Conventional two-dimensional materials either have natural layered structures or are produced, with large surface areas, via physical or chemical synthesis. However, to form a two-dimensional material from a non-layered material, a method different from the existing ones is required. In this study, a surfactant-assisted method was utilized to synthesize Zn(OH) (a nonlayered transition metal oxide) nanosheets. This study described the synthesis of Zn(OH) nanosheets using an anionic sulfate layer and demonstrated a method of controlling the thickness and shape of the synthesized nanosheets by varying the surfactant concentration. Further, the characteristics of oxygen evolution reaction using ZnO/Zn(OH) nanosheets, obtained by annealing the synthesized sheets, as catalysts were studied.
传统的二维材料要么具有天然的层状结构，要么通过物理或化学合成方法制备出具有大表面积的材料。然而，要从非层状材料形成二维材料，需要一种不同于现有方法的途径。在本研究中，采用了一种表面活性剂辅助的方法来合成Zn(OH)（一种非层状过渡金属氧化物）纳米片。本研究描述了使用阴离子硫酸盐层合成Zn(OH)纳米片的过程，并展示了一种通过改变表面活性剂浓度来控制合成纳米片厚度和形状的方法。此外，还研究了将通过对合成的薄片进行退火处理得到的ZnO/Zn(OH)纳米片用作催化剂时的析氧反应特性。
