Synthetic Strategies of Supported Pd-Based Bimetallic Catalysts for Selective Semi-Hydrogenation of Acetylene: A Review and Perspectives

“…For the fabrication of high-performance Pd-based bimetallic catalysts, it is necessary to design suitable preparation methods based on the understanding of various preparation strategies. Recently, there are some excellent reviews that summarize the preparation methods of the supported Pd-based bimetallic nano-catalysts [ 10 , 38 , 54 , 55 , 62 , 68 , 69 ]. However, some new synthetic technologies and new catalysts have not yet been classified because they have just been reported.…”

“…The IWI method is a high-productivity, cost-effective, and straightforward approach that is widely used in the preparation of industrial Pd-based bimetallic catalysts for bulk chemicals, fine chemicals, and petrochemical products [ 68 , 69 ]. Depending on the impregnation sequence of two metal precursor solutions, (IWI) these methods are divided into two types: sequential incipient wetness impregnation (Seq-IWI) and incipient wetness co-impregnation (Co-IWI).…”

“…The precipitation method is the other most efficient and simplest way of synthesizing supported Pd-based bimetallic catalysts [ 59 , 68 , 69 , 73 ]. Depending on the forms of support precursors (solid substrate or metal cation) introduced into the precipitation system, the precipitation method is divided into deposition–precipitation (DP) and co-precipitation (CP).…”

“…Depending on the forms of support precursors (solid substrate or metal cation) introduced into the precipitation system, the precipitation method is divided into deposition–precipitation (DP) and co-precipitation (CP). Similar to the IWI method, the DP method typically consists of four steps: metal precursor loading on support, drying, calcination, and thermal reduction [ 68 , 69 ]. Nevertheless, the metal precursor loading on support for DP is carried out in the liquid phase.…”

Noble metal nanodendrites: growth mechanisms, synthesis strategies and applications

“…[12][13][14][15][16][17][18][19] The physical and chemical properties of noble metal nanocrystals can be extensively tailored by adjusting their size and shape. 20 Some nanocatalysts with different morphologies (e.g., cubes and octahedrons) can expose different crystal facets, which bring about different atomic arrangements on the surface and directly affect the adsorption energy of intermediates in catalytic reactions. [21][22][23] In addition, the ultrathin and porous structures usually boost the electron/mass transfer ability and thus the activity.…”
