In this study, Ni_xMo_y@NC bimetallic catalysts with varying molar ratios were prepared using ZIF-8 as a representative MOF precursor. Lauric acid was chosen as the model compound, the catalytic performance of these catalysts with different metal ratios, reaction temperatures, and pressures was investigated. In addition, the reaction of lauric acid, lauric alcohol, and lauric aldehyde at different reaction times were investigated to explore the pathways of lauric acid. The influence of Mo doping on the catalyst structure, reducibility, and electronic properties was investigated through a series of characterizations, including SEM, TEM, XPS, H₂-TPR, and NH₃-TPD. This study revealed that the ZIF-8 support with incorporated Ni and Mo maintained a stable structure. Compared to Ni-based catalysts, the addition of Mo in the bimetallic catalyst can bring the electron transfer between Ni and Mo and increased the active sites and acid sites. An appropriate amount of Mo can lower the reduction temperature and enhance the catalytic activity for hydrogenation and deoxygenation reactions. Based on the catalytic experimental results, it can be observed that liquid alkanes, such as undecane and dodecane, are primarily formed through decarbonylation of lauric aldehyde and hydrodeoxygenation of lauric alcohol. Additionally, under high-temperature conditions, the hydrodeoxygenation reaction is favored over the decarbonylation reaction, promoting the production of dodecane. This indicates that Mo exhibits better activation for the C–OH reaction, leading to these observations. Under repeated use, the catalyst still has good catalytic activity and stability.</p></div>","PeriodicalId":509,"journal":{"name":"Catalysis Surveys from Asia","volume":"28 3","pages":"269 - 282"},"PeriodicalIF":2.1,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140799569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, we introduce a new electro-organic approach for the synthesis of methyl cinnamate derivatives through the Heck reaction, carried out under green conditions. The conventional Heck reaction, widely used for synthesizing diverse compounds, suffers from drawbacks like the use of toxic solvents, harsh reaction conditions, and the generation of waste. To address these challenges, we employed an electrochemical method, offering a more sustainable alternative. Our electro-organic process utilized a two-electrode setup with easily available anode and cathode materials. Through the application of an appropriate potential difference, both the aryl halide and olefin substrates were electrochemically activated, leading to the formation of the desired methyl cinnamate derivatives. This innovative approach offers several significant advantages. Firstly, it eliminates the need for toxic catalysts, reducing the environmental impact related to waste disposal. Secondly, the mild reaction conditions allow for the use of a broad range of functional groups, enabling the synthesis of diverse methyl cinnamate derivatives. Moreover, the electrochemical approach demonstrates exceptional selectivity and efficiency, resulting in high product yields. Additionally, the method is easily scalable, making it suitable for large-scale production. The affordability and accessibility of the electrode materials further contribute to the sustainability of the process. In summary, our electro-organic method represents a greener and more efficient strategy for synthesizing methyl cinnamate derivatives via the Heck reaction. It not only addresses the limitations of conventional methods but also aligns with the principles of sustainable chemistry. We expect this novel methodology to find widespread applications in the synthesis of various important compounds, promoting the development of more sustainable chemical processes.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":509,"journal":{"name":"Catalysis Surveys from Asia","volume":"28 2","pages":"200 - 208"},"PeriodicalIF":2.1,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139586684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
