Method of preparing crystalline TiO2 nanoparticles on the surface of carbonaceous material derived from lignocellulosic biomass

• Summary:

  The invention relates to a low temperature method for the production of crystalline TiO2 nanoparticles on a surface of carbonaceous material derived from lignocellulosic biomass by means of an ultrasonic-assisted sol-gel method together with the addition of an acid from the hydroxy carboxylic acid group.

• Advantages / Innovative aspects:
  • simplicity of method and low cost of equipment,
  • great ability to modify some parameters (e.g. ultrasound intensity),
  • the ability to obtain crystalline TiO2 particles of reproducible size,
  • synthesis in a relatively short time and does not require the use of high temperature associated with material calcination
