ABSTRACT A modified sol–gel method using β‐cyclodextrin as a template was used to synthesize apatite‐type lanthanum and praseodymium silicate supports for Ni‐loaded ethanol steam reforming catalysts. The effects of nonionic Brij 58 surfactant addition and the substitution of lanthanum with praseodymium on the properties of catalysts were studied. Thermal decomposition of the sample precursor gels was investigated by thermal analysis coupled with evolved gas mass spectrometry. The samples were analyzed by XRD, EDX, low‐temperature nitrogen physisorption, temperature‐programmed reduction with H 2 , XPS, oxygen isotope exchange with C 18 O 2 , and tested in the ethanol steam reforming.
Lopatin et al. (Tue,) studied this question.
