摘要
Zeolitic imidazolate frameworks (ZIFs) were gradually used for oxygen evolution reactions (OER). Where the classical ZIF-67 was successfully obtained by gas-solid phase two phase flow synthesis method (GSF). Kinetic analysis of the reaction mechanism was carried out by detecting the P-XRD pattern of products with different reaction times. The single crystal ZIF-67 prepared with multiple active sites current density of 10 mA·cm−2 at 239 mV for the OER in 1 mol/L KOH solution. Finally, combined with density functional theory calculations, the post-formed Co centers during the OER process are believed to be responsible for the high OER activity. This study provides a new idea involving the bulk preparation of highly active center electrocatalysts using novel GSF reactions.
