专利号:WO-2025098180-A1 优先权日:2023-11-10 标题:Cobalt-iridium nanocrystal and preparation method therefor, and water electrolysis catalyst 发明人:WANG YANFEI; WANG JINGJING; YU YINGLONG; HE SHENGBAO; SHAO CHENYI; LONG CHUAN; HE YEHENG; LI QINGXUN; ZHAO QINFENG 权利人:PETROCHINA CO LTD 摘要:A preparation method for a cobalt-iridium nanocrystal comprises: mixing an iridium salt, an organic ligand, a reducing solvent and a centrifugal liquid to form a first precursor, and maintaining the temperature of the first precursor; and mixing the first precursor with a cobalt salt in a protective atmosphere to form a second precursor, and maintaining the temperature to carry out a reaction to obtain the cobalt-iridium nanocrystal. According to the preparation method, a centrifugal liquid is used as a raw material, improving the yield, crystallinity and electrocatalytic activity of the cobalt-iridium nanocrystal, and reducing the synthesis cost. The present invention also relates to a cobalt-iridium nanocrystal and a water electrolysis catalyst.
