摘      要：It is always highly pursued to develop efficient and durable catalysts for catalytic ***,intermetallic PdBi aerogels with tunable activity were prepared successfully via a surfactant-free spontaneous gelation *** prepared PdBi aerogels have a three-dimensional high porous structure and plentiful active sites pervaded on the ultrathin interlinked nanowires *** unique structures,as well as the synergistic effect between Pd and Bi,can accelerate mass and electron transfer,and improve the atom utilization ratio of Pd atoms to promote the catalytic *** a proofof-concept application,the optimized Pd_(2) Bi_(1) aerogels exhibit 4.2 and 6.2 times higher catalytic activity for the reduction of 4-nitrophenol(4-NP)and methylene blue(MB)than those of commercial Pd/C,*** the introduction of non-noble metal of Bi,the cost of the resulted Pd Bi aerogels can be dropped signi ficantly while the catalytic capability of Pd Bi aerogel will be improved *** strategy will bring good hints to rationally design fine catalysts for various applications.
