열화학싸이클 수소를 제조를 위한 (Cu0.5Mn0.5)Fe2O4의 열적 거동

Abstract

Thermal behaviors of (Cu0.5Mn0.5)Fe2O4, prepared by a solid method, were investigated for H2 production by a thermochemical cycle. The thermal reduction of (Cu0.5Mn0.5)Fe2O4 started from 300 ℃ and the weight loss was 1.3 wt% up to 1200. XRD shows the prepared ferrite has the spinel structure with a lattice constant of 8.414Å and changed to the oxygen deficient structure by thermal reduction. Oxygen and hydrogen can be separately produced by the cycles of thermal reduction and water oxidation of the oxygen deficient ferrite.
