Scholarcy highlights

  • Biomass polysaccharides are natural biopolymers and are considered as energy storage structural materials and suppliers in animals and plants
  • Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 across all institutions and individuals
  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • Chitin is the second most important biomass resource, which can be regarded as an alternative raw material for fine chemicals, especially in its homogeneous solution
  • A homogeneous aqueous solution of potassium hydroxide/urea was used as the solvent to dissolve chitin at first under a low-temperature pretreatment, which was degraded by a hydrothermal process
  • Up to 6% carbon dots can be obtained, which showed excellent fluorescent properties and promising applications in the detection of iron ions
  • This work provides an overview of the homogeneous conversion of chitin into an aqueous solution, from which both CDs and organic compounds can be obtained in a simple and green method
  • Such files may be downloaded by article for research use
