Hierarchical microscale materials have received much attention recently. They can find many important applications, including wastewater treatment and energy storage. However, it is still a challenging task to facilely synthesize microscale structures with good size distribution, unique structures and, particularly, tunable composition. Herein, we have prepared a family of 2 × 2 × 2 Pocket Cube-like hierarchical microparticles, with different chemical compositions, including bimetal hydroxide (ZnSn(OH)₆), mixed bimetal oxide and metal oxide (Zn₂SnO₄&SnO₂), carbon coated bimetal oxide and metal (Zn₂SnO₄&Sn@C), all with the same overall mesoscale microstructures. This family of microscale Pocket Cubes, with different chemical compositions and their associated different physiochemical properties, may offer a set of functional materials for many applications. In order to demonstrate their potential applications, we have preliminarily studied their performances in rechargeable batteries and water remediation. Interestingly, these selected Pocket Cubes are electrochemically active toward the reversible storage of both sodium and lithium with comparable performances to those nanoparticles reported, although their sizes are remarkably large on the microscale. We found that the shapes of the microparticles can influence their photocatalytic performances. Our preliminary results suggest that this family of microscale Pocket Cubes, with further optimization and improvement, can find many promising applications, including wastewater treatment and energy storage.

微型2×2×2袖珍立方体系列

分层的微米级材料最近受到了广泛的关注。他们可以找到许多重要的应用，包括废水处理和能量存储。然而，容易地合成具有良好的尺寸分布，独特的结构，特别是可调谐的组成的微米级结构仍然是一项艰巨的任务。在这里，我们准备了一个2×2×2 Pocket Cube状分层微粒族，具有不同的化学组成，包括双金属氢氧化物（ZnSn（OH）₆），混合的双金属氧化物和金属氧化物（Zn ₂ SnO ₄和SnO ₂），碳包覆的双金属氧化物和金属（Zn ₂ SnO ₄＆Sn @ C），都具有相同的整体中尺度微观结构。具有不同化学成分及其相关的不同理化特性的微型口袋多维数据集家族可以为许多应用提供一组功能材料。为了展示其潜在的应用，我们已经初步研究了它们在可充电电池和水修复方面的性能。有趣的是，这些选定的袖珍立方对钠和锂的可逆储存具有电化学活性，其性能与报道的纳米颗粒相当，尽管它们的尺寸在微尺度上非常大。我们发现微粒的形状可以影响它们的光催化性能。我们的初步结果表明，该系列微型袖珍立方体，
