The invention belongs to the technical field of the resource treatment of industrial wastes, and particularly relates to a method for preparing a cementing material using smelting industrial waste slag after utilizing the simultaneous removal of SOand NOin flue gas and an application of the cementing material obtained by the same. According to the invention, SOand NOin the flue gas can be treated with the smelting industrial waste slag, meeting requirement of flue gas desulfurization and denitration; moreover, the smelting industrial waste slag can be purified and separated by means of waste gas resources to obtain a cementing material, realizing the resource utilization of the smelting industrial waste slag and waste gas.

The present invention discloses a preparation method of a catalyst with white carbon black modified by Zr&#x2014;Nd&#x2014;O and use thereof, and belongs to the field of catalyst technologies. In the present invention, an organic solvent evaporation induced self-assembly method is used to load Zr&#x2014;Nd&#x2014;O onto white carbon black to obtain a mesoporous Zr&#x2014;Nd&#x2014;O/white carbon black catalyst. The mesoporous Zr&#x2014;Nd&#x2014;O/white carbon black catalyst in the present invention has high catalytic activity, contains uniformly distributed mesopores with a relatively large average aperture, and has a simple preparation process, etc.
