Abstract

Borate based non-centrosymmertic crystals are known for their non-linear optical properties. This study reports BiB₃O₆ glass-ceramics for photocatalysis and piezocatalysis applications. These were fabricated via. melt-quench technique and yellow transparent glass samples were made. Effectiveness of a bismuth-triborate glass-ceramic (BiB₃O₆) in degrading methylene blue (MB) and methyl violet (MV) dye undergoing photocatalysis in the presence of visible light and solar light for MB dye was studied. Degradation observed in photocatalysis was ∼62 % and ∼50 % for MB and MV dye respectively in 240 min whereas, ∼72 % of MB dye was degraded under solar light. Piezocatalysis was examined to assess the extended potential of this material, resulting in approximately ∼76 % degradation of MB dye. Moreover, in synergistic photo-piezocatalysis degradation of ∼88 % was observed. Phytotoxicity was also assessed using the germination index (GI) showing ∼76 %, using heat treated sample.

可见光/太阳光活性透明 BiB3O6 玻璃-陶瓷多元催化剂

以硼酸盐为基础的非新月体晶体因其非线性光学特性而闻名。本研究报告介绍了用于光催化和压电催化应用的 BiB3O6 玻璃陶瓷。这些陶瓷是通过熔融-淬火技术制造的，并制成了黄色透明玻璃样品。研究了一种三硼酸铋玻璃陶瓷（BiB3O6）在可见光和太阳光下通过光催化降解亚甲基蓝（MB）和甲基紫（MV）染料的效果。在 240 分钟的光催化过程中，观察到甲基溴和甲基紫染料的降解率分别为 62% 和 50%，而在太阳光下，甲基溴染料的降解率为 72%。为了评估这种材料的扩展潜力，对其进行了压电催化测试，结果显示甲基溴染料的降解率约为∼76%。此外，在光-压电催化协同作用下，降解率达到了 88%。还使用发芽指数（GI）对植物毒性进行了评估，结果表明，使用热处理样品的发芽指数为 76%。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
