Self-supported ZSM-5 zeolite monolith foams (ZMFs) with different Si/Al ratios have been successfully prepared by hydrothermal synthesis with a polyurethane foam (PUF) template followed by calcination in air at 550 °C to harden. Cu or Mn have been introduced on preformed ZMF samples to obtain monolithic catalysts that have been fully characterized by morphological (XRD and SEM), textural (BET and pore size distribution), mechanical (compressive strength) and chemical (ICP-MS) analyses, and eventually tested in the Selective Catalytic Reduction of NO with NH₃ in the temperature range 100–450 °C. The zeolite monolith foams are characterized by a well crystallized ZSM-5 structure, a BET surface area ca. 420 m² g⁻¹ and remarkable mechanical resistance even without any binder. Those structured catalysts show specific catalytic activity in line with powdered counterparts, but they can guarantee improved NO conversion due to the higher amount of catalyst per unit volume of reactor and to their superior mass transfer coefficients coupled to low internal diffusion limitations.

通过使用聚氨酯泡沫（PUF）模板进行水热合成，然后在550°C的空气中煅烧以硬化，已成功制备了具有不同Si / Al比的自支撑ZSM-5沸石整料泡沫（ZMF）。已将Cu或Mn引入预制的ZMF样品中，以获得整体催化剂，这些催化剂已通过形态学（XRD和SEM），质地（BET和孔径分布），机械（抗压强度）和化学（ICP-MS）分析进行了全面表征，并最终在100–450°C的温度范围内用NH ₃选择性催化还原NO进行了测试。沸石整料泡沫的特征在于良好结晶的ZSM-5结构，BET表面积约为2。420 m ² 克^-1甚至没有任何粘合剂也具有出色的机械强度。这些结构化催化剂显示出与粉末状对应物一致的特定催化活性，但是由于每单位体积反应器中催化剂量的增加以及它们优异的传质系数和较低的内部扩散限制，它们可以保证改善的NO转化率。
