摘要: Black wattle tannin (BWT), a typical natural plant polyphenol, was used as amphiphilic stabilizer to prepare BWT-stabilized Pd nanoparticles (BWT-Pd) catalyst. The as-prepared catalyst found be highly active in aqueous–organic biphasic hydrogenation of quinoline, which exhibited 100% selectivity 1,2,3,4-tetrahydroquinoline (py-THQ). Furthermore, the BWT-Pd can reused 3 times without significant loss catalytic activity, thus providing an effective and environmentally benign strategy for production py-THQ.
