A non-solvent synthesis of alkali metal-doped [email protected] is presented that needs no mechanical grinding and utilizes heat treatment under an N2 gas flow. Pluronic® F127 is used to generate pores and a high surface area, and tannic acid is used as a carbon source for the [email protected] nanocatalysts. Because some C is transferred to organic compounds during the nitrogen heat treatment, this demonstrated the advantage of raising the weight ratio of active metals comparatively. The [email protected] nanocatalyst developed in this study outperformed commercial Pd/C catalysts by bimetallic PdCu-Pd-Cu nanoparticles and Pd nanoparticles in terms of catalytic activity (selectivity of commercial Pd/C: 45%; [email protected] nanocatalyst: 76%). The alkali metal dopants increase the selectivity of the final product on the [email protected] surface because they are electron-rich, which assists in the adsorption of the substrate (selectivity of [email protected] nanocatalyst: 76%; K-doped [email protected] nanocatalysts: 90%). Furthermore, even after being reused 5 times in this research, the final catalytic performance was comparable to that of the initial catalyst. View Full-Text
