Such catalysts may contain Pd nanoparticles on jute plant sticks (GS), i.e., Pd@GS, and may be formed by reducing, e.g., K2PdCl4 with NaBH4 in water, and then used this as a “dip catalyst.” The dip catalyst can catalyze Suzuki-Miyaura and Mizoroki-Heck cross coupling-reactions in water. The catalysts may have a homogeneous distribution of Pd nanoparticles with average dimensions, e.g., within a range of 7 to 10 nm on the solid support. Suzuki-Miyaura cross-coupling reactions may achieve conversions of, e.g., 97% with TOFs around 4692 h?1, Mizoroki-Heck reactions with conversions of, e.g., a 98% and TOFs of 237 h?1, while the same catalyst sample may be used for 7 consecutive cycles, i.e., without addition of any fresh catalyst.

The number of the communicating pores is at a density of not less than 18000 [pores/0.25 mm2] before a catalyst is supported in the pores. An exhaust gas purification filter having the honeycomb structure body with the catalyst is arranged in an exhaust gas pipe to purify exhaust gas containing PM emitted from an engine.
