Among potential feedstocks, 2,5-furan dicarboxylic acid (FDCA) stands out for its potential to be converted to higher-value polymeric materials such as polyethylene furandicarboxylate (PEF), a bio-based plastic alternative. In this study, the sustainable, electrocatalytic oxidation of stable furan molecule 2,5-bis(hydroxymethyl)furan (BHMF) to FDCA is investigated using a variety of TEMPO derivative electrocatalysts in a mediated electrosynthetic reaction.

It is also an important raw material for producing lithium-ion battery adhesives. The industrial method for producing dichloroethylene involves a saponification reaction between trichloroethane and sodium hydroxide, which can lead to high environmental pollution. The 1,1,2-TCE (1,1,2-trichloroethane) catalytic cracking method has been widely studied due to its environmentally friendly potential to replace the saponification method. However, the low performance and stability of the catalysts have hindered the further development. The main reason is the lack of research on the intermediate processes of catalytic cracking. In this paper, in situ FTIR (Fourier transform infrared spectroscopy) and mass spectrometry combined technology was innovatively adopted to study the intermediate process of catalytic cracking of 1,1,2-TCE. In situ FTIR was used to analyze the generation of intermediate products, and online mass spectrometry was used to analyze the composition of exhaust gas. The formation of saturated steam from inert gas bubbling reactants in an in situ reaction pool could be used to investigate the microscopic reaction behavior of reactants on the catalyst surface in a macroscopic time system. The results indicated that 1,1,2-TCE produced residual products such as chloroacetylene and vinyl chloride during the dehydrochloride process. When 0.6 Cs/Al<sub>2</sub>O<sub>3</sub> (activated alumina loaded with cesium chloride) was used as the catalyst, the dehydrochlorination of 1,1,2-TCE produced more chloroacetylene, reaching 4.62% at 533 K. When 0.6 Ba/Al<sub>2</sub>O<sub>3</sub> (activated alumina loaded with barium chloride) was used as the catalyst, the dehydrochlorination of 1,1,2-TCE produced more vinyl chloride, reaching 6.54% at 533 K. Under the catalysis of 0.6 Cs/Al<sub>2</sub>O<sub>3</sub>, the initial cracking temperature of 1,1,2-TCE was 405 K, while under the catalysis of 0.6 Ba/Al<sub>2</sub>O<sub>3</sub>, the initial cracking temperature of 1,1,2-TCE was 450 K.

The incorporation of ionic groups within these nanoconfined channels imparts the membrane with exceptional charge screening capabilities. Moreover, the membrane exhibits photoelectric responsivity, enhancing the ion conductivity upon exposure to light. As a result, this leads to a substantial increase in the output power density. In practical terms, when subjected to a salinity gradient of 0.5/0.01 M NaCl and exposed to light, the device achieved an outstanding peak power density of 18.0 ± 0.9 W m<sup>–2</sup>, surpassing the commercial benchmark by 3.6-fold. This innovative membrane design not only represents a significant leap forward in materials science but also opens promising avenues for advancing sustainable energy technologies.</p>","PeriodicalId":100230,"journal":{"name":"Chem & Bio Engineering","volume":"1 5","pages":"461–468"},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/cbe.3c00119","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140999250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
