Mg/Fe-LDH modified with <i>Moringa</i> biochar was created using in situ co-precipitation method. The synthetic LDHs were characterized using thermogravimetric analysis (TGA), field emission scan electron microscope (FE-SEM), transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS), X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET) techniques for nitrogen adsorption–desorption. Experimental design techniques are employed to optimize removal efficiency by examining factors such as pH, temperature, adsorbent dosage, and contact time. The resulting LDHs exhibits improved adsorption properties due to the combined effects of Mg/Fe LDHs and the high surface area of <i>Moringa</i> biochar (S_BET increased from 87 to 144 m²/g after modification with biochar). Through response surface methodology, optimal conditions are determined to maximize NG removal and found to be pH 7.8, contact time 150 min, dose 380 mg, and temperature 25°C. With an R² value of 0.999, 0.998 and an adjusted R² value of 0.997 and 0.993 in the RSM model for Mg/Fe and Mg/Fe-BC LDH, respectively, it can be concluded that the chosen model is appropriate for data analysis (quadratic model). Additionally, the adequacy precision was assessed using the signal-to-noise ratio, which was determined to be around 23 and 66 for Mg/Fe and Mg/Fe-BC LDH, respectively (significantly higher than the baseline of 4), indicating a satisfactory signal. The highest adsorption capacity of Mg/Fe and Mg/Fe-BC LDHs was determined to be 43 and 53 mg.g⁻¹ (with removal efficiencies of 82 and 97%, respectively). The Freundlich adsorption isotherm model testing characterized the removal of NG. A comprehensive kinetic study reveals a pseudo-first order. This study finds out the potential of Moringa biochar-modified Mg/Fe LDHs nanosheets as an effective green adsorbent for naphthol green removal in comparison with Mg/Fe free of biochar.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":509,"journal":{"name":"Catalysis Surveys from Asia","volume":"28 4","pages":"405 - 424"},"PeriodicalIF":2.1,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512667","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 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}
