Abstract

Two-dimensional (2D) metal borides are a class of ceramic materials with diverse structural and topological properties. These diverse material properties of metal borides are what forms the basis of their interdisciplinarity and their applicability in various research fields. In this study, we highlight which fundamental and practical parameters need to be taken into consideration when designing nanomaterials for specific applications. A simple one-pot chemical reduction method was applied for the synthesis of manganese mono-boride nanoflakes at room temperature. How the specific surface area and boron-content of the as-synthesized manganese mono-boride nanoflakes influence their magnetic and electrocatalytic properties is reported. The sample with the highest specific surface area and boron content demonstrated the best magnetic and electrocatalytic properties in the HER. Whereas the sample with the lowest specific surface area and boron content exhibited the best electric conductivity and electrocatalytic properties in the OER.

摘要

二维（2D）金属硼化物是一类具有多样结构和拓扑性质的陶瓷材料。金属硼化物这些多样的材料特性构成了它们跨学科性以及在各个研究领域适用性的基础。在本研究中，我们强调了在为特定应用设计纳米材料时需要考虑哪些基本和实际参数。采用一种简单的一锅化学还原法在室温下合成了一硼化锰纳米片。报道了所合成的一硼化锰纳米片的比表面积和硼含量如何影响其磁性能和电催化性能。比表面积和硼含量最高的样品在析氢反应中表现出最佳的磁性能和电催化性能。而比表面积和硼含量最低的样品在析氧反应中表现出最佳的导电性和电催化性能。
