Multifunctionality is of a paramount significance in the case of metal oxide-based material. In the present study, Cu-doped zinc titanates in different Cu/Zn weight ratios were prepared with co-precipitation method to utilize as an adsorbent and a photocatalysts for H₂S removal and dye degradation, respectively. The structural and morphological analyses were carried out using XRD, XPS, SEM and BET. The experiment results showed that the catalysts had a desulfurization ability with the Cu/Zn weight ratio of 0.06:1, which H₂S in the feed was captured with 100% efficiency in N₂ atmosphere at 750 °C during 5 h, also the removal decreased to 57% in a reducing atmosphere at the end of 5 h. The appropriate Cu loading content could lead to the high active and low apparent activation energy. In addition, the Cu-based catalyst showed an excellent photocatalytic activity under UV light irradiation, which the degradation of Orange II (OII) was found to be 80% at the end of 3 h. The metal loading reduced the band-gap and increased oxygen vacancies of zinc titanate. The reactive adsorptive desulfurization and excellent photocatalytic activity results demonstrate Cu loaded zinc titanate as a promising material for multifunctional applications.

在基于金属氧化物的材料的情况下，多功能性至关重要。在本研究中，采用共沉淀法制备了不同Cu / Zn重量比的掺杂Cu的钛酸锌，分别用作吸附剂和光催化剂以去除H ₂ S和降解染料。使用XRD，XPS，SEM和BET进行结构和形态分析。实验结果表明，该催化剂具有Cu / Zn重量比为0.06：1的脱硫能力，该进料中的H ₂ S以100％的效率被N ₂捕获。在750°C的温度下持续5 h，在还原气氛下5 h的去除率降至57％。适当的铜负载量可能导致高活性和低表观活化能。另外，Cu基催化剂在紫外光照射下显示出优异的光催化活性，在3小时结束时发现Orange II（OII）的降解为80％。金属负载降低了钛酸锌的带隙并增加了氧空位。反应性吸附脱硫和出色的光催化活性结果表明，负载铜的钛酸锌是一种有望用于多功能应用的材料。
