Layered porous SiO2 (V-SiO2) was designed and prepared from vermiculite by expansion-acidification method, and then used as a catalyst support to prepare Ni/V-SiO2 for dry reforming of methane. It is well known that sintering and carbon deposition of metal particles are two main problems in deactivation of nickel-based catalysts for methane dry reforming. It is reported that strong metal support interaction is a possible solution. Here, a Ni/V-SiO2-H catalyst derived from Ni-phyllosilicate was developed, and compared with the catalyst Ni/V-SiO2-IM by impregnation method. The results showed that the Ni/V-SiO2-H catalyst had high catalytic activity and stability, and the CH4 conversion reached 71.7% at 700 �C. The reason is that on the one hand, the active metal particles in the catalyst are small (8.3 nm) and relatively evenly dispersed; on the other hand, the catalyst has strong metal support interaction, which improves the anti sintering ability of the catalyst and affects the catalytic activity. It is considered that V-SiO2 as a catalyst support for the preparation of Ni-phyllosilicate may have wide application.

AbstractExploring a simple, fast, solvent-free synthetic method for large-scale preparation of cheap, highly active electrocatalysts for industrial hydrogen evolution reaction is one of the most promising work today. In this work, a simple, fast and solvent-free microwave pyrolysis method is used to synthesize ultra-small (3.5 nm) Ru-Mo2C@CNT catalyst with heterogeneous structure and strong metal-support interaction in one step. The Ru-Mo2C@CNT catalyst only exhibits an overpotential of 15 mV at a current density of 10 mA cm−2, and exhibits a large turnover frequency value up to 21.9 s−1 under an overpotential of 100 mV in 1.0 M KOH. In addition, this catalyst can reach high current densities of 500 mA cm−2 and 1000 mA cm−2 at low overpotentials of 56 mV and 78 mV respectively, and it displays high stability of 1000 h. This work provides a feasible way for the reasonable design of other large-scale production catalysts.
