Abstract

Transition metal oxides (TMOs) are the most important catalysts in industrial chemistry. Tailoring the porosity of TMOs and the dispersion of active noble metal species are two strategies to enhance catalytic performance. However, the method of simultaneously producing porosity and high dispersion is quite scarce. Here, we propose a principle that NaCl-based solid solution could serve as a versatile platform to control both porosity and dispersion within TMO catalysts. The essence of this strategy lies in the ion-sharing talent of NaCl as a salt matrix by mechanochemistry, which promotes the high distribution of transition-metal precursors and noble metal species on NaCl crystalline. Besides, removing NaCl also releases pores. The corresponding TMO catalysts exhibit quite high catalytic performance in redox reaction.
