用于水分解的 K3Ta3B2O12 光催化材料是使用新型水溶性 Ta-过氧乳酸盐复合物通过水溶液工艺制备的。使用水作为加工溶剂对于防止挥发性硼化合物的形成以及通过溶液技术合成化学计量单相材料至关重要。当使用化学计量的 Ta:La = 1:2 的乳酸 (LA) 制备 Ta-过氧乳酸盐配合物时，K3Ta3B2O12 的光催化水分解活性最高。此外，当使用 NiO 作为助催化剂时，K3Ta3B2O12 的光催化水分解活性得到了提高。本工作中制备的材料表现出的最高光催化氢和氧析出速率为H2：392μmol/h和O2：192μmol/h。
The K3Ta3B2O12 photocatalytic material for water splitting was prepared by an aqueous solution-based process using a novel water soluble Ta-peroxolactate complex. Use of water as a processing solvent is essential to prevent formation of volatile boron compounds and to synthesize the stoichiometric single phase material by a solution technique. Photocatalytic activity of K3Ta3B2O12 for water splitting was the highest when a stoichiometric amount of lactic acid (LA) with Ta:La = 1:2 was used for preparation of the Ta-peroxo lactate complex. Additionally, activities of K3Ta3B2O12 in the photocatalytic water splitting have been improved when NiO was used as a co-catalyst. The highest photocatalytic hydrogen and oxygen evolution rates exhibited by the materials prepared in this work were H2: 392 μmol/h and O2: 192 μmol/h.
