Necessary of a SCR catalyst is on the rise because the regulations of atmospheric pollutants have been tightened in the field of stationary source such as a power plant due to flue gases containing the nitrogen oxide (NOx). Above all, low temperature catalyst is spotlighted due to space constraints and energy saving. However, catalytic active materials are easily aggregated at ambient continuous thermal environment with the operating temperature, and then the aggregated particles can lead the catalyst performance to degrade. Because hexagonal boron nitride (h-BN) is well known as thermally stable material and porous structure is attributed to high surface area, the catalytic active materials have the improved dispersion with nano-size by utilizing h-BN with porous structure. And in doing so, porous h-BN supported low temperature catalyst shows the high NOx abatement efficiency owing to the improved dispersion of the nanoparticles.
