Application

  • Advancing mesoporous carbon synthesis for supercapacitors: Research highlights the use of glyoxylic acid as a cross-linking agent in the synthesis of mesoporous carbons, enhancing their functionality for supercapacitor applications. This study provides key insights into the design of advanced energy storage materials (Song et al., 2023).
  • Thermoset films and coatings: Glyoxylic acid is utilized to create ductile, high-lignin-content thermoset films and coatings, showcasing its applicability in sustainable material engineering. This approach offers new opportunities for the development of environmentally friendly coatings and films (Boarino et al., 2023).
  • Organic synthesis: A novel decarboxylative N-formylation of amines using glyoxylic acid, promoted by H2O2, has been documented, highlighting its role as a reagent in organic synthesis. This method represents a significant advancement in the synthesis of amine derivatives (Wu et al., 2023).
  • Enhancing luminescence in covalent organic frameworks: A study demonstrates the incorporation of glyoxylic acid as a linker in two-dimensional covalent organic frameworks, significantly boosting their luminescence. This finding opens up new avenues for the use of these materials in optoelectronic applications (Yang et al., 2023).
