Synthesis of titanium nitride via hybrid nanocomposites based on mesoporous TiO2/acrylonitrile

Abstract In the present study, the synthesis of titanium nitride (TiN) by carbothermal reduction nitridation (CRN) reaction using nanocomposites made of mesoporous TiO2/acrylonitrile with different content of inorganic phase were explored. The choice of hybrid nanocomposite as precursor for the synt...
