticles. On the other hand, we attribute CO desorption to a metal-to-ligand charge transfer, from the d-band of the cobalt metal (oxide) nanoparticles to the adsorbed CO molecules. While UV light illumination is more commonly used to enhance catalytic performance, we demonstrate its application to tune the active phase of the catalyst, offering advantages over conventional methods that suffer from undesired effects, like metal (oxide) nanoparticle sintering.</div></div>","PeriodicalId":66,"journal":{"name":"Catalysis Science & Technology","volume":"16 10","pages":"Pages 3508-3519"},"PeriodicalIF":4.0,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148011632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cyclic hydrogenation/dehydrogenation of liquid organic hydrogen carriers (LOHCs) such as benzyltoluene (BT) provides a pathway to simultaneously store hydrogen and purify such “low-grade” hydrogen feeds. In this context, Ni-based catalysts are particularly attractive because they can hydrogenate aromatic systems under CO-containing atmospheres while representing a relatively cheap alternative to noble metal catalysts. Here, we systematically investigate BT hydrogenation over a commercial Ni/Al<sub>2</sub>O<sub>3</sub>/SiO<sub>2</sub> catalyst under process-relevant LOHC conditions (<em>T</em> = 170–230 °C, <em>p</em> = 10–50 bar) in the presence of CO (0–6%) and demonstrate that BT conversion remains feasible even at high CO levels, while the hydrogenation rate decreases due to competitive CO adsorption. Time-resolved analysis of both gas- and liquid-phase compositions further reveals CO methanation during BT hydrogenation, indicating that both reactions proceed in parallel while competing for active sites. By varying temperature and total pressure, the balance between BT hydrogenation and methanation can be steered, with 230 °C and 50 bar identified as the most favorable conditions for efficient BT hydrogenation under CO presence. In addition, introducing CO<sub>2</sub> at biomass-typical concentrations (30 vol%) shows that it likewise adsorbs competitively on Ni and is also converted to methane. Collectively, these results highlight Ni-based catalysts as a robust catalyst for mixed-gas hydrogenation and LOHC-enabled purification/storage of biogenic hydrogen, while underscoring an inherent trade-off between competitive (co-)methanation, that consumes a fraction of hydrogen as CH<sub>4</sub> that cannot be recovered upon LOHC dehydrogenation, yet constitutes an energy-dense coproduct stream that may be valorized.</div></div>","PeriodicalId":66,"journal":{"name":"Catalysis Science & Technology","volume":"16 10","pages":"Pages 3609-3620"},"PeriodicalIF":4.0,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148011670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
