Thread Content

The 25th National \"Safety Production Month\" in 2026: Everyone talks about safety, and everyone knows how to handle emergencies; identifying and addressing risks and hazards. -------------------------------------------------- Current hot topics in chemical engineering are concentrated in five areas: green and low-carbon development, energy transition, biomanufacturing, intelligent chemistry, and high-end materials, all in line with the goals of reducing carbon emissions and promoting industrial upgrading. I. Green, low-carbon, and carbon-neutral chemical industries Carbon dioxide capture, utilization, and storage (CCUS): Electrocatalytic/photocatalytic reduction of CO₂ to produce ethylene, ethanol, etc ； CO₂-coupled alkane conversion (such as CO₂-oxidized propane dehydrogenation).  Green hydrogen and hydrogen production from new energy sources: Hydrogen production via water electrolysis using renewable energy (PEM / alkaline electrolyzers) ； Hydrogen storage and transportation (liquid organic hydrogen carriers, high-pressure hydrogen storage) ； Green hydrogen coupled with coal chemical industry / synthetic ammonia.  Recycling of waste resources: Catalytic pyrolysis/depolymerization of waste plastics ； Recycling of used battery materials (lithium/cobalt/nickel) ； Synergistic value enhancement of industrial solid waste. II. New Energy and Electrochemical Engineering  New battery materials and devices: Solid-state batteries (sulfide/oxide electrolytes) ； High-nickel ternary/manganese-rich cathode, silicon-carbon anode ； Key materials for sodium-ion batteries.  Electrocatalysis and energy conversion: Hydrogen production by water electrolysis (HER/OER catalysts) ； Nitrogen reduction to ammonia (electrocatalysis / chemical chain) ； Fuel cell catalysts (Pt-based / non-precious metals).  Photovoltaic and energy storage materials: Perovskite solar cells ； Photothermal conversion materials ； Supercapacitor electrode design. III. Synthetic Biology and Biomanufacturing  Synthetic biology: gene editing (CRISPR), metabolic engineering of microorganisms ； Bio-based platform compounds (such as succinic acid, adipic acid) ； Microbial fermentation for the production of drugs/fragrances. Biopharmaceuticals and Vaccine Engineering: Preparation of mRNA vaccine lipid nanoparticles (LNP) ； Antibody-drug conjugate (ADC) process ； Cell culture and separation purification.  Enzyme engineering and biocatalysis: Design of immobilized enzymes ； Bionic catalysis ； Enzyme-coupled chemical catalysis (such as bio-chemical tandem reactions). IV. Intelligent Chemical Engineering and Process Intensification  AI + Chemical Engineering: Machine learning-assisted catalyst/molecule design ； AI-driven reaction pathway prediction and process optimization ； Digital twin factories and intelligent control.  Microchemical engineering and continuous flow technology: microchannel reactors (efficient heat and mass transfer, enhanced safety) ； Continuous flow chemistry as an alternative to batch processes ； Modular and automated production. External field enhancement and novel separation: supercritical fluid extraction ； Membrane separation (osmotic vaporization, gas separation) ； Microwave/ultrasound/light field synergistic reaction. V. Advanced Functional Materials Chemistry  Semiconductors and electronic chemicals: photoresists, high-purity reagents, electronic specialty gases ； Semiconductor packaging materials ； Preparation and applications of 2D materials (graphene, MXene).  High-performance polymers and composites: high-strength fibers (carbon fiber, aramid) ； Self-healing / smart responsive materials ； Biomedical materials (tissue engineering scaffolds, drug carriers).  Catalytic materials and nanotechnology: single-atom catalysts, core-shell structured nanocatalysts ； Confined space catalysis ； Applications of nanomaterials in environmental protection/energy. Summary of key trends  Greening: Shift from fossil fuels to CO₂, biomass, and waste as raw materials ； The process is low-carbon and waste-free.  Intelligence: AI is integrated throughout the entire process of design, synthesis, representation, and deployment, resulting in shortened development cycles and reduced costs.  Interdisciplinary integration: chemistry + biology, chemistry + materials, chemistry + energy, chemistry + data science – the boundaries between these fields continue to blur.
