Title:
PREPARATION METHOD AND DEVICE FOR METAL OXIDE SUPPORTED IRIDIUM/RUTHENIUM-BASED CATALYST
Document Type and Number:
WIPO Patent Application WO/2022/188278
Kind Code:
A1
Abstract:
The present disclosure provides a preparation method and device for a metal oxide supported iridium/ruthenium-based catalyst, comprising: S1. dispersing metal oxide in hydrochloric acid, carrying out heating treatment in an inert atmosphere, and washing and drying to obtain a precursor; S2. dispersing the precursor and a dispersing agent in an organic solvent to obtain a suspension; S3. adding an iridium salt/ruthenium salt into the suspension, and carrying out a constant-temperature reflux reaction to obtain the metal oxide supported iridium/ruthenium-based catalyst. The preparation method is simple, economical and environment-friendly, and is suitable for industrial large-scale production. Moreover, the prepared catalyst is a corrosion-resistant non-noble metal oxide supported catalyst, noble metal particles are small in particle size, low in loading capacity and high in dispersity, and the catalytic activity is high.
