Application

  • Light energy utilization and microbial catalysis for enhanced biohydrogen: Ternary coupling system of triethanolamine-mediated Fe@C-Rhodobacter sphaeroides: Triethanolamine is used to enhance light energy utilization and microbial catalysis in a novel ternary system, significantly boosting biohydrogen production efficiency (Jiang et al., 2024).

  • Purification and use of crude green glycerol from the transesterification of triglycerides in the formulation of an alcohol gel hand sanitizer: Triethanolamine is used to optimize the formulation of a novel alcohol gel hand sanitizer, enhancing its microbial effectiveness and user safety (Trindade Mazala et al., 2024).
