The properties of nickel nanoparticles inside the mesopores of SBA-15 support were tuned by a careful control of the calcination rate. Ni/SBA-15 catalysts containing 5 wt% nickel were prepared following three different calcination rate values (0.25 −0.5 −4.5 °C min−1). Their properties were characterized by N2-sorption, X-ray diffraction (low and wide angles), temperature programed reduction and transmission electron microscopy. These catalysts were then tested in dry reforming of methane (DRM). As a result, the catalyst calcined at 0.5 °C min−1 resulted in the formation of strong interaction between the active phase and the SBA-15 support, high nickel dispersion and accessibility that greatly enhanced its stability in dry reforming of methane.
