“…These oxidation reactions can be induced by increased temperatures, higher pH, light, and presence of oxygen or various metals ions that have suitable redox potentials [13]. (5) In the literature, it is possible to fi nd examples of the use of ascorbic acid as a carbon source, e.g. in synthesis of Li 3 V 2 (PO 4 ) 3 /C [14] and Li 2 FeSiO 4 /C [15] as cathode materials for lithium ion batteries or for the synthesis of carbon coated PbTe [16] and CdTe [17] nanowires.…”

The studies of the synthesis of uranium carbide from uranyl-ascorbate gels using the complex sol-gel process (CSGP) have been carried out. The synthesis of uranyl-ascorbate mixture as liquid sol from uranium trioxide and ascorbic acid and solid gel by extraction of water from sol were carefully examined. Ascorbic acid was used as a complexing agent in complex sol-gel process and as a carbon source. The crucial step to obtain final uranium carbides from the aforementioned substrates is the carbonization process. The thermal behavior of ascorbic acid and uranyl-ascorbate gels in a nitrogen atmosphere in the temperature range of 25-900°C were investigated using TG-DTG. Furthermore, the products of the carbonization of uranyl-ascorbate gels in nitrogen, argon and vacuum atmosphere were identified by X-ray diffraction. TG-DTG was used also as a method for determining of carbon residues in the samples.
