  15. Effect of transition metal element addition upon liquid phase reforming of methanol with water over TiO2 supported Pt catalysts

  16. The Ir catalyst for reforming

  17. Nano-spot EDS measurements revealed that the atomic ratio of Re/Ir is higher inthe elliptical particles than the spherical one. For the 5wt% Ir–Re(1:1)/SiO2 sample, the ratio of Ir/Re in a elliptical particle is 0.85,although the ratio is 0.40 in a spherical particle. This result confirms that the elliptical particles are composed of Ir–Re composite.

  18. Effect of the supporters The basic oxide supports improved the selectivity to CO2, whereas the acidic supports suppressed the catalytic activity and selectivity. highest rate of H2 formation; high selectivity to CO2 Catalytic activity of various supported Ir–Re catalysts for liquid phase methanol reforming with water
