Abstract: The present invention relates to a monolith catalyst for carbon-dioxide/methane reforming and a method of manufacturing the same, and more particularly to a novel monolith catalyst for a reforming reaction having improved thermal durability, configured such that a sintering inhibiting layer is formed by coating the surface of a monolith support with at least one element selected from the group consisting of Group 2, 3, 6, 13, 15 and 16 elements among elements in Period 3 or higher and an active catalyst layer is formed on the sintering inhibiting layer, thereby preventing carbon deposition and catalyst deactivation due to deterioration even upon reaction at high temperatures.

Abstract: The present invention relates to a kit for concentrating low-concentration air pollutants, and to a concentration kit for concentrating low-concentration air pollutants, and then desorbing same so as to detect the components and concentrations of the pollutants. The present invention comprises: a sensor positioned on a channel in which gas moves, so as to detect pollutants in the gas; and a concentration part, which comprises an adsorbent for adsorbing and desorbing the pollutants in the gas moving to the sensor, so as to transfer concentrated pollutants to the sensor.
