摘要：

Activated carbon was prepared from peach stones and used as a host matrix of nanosized MFe2O4 (M = Cu, Zn, Mn) spinel ferrites. The obtained composites were characterized by Nitrogen physisorption, XRD, UV-Vis, FTIR, Moessbauer spectroscopy and TPR with hydrogen. Their catalytic behaviour was tested in methanol decomposition with a potential application as hydrogen carrier. Activated carbon based catalysts revealed higher catalytic activity but relatively low selectivity to syngas formation than their analogues hosted in mesoporous silica matrix. ZnFe2O4 is more appropriate active phase for the activated carbon support, while CuFe2O4 has higher activity on the silica matrix. The role of different supports on the state of catalytic active phase was discussed in detail.
