Abstract

Sustainable and scalable Calcium zinc titanate (CaZnTi₂O₄ (CZT)) nanomaterial were investigated. Characterizations of CZT nanomaterial reveals that, it has a polycrystalline nature with crystallite size ̴ 48 nm and band gap was estimated to be 3.25 eV. The CZT NPs material proved to be an efficient photocatalyst by degrading 80% and 78.12% respectively for congo red and MB dyes under UV light. Energy storage and heavy metal ions sensing properties of CZT nanomaterial was investigated by developing a CZT modified carbon paste electrode and found that it exhibits a specific capacitance (C_sp) of 900 F/g and 90% stable after 800 cycles. Electrochemical sensing analysis revealed that limit of detection and quantification were found to be 5.61 μM and 18.70 µM for lead, and 1.18 μM and 3.9 μM for mercury respectively. These results make the nanomaterial a promising candidate for environmental and energy applications.

单相三金属钛酸钙锌（CaZnTi2O4）多功能纳米材料：光催化染料降解、储能和传感应用

研究了可持续、可扩展的钛酸钙锌（CaZnTi2O4 (CZT)）纳米材料。对CZT纳米材料的表征表明，该材料具有多晶性质，晶体尺寸为48 nm，带隙约为3.25 eV。在紫外光下，CZT NPs材料对刚果红和MB染料的降解率分别为80%和78.12%，是一种高效的光催化剂。通过研制CZT修饰碳糊电极，研究了CZT纳米材料的储能和重金属离子传感性能，发现其比电容（Csp）为900 F/g，循环800次后稳定性为90%。电化学传感分析结果表明，铅的检出限和定量限分别为5.61 μM和18.70 μM，汞的检出限和定量限分别为1.18 μM和3.9 μM。这些结果使纳米材料成为环境和能源应用的有希望的候选材料。
