针对电解水制氢成本高的挑战,海南大学联合中国科学院宁波材料技术与工程研究所,突破直接电解天 然海水制氢提镁技术,实现氢气和氢氧化镁联产,大幅降低氢气生产成本。北京时间12月12日,相关研 究成果在国际学术期刊《自然·通讯》发表。 当前,电解淡水制氢成本高、资源消耗大。海水是理想的制氢原料,但其中富含的镁离子在电解过程中 易在电极表面沉积,导致电极快速失效。 科研人员研制了一种像"不粘锅"的新型电极,通过在铂电极表面添加碘离子,利用静电排斥力,使电解 海水析氢反应中生成的氢氧化镁远离电极表面并沉淀到溶液里,有效防止电极表面结垢。目前,科研团 队开发的海水制氢提镁工程样机,可在天然海水中稳定运行超过5000小时。 新型电极在海水析氢反应中能有效防止氢氧化镁沉积,从而稳定运行。新华社发(海南大学海洋清洁能 源创新团队供图) 据海南大学海洋清洁能源创新团队负责人田新龙介绍,该项技术在常温下即可进行,能够实现高纯度氢 气和氢氧化镁的联产,且成本比传统高能耗工艺低。试验数据显示,产生1公斤氢气的同时,可提取约 15公斤高纯度氢氧化镁,而氢氧化镁的价值可基本抵消制氢成本。 科研人员表示,这项突破性技术有望助力实现"绿氢"的 ...
