Novel Pd-loaded self-standing hierarchical pore structure silicalite for low temperature toluene catalytic combustion

Abstract A novel Pd-loaded self-standing hierarchical pore structure silicalite were obtained by a handy polymer form board assisted hydrothermal method. The selected foam-shaped of polyurethane (PU) foam monolith was regarded as the precursor silicalite. fruiting can steadily hold unique macroporous network and shape anterior original PU . By means BET BJH size distribution tests, as-synthesis demonstrated structure. method in-situ reduction wielded to load palladium on silicalite, catalytic performance catalyst decompose toluene tested at multiple burning temperatures. experimental results revealed that effectively nearly 230°C, realizing low-temperature combustion toluene.
