Abstract

Ni–La/SiO2 catalysts were prepared by using a new metal organic precursor M(OC3H7)n, dissolved in organic solvent, hydrolysed and finally condensed to form inorganic polymers containing M–O–M or M–(µOH)–M linkages. An optimal distribution of both the active phase ‘Ni’ and the promoter ‘La2O3’ was ensured by addition of their corresponding salts, previously dissolved in propionic acid, to a silica solution prior to gelation. After drying under vacuum the precursor was submitted to thermal treatment in air at 600°C with a heating rate of 1°C min–1.

The precursors and the corresponding catalysts were characterised by various techniques (TG-DTA, XRD, FTIR, TEM, BET and porosimetry) and tested for methane dry reforming.
