Article
Restricted access - publisher's policyCopper ion substituted MAl2O4 (M = Mg, Mn, Fe, Ni and Zn) spinels, CuxM1-xAl2O4 (x = 0.03 and 0.05), have been synthesized by a single step solution combustion method. Of the various compositions studied the 3 at.% copper ... -
High activity in the dry reforming of methane using a thermally switchable double perovskite and in situ generated molecular level nanocomposite
(Royal Society of Chemistry (RSC), 2024-01-01)
Article
Restricted access - publisher's policyThis work emphasizes the dry reforming of methane (DRM) reaction on citrate sol–gel-synthesized double perovskite oxides. Phase pure La2NiMnO6 shows very impressive DRM activity with H2/CO = 0.9, hence revealing a high ... -
