We report on the simple preparation method of large-scale structured catalysts by temperature-regulated chemical vapor deposition with a high cell-density ceramic honeycomb monolith. And the feasibility for dry reforming of methane catalysts was evaluated. The NiO/Cordierite (CDR) catalyst was prepared by controlling coating conditions at each temperature step, leading to a conformal deposition of NiO inside the cordierite honeycomb monolith with the cell density of 600 cpsi. The catalytic conversion of $CH_4$ and $CO_2$ for dry reforming of methane were about 83% and 90% with gas hourly space velocity of $10,000h^{-1}$ at $800^{\circ}C$, respectively. As a result, it exhibited that the temperature-regulated chemical vapor deposition method can be expedient for the preparation of large-scale structured catalysts.
