However, its efficacy is often limited by ineffective photocarrier separation. This study addresses these limitations by designing Janus-like type photocatalysts comprising silver (Ag) and gold (Au) nanoparticles anchored on hollow TiO₂ microspheres (HTMs) via a photoreduction method. The resulting composite photocatalysts, Ag/HTMs and Au/HTMs, were evaluated for their ability to degrade microplastic polyethylene (PE) films. Morphological and compositional analyses using SEM, EDS, and XPS confirmed the successful loading and oxidation states of Ag and Au nanoparticles. Electrochemical characterizations revealed significantly enhanced photocatalytic activities for HTMs and their Janus-like composites, outperforming the performance of commercial P25 photocatalyst. Notably, Janus-like Ag-5/HTMs and Au-10/HTMs exhibited photocatalytic activities that were 90-fold and 60-fold higher than P25, respectively. Under irradiation, Janus-like Ag-5/HTMs achieved the highest degradation efficiency, mediated by reactive species (·OH, O₂^–·, ¹O₂, and h⁺) under ambient conditions. To further demonstrate its practical application, a device was fabricated by spin-coating Ag-5/HTMs onto spherical activated carbon. When applied to swimming pool water containing 98.20 MP/L of microplastics, achieving a high removal efficiency for microplastics. This study underscores the potential of Janus-like M/HTMs systems for the efficient and sustainable degradation of microplastics, advancing their application in environmental remediation.","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"26 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid exhibited significantly higher catalytic activity than the precursor in the C(sp³)–H bonds oxidation via switching the reaction path of HAT (hydrogen atom transfer) for the Ni₂Mg₂Mn-LDH to PCET (proton-coupled electron transfer) process. The turnover frequency (TOF) value significantly boosted from 27 h⁻¹ for Ni₂Mg₂Mn-LDH to 882 h⁻¹ for the hybrid material in the aerobic oxidation of benzyl methyl ether, which exceeds most reported catalysts. The characterization suggested that metal cations in hybrid coordinated with carboxylic acid in a monodentate manner, which would elevate the positive charge of Mn³⁺ species and the surface basicity probably related to M–O^2– structure. These improved properties facilitated the electron transfer and the proton transfer during the PCET process, respectively, and were responsible for the boosting catalytic performance for the hybrid in the aerobic oxidation of C(sp³)–H bonds.

Although efforts have been made to rejuvenate the spent catalysts, the recovery of these well-defined active sites is still a daunting challenge. In this work, silica supported palladium-phosphide nanoparticles, with uniform particle sizes (∼2.5 nm) and specific crystal structures were prepared and systematically characterized. The combined structure analysis reveals that the exposed Pd site changes from metal Pd surface to few-atom Pd ensembles and fully isolated Pd atoms with gradually increasing P content. For identical reaction conditions of propane dehydrogenation, both the clustered Pd atoms and isolated Pd^δ+ atoms exhibited dehydrogenation rates that is >10 times higher than the corresponding rate over Pd nanoparticle. Kinetic measurements demonstrated that the clustered Pd atoms on the surface of Pd₃P nanoparticle shows the highest activity for C–H activation, while its also favored by coke deposition, leading to a trade-off relationship between activity and stability. By contrast, PdP₂ nanoparticles exhibited a compromised dehydrogenation performance. Based on the deactivation mechanism of Pd-phosphide catalyst during dehydrogenation/regeneration cycles, an effective regeneration method, washing catalyst bed with alkaline-ethanol under mild conditions, was developed to remove deposited coke around dehydrogenation sites without sintering of nanoparticles. The structure–activity/stability relationship insights and facile regeneration method for the binary catalysts in this work offer improved knowledge of propane dehydrogenation catalyst.","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"68 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two ZEO-1 samples—phosphorus-containing and phosphorus-free—were evaluated to determine the influence of residual phosphorus species, originating from template decomposition, on acidity and catalytic behavior. Phosphorus-containing ZEO-1 exhibited a significantly lower concentration and strength of Brønsted acid sites, which led to reduced catalytic activity but improved stability, owing to limited coke formation and retention. In contrast, phosphorus-free ZEO-1 displayed higher activity, with coke deposits mainly composed of alkyl-naphthalene derivatives forming within the 12-membered ring channels. In this sample, coke led to deactivation via site poisoning, with one coke molecule deactivating one Brønsted acid site. Although the overall amount of coke formed on ZEO-1 was higher than on USY, the impact on catalytic performance was less severe. In USY, each coke molecule deactivated approximately three Brønsted acid sites, indicating higher coke toxicity. These results demonstrate that ZEO-1’s open microporous structure contributes to improved resistance to deactivation by coke, highlighting its potential as a stable catalyst for acid-catalyzed reactions.","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"12 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretical calculations further support this observation, showing that excitation wavelength influences charge distribution within the PCN framework.

Theoretical calculations reveal that the regioselectivity is primarily determined by the olefin insertion step. Xantphos ligand reduces the electron density of the Rh center and provides a sterically favorable environment for the linear pathway. Additionally, the acetoxy group in allyl acetate exerts a repulsive interaction with the Rh-carbonyl, directing Rh to preferentially coordinate with the β-C, thereby significantly enhancing the formation of 4-acetoxybutyraldehyde. In contrast, the PPh₃-modified Rh catalyst exhibits lower steric hindrance along the branched pathway, thus favoring the formation of branched aldehydes. Experimental investigations demonstrate that hydrogenolysis of allyl acetate predominantly occurs at the uncoordinated Rh sites, and the elevated H₂ concentration and higher temperature will promote this side reaction. For Xantphos, MKM simulations indicate that the increased pressure and optimized syngas composition (CO/H₂ = 0.5–2) can lead to linear aldehyde selectivity exceeding 98 %. Similarly, in the PPh₃ system, high pressure and a near-equimolar syngas ratio favor the formation of branched aldehyde. These findings unveil the intrinsic relationships between ligand design, reaction conditions and selectivity, establishing a structure–activity framework for hydroformylation of acetoxy-functionalized olefins.
