Effects of A-site non-stoichiometry in YxInO3+δ on the catalytic performance during methane combustion.

A novel non-stoichiometric YxInO3+δ (YIO-x, 0.8 ≤ x ≤ 1.04) perovskite catalyst with a large number of oxygen vacancies and high specific surface area was synthesized using glycine self-propagating gel combustion. It was found that low levels of non-stoichiometry in the A site of YxInO3+δ effectively increased the amount of oxygen desorption by 39-42% when… CONTINUE READING
