However, they are easy to aggregate and difficult to dissolve, and their application in the field of photocatalysis is limited. Based on the above problems, in this study, three four-arms star-shaped thermosensitive copolymers (PcZn-(PNIPAM_n-co-PUMPP_m)₄) photocatalysts with zinc phthalocyanine as the core and porphyrin thermosensitive copolymer as the arms was constructed by using RAFT polymerization technology and the ’core first’ route. The visible light catalytic activity of the prepared star-shaped copolymers was evaluated by using 1,5-dihydroxynaphthalene (DHN) and methylene blue (MB) as model pollutants. The three copolymers were found to be effective in oxidizing DHN to juglone and degrading MB. Among them, PcZn-(PNIPAM_33.5-co-PUMPP_1.6)₄ (P3) showed the highest DHN conversion efficiency (100.0 %), reaction yield (70.0 %) and MB degradation (96.9 %). ¹O₂ and O₂·^- are the main active substances in the visible photocatalytic process. Based on UV–vis absorption spectra, Fluorescence spectra, EIS Nyquist plots and transient photocurrents, it is confirmed that P3 has a wider range of visible light absorption, and there is effective energy and electron transfer between TTPcZn and UMPP units in P3, which makes it have higher catalytic activity. More importantly, the lower critical solution temperature (32.6 ∼ 32.9 °C) of P3 makes it possible to achieve homogeneous catalysis and heterogeneous recovery through simple temperature regulation in the catalytic process, which makes P3 have good reusability. This work paves a way for the construction of high-performance and recyclable visible polymer photocatalyst.</div></div>","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"445 ","pages":"Article 116009"},"PeriodicalIF":6.5,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418465","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}

In this study, we develop a strategy to establish strong metal-support interactions, enabling Cu/NC (nitrogen-doped carbon) catalysts to efficiently produce value-added products under mild conditions. Specifically, we prepare a cost-effective NC support with highly dispersed ultrafine nano-Cu particles of approximately 1 nm in diameter. Under mild pH conditions, our comparative experiments show that the Faradaic efficiency for value-added products (furfuryl alcohol and 2-methylfuran) is nearly four times higher than that of commercial foam copper. We elucidate the influence of nitrogen-doped supports on the behavior of the supported metal Cu. Comprehensive in-situ infrared reflection absorption spectroscopy characterization and DFT theoretical calculations reveal a positive shift in the d-band center of the Cu 3d orbitals. This shift enhances the adsorption of furfural C1=O1 bonds on the Cu/NC catalyst and improves its capacity to bind active hydrogen, thereby increasing the Faradaic efficiency of the value-added products.

Three competing methanol formation mechanisms (the formate, carboxyl and CO hydrogenation pathways) are investigated; the least energy-demanding pathway followed the formate mechanism: CO₂* → HCOO* → H₂COO* → H₂COOH* → H₂CO* → H₃CO* → H₃COH. We report the coexistence of several formate adsorbates, some of which being highly stable spectators that were observed spectroscopically.

The methoxy intermediate is also highly stable, in agreement with its spectroscopic observation. The most energy-demanding elementary process is hydrogenation of methoxy to methanol (<em>E</em>_a = 1.20 eV).
