What is the research gap of catalyst in biodiesel process?4 answersThe research gap in biodiesel catalysts lies in the need for more sustainable, efficient, and cost-effective catalyst materials to enhance the production process. Current catalysts face challenges such as sensitivity to impurities in low-quality oil feedstocks, leading to additional pre-treatment steps that increase costs and environmental impact. While solid catalysts show promise for green and economical biodiesel production, there is a focus on developing bifunctional solid acid/base catalysts to address the simultaneous esterification of free fatty acids and transesterification of triglycerides. Additionally, the exploration of novel homogeneous and heterogeneous catalysts, including ionic liquids and deep eutectic solvents, is crucial for achieving high purity and easy separation of biodiesel from glycerol. Future research directions aim to bridge these gaps by developing innovative catalysts for sustainable and efficient biodiesel production.
What are the latest advances in MOFs catalysis?4 answersMetal-organic frameworks (MOFs) have shown great potential in catalysis for CO2 conversion and solar-to-chemical energy conversion. Recent advances in MOF-based photocatalysts have focused on incorporating different functional ligands or metals into the parent MOFs to enhance their photocatalytic performance. Additionally, efforts have been made to modify MOFs-based photocatalysts for enhanced photocatalytic activities, such as coupling with inorganic semiconductors, carbon materials, and dye-photosensitizers. MOFs have also been explored as multifunctional electrocatalysts, particularly for trifunctional applications in regenerative fuel cells, zinc-air batteries, and overall water-splitting devices. However, the use of MOFs for trifunctional electrocatalytic applications is still in the budding phase and requires further exploration. Overall, the latest advances in MOFs catalysis involve their application in CO2 conversion, solar-to-chemical energy conversion, and multifunctional electrocatalysis, with a focus on enhancing their performance through functionalization and modification.

How to make carbide using MOF?5 answersA universal synthetic strategy for making carbide using MOF involves several steps. First, the dispersion of a three-dimensional MOF material in an organic solvent is obtained, followed by a solvothermal reaction to obtain a two-dimensional MOF material. This two-dimensional MOF material is then subjected to carbonization treatment to obtain the two-dimensional MOF derivative carbide. Another approach involves the in situ growth of MOFs on a three-dimensional substrate, such as nickel foam, followed by pyrolysis to obtain metal carbide nanoparticles encapsulated in carbon layers. Additionally, heterometallic oxides and/or carbides can be obtained by calcining a bimetallic metal-organic framework. These methods provide a way to synthesize carbides with controllable nanostructures and sufficient active sites for various applications, such as catalysis and electrochemistry.
