Оптимизация условий синтеза Ce1-xMxOy и Ni/Ce1-xMxOy (M = Gd, La, Mg) наноматериалов для водородной энергетики

Abstract

Nanomaterials Ce1-xMxOy and Ni/Ce1-xMxOy (M = Gd, La, Mg, x = 0-0,5) were prepared at variation of temperature, medium and duration of thermal treatment. The effects of type (M = Gd, La, Mg) and content (x = 0-0,5) of doping cation (M) on crystal structure and sintering of nanomaterials during calcination were investigated. It was shown that phase composition of materials did not change under rising of calcination temperature up to 800oC. The material stability against the sintering during thermal treatment increases at an increase of La or Mg content in the materials. The comparative study of functional properties of Ni/Ce1-xMxOy materials was carried out in autothermal reforming of ethanol (ATR of C2H5OH). It is demonstrated that Ni/Ce1-xMxOy samples provide high hydrogen yield in ATR of C2H5OH, which indicates their perspective application for hydrogen power engineering.
