一种具备电解水催化功能的钛基抗结垢阴极制备方法

Resumen de: CN121575432A

本发明属于电极技术领域，公开了一种具备电解水催化功能的钛基抗结垢阴极制备方法，步骤如下：在钛网基底表面构建微结构；在微结构上负载过渡金属催化剂；在具有催化功能的微结构材料表面涂覆惰性涂层。这种阴极表面的惰性涂层会阻碍电子与水分子接触，使仅未被惰性涂层覆盖的微结构尖端充当晶体的初始成核位点。当晶体生长至微米级时，其与微结构尖端的附着力会减弱。同时，电解水产生的气泡会沿惰性涂层生长，并在微结构尖端附近破裂，推动晶体自发脱落，避免沉淀在电极表面堆积。同时微结构上负载的金属阳离子如Ni2+、Co2+可以降低电解海水的过电位。这两种性质使得该阴极可以应用于海水中镁资源的提取。
