Enhance catalytic activity.

Reduction of oxygen on the catalyst reactivity can increase the production of hydrogen from methane oxidation, Chinese scientists claim.

Partial oxidation of methane to produce syngas (a combination CO/H2) and is an attractive alternative to fossil fuels. However, this process appears simultaneously with the total methane oxidation does not produce H2 directly and also release heat to form hot-spots in the catalyst is not active or destroy them, obviously Guanzhong Lu in East China University of Science and Technology, Shanghai, China .

Lu and his colleagues found that the reactivity of atoms - atoms of oxygen on the catalyst to determine whether total or partial oxidation are going. Additions ion - europium ions into the catalyst structure to make a strong bond that prevents ato - oxygen atoms react and more hydrogen is produced.

A strong bond of metal - oxygen generated from direct hydrogen production.
'We're amazed to findings which hydrogen can be produced directly during the catalyst-doped europium oxide,' said Lu. 'This will engarahkan at a better use of methane; lower natural gas costs, which can reduce our dependence on fossil fuels,' he added.

Stuart Taylor, a expert on heterogeneous catalysts for selective oxidation at Cardiff University, commented that the 'Formation of hydrogen directly from the partial oxidation of methane is very desirable, but to achieve high results, the less stable products of oxidation of thermodynamics should be more controlled. "
