High surface area mesoporous solid support has attracted much interest in the development of cost-effective catalysts for NO_x abatement at low temperatures. SBA-15, a high surface area mesoporous material, was employed in the preparation of Al, Ti, and Zr incorporated SBA-15 through a direct synthesis approach under long hydrothermal reaction conditions (100 °C for 72 h). Heteroatom incorporation facilitated change in the morphology and textural properties of the material and was applied as a catalytic supports in order to facilitate the development of a MnCu bimetallic catalyst by a facile conventional co-impregnation method. At temperatures as low as 260 °C, the catalyst that was developed displayed superior deNO_x activity for SCR of NO with NH₃. There have been various physicochemical studies undertaken on the catalysts that were prepared, such as XRD, XPS, BET, HR-SEM, and HR-TEM. The deNO_x optimization and deNO_x activity over the catalysts are discussed. The exceptional deNO_x activity at low temperatures may be attributed to the rod-like morphology, extensive oxygen vacancies, and high ratio of Mn³⁺ + Mn⁴⁺/Mn on 10Mn4Cu/Zr-SBA-15 catalyst. Furthermore, the catalyst also displayed a synergetic interaction between the Mn and the Zr species on its surface, which contributed to the catalyst's superior catalytic recycle ability and its long-term stability on stream stability. A useful approach of preparation is provided in order to accomplish the industrial use of a bimetallic catalyst consisting of manganese and copper at a low cost.

高表面积介孔固体载体在开发用于低温下 NOx 减排_的具有成本效益的催化剂方面引起了很大兴趣。SBA-15 是一种高表面积介孔材料，在长水热反应条件下（100 °C，72 小时），通过直接合成方法制备掺入 Al、Ti 和 Zr 的 SBA-15。杂原子的掺入促进了材料形态和结构特性的变化，并被用作催化载体，以促进通过简便的常规共浸渍方法开发 MnCu 双金属催化剂。在低至 260 °C 的温度下，所开发的催化剂对使用 NH _{3的 NO SCR 表现出优异的脱硝活性}. 已经对制备的催化剂进行了各种物理化学研究，例如 XRD、XPS、BET、HR-SEM 和 HR-TEM。讨论了催化剂的脱硝_优化和脱_硝活性。低温下出色的脱硝_活性可能归因于棒状形态、广泛的氧空位和高比率的 Mn ³⁺ + Mn ⁴⁺/Mn 在 10Mn4Cu/Zr-SBA-15 催化剂上。此外，该催化剂还表现出其表面Mn和Zr物种之间的协同相互作用，这有助于催化剂优异的催化循环能力及其对流稳定性的长期稳定性。为以低成本实现锰铜双金属催化剂的工业化应用提供了一种有用的制备方法。
