Assignee: QATAR UNIVERSITY
Field: Chemical engineering (Chemistry)
Classification: CPC B  C | IPC B  C

Claim 17:
18. The method of claim 13, wherein the single-step solution combustion synthesis comprises the steps:
1) dissolving metal precursor nitrates in water and adding glycine to obtain a mixture wherein the nitrates are copper nitrate trihydrate (Cu(NO3)2·3H2O), zinc nitrate hexahydrate (Zn(NO3)2·6H2O), aluminum nitrate nonahydrate (Al(NO3)3·9H2O), and lanthanum nitrate hexahydrate (La(NO3)3·6H2O);
2) stirring the mixture to form a homogeneous mixture and heating the homogeneous mixture over a hot plate for combustion to obtain nanocomposites;
3) calcining the nanocomposites to remove uncombusted metal precursor nitrates in air in a muffle furnace to obtain the nanocomposite catalyst; and
4) activating/reducing the nanocomposite catalyst by passing pure hydrogen stream over the nanocomposite catalyst.
