Abstract The innovation of the graphene (G) marks key revolutionary events in the science and technology. The normal materials conversion to the two dimensional materials (2DMs), is known as modern day “alchemy” was extended to the most of groups in periodic table. The monoelemental, atomically thin 2DMs, called “Xenes” (“ene” Latin word, means nanosheets (NSs), here, X = different possible group elements (group-IIIA-IVA)) are newly invented edge of the materials family in which one of the most active area is 2DMs investigation. The 2D-Xenes material offers novel properties for the modern nanodevices applications. Any new form of the 2DMs entry into mainstream Xenes would likely compete with today's electronic technology. The metallic 2D-borophene is experimentally formed; subsequent by the theoretical calculations has high in-plane anisotropy together with numerous enviable features like, the 2D-G and phosphorene (2D-BP). As a synthetic 2DMs, the structural properties of 2D-borophene cannot be deduced from bulk boron (B), means that the fundamental defects of the 2D-borophene persisted unknown. The modern highly sensitive potential synthesis and characterization techniques offer an opportunity for investigating the theoretically predicted 2D-Xenes, with atomic precision under idealized conditions. Experimental based theoretically predicted, synthetic 2D-Xenes of the group-IIIA (Borophene (2D-B)) material has been investigated, just like a metallic material. Thus, it is potentially rendering them as potential candidates for the future electrocatalytic based nanodevices, especially potential applications as a catalyst, electrode material, energy storage materials in batteries/superconductors, and so on. In this topical review, we will briefly present various aspects of the 2D-borophene, group-IIIA 2D-Xenes. Thereafter, we will explain different potential methods to synthesize 2D-borophene Xenes, provide a concise summary of the main achievements about their properties, that have been obtained by theoretical simulations as well as by experimental investigations and finally we will discuss the potential applications of the 2D-borophene Xenes, for fundamentally oriented studies. Although, this material investigations and devices applications are still at an early stage, but theoretical calculations and some experimental measurements, provided that, it is complementary to normally used electrocatalytic nanomaterials as well as 2DMs (i.e., layered bulk-derived), with their novel properties and predicted applications.

2D-硼烯氙的合成、性质和新型电催化应用

摘要 石墨烯（G）的创新标志着科技领域的重大革命性事件。普通材料向二维材料 (2DM) 的转换，被称为现代“炼金术”，已扩展到元素周期表中的大多数族群。单元素、原子级薄的 2DM，称为“Xenes”（“ene”拉丁词，意思是纳米片 (NS)，这里，X = 不同可能的族元素（IIIA-IVA 族））是新发明的材料家族的边缘，其中最活跃的领域之一是 2DMs 调查。2D-Xenes 材料为现代纳米器件应用提供了新的特性。任何进入主流 Xene 的 2DM 新形式都可能与当今的电子技术竞争。金属 2D-硼烯是通过实验形成的；随后通过理论计算具有高面内各向异性以及许多令人羡慕的特征，例如 2D-G 和磷烯 (2D-BP)。作为合成的 2DM，2D-硼烯的结构特性不能从块状硼 (B) 中推断出来，这意味着 2D-硼烯的基本缺陷仍然未知。现代高灵敏度的潜在合成和表征技术为研究理论上预测的 2D-Xenes 提供了机会，在理想条件下具有原子精度。已经研究了基于实验的理论预测、IIIA 族（硼烯（2D-B））材料的合成 2D-Xene，就像金属材料一样。因此，它有可能使它们成为未来基于电催化的纳米器件的潜在候选者，特别是作为催化剂、电极材料、电池/超导体中的储能材料等的潜在应用。在本专题综述中，我们将简要介绍 2D-硼烯、IIIA 组 2D-Xenes 的各个方面。此后，我们将解释合成 2D-硼烯 Xenes 的不同潜在方法，简要总结通过理论模拟和实验研究获得的有关其性质的主要成就，最后我们将讨论该物质的潜在应用。 2D-borophene Xenes，用于基础研究。虽然，这种材料的研究和设备应用还处于早期阶段，但理论计算和一些实验测量，前提是，
