Influence of Ca/P ratio on the catalytic performance of Ni/hydroxyapatite samples in dry reforming of methane

摘要

A series of Ni/hydroxyapatite samples presenting different Ca/P molar ratios were synthesised to study the influence of the hydroxyapatite support composition on their catalytic properties in the dry reforming of methane. Our results reveal that a preparation starting from a sub-stoichiometric composition (Ca/P < 1.67) followed by the impregnation of Ni results in suitable properties which give the highest catalytic performance compared with stoichiometric (Ca/P = 1.67) and over-stoichiometric (Ca/P = 1.73) compositions, respectively.
