Using a flexible bis (triazole) ligand BBPTZ, where BBPTZ = 4,4'- bis (1,2,4-triazol-1-ylmethyl) biphenyl, a novel compound of [Ni2(BBPTZ)4][β-Mo8O26] (1) based on [NiN4O2]2+ secondary building unit (SBU) and [β-Mo8O26]4 cluster was synthesized by hydrothermal method. In compound 1, the [NiN4O2]2+ SBUs serving as 2-connected joints were directly connected [β-Mo8O26]4 clusters forming 1D inorganic strips. The adjacent strips were assembled through two types of BBPTZ ligands along the c axis, giving rise to 2D layers. It exhibits not only good thermal stability but also bifunctional electrocatalytic activity. When using it as the electrocatalyst for the electrochemical sensing for bromate, it shows a broad sensor range (1.35–4.75 mM) and comparable sensitivity of 62.39 µA cm−2 mM−1. Moreover, it also exhibits a remarkable activity towards the hydrogen evolution reaction, with a 248 mV onset potential, a Tafel slope of 131 mV dec−1, and a η10 of 386 mV.

基于[β-Mo8 O 26] 4−团簇和[NiN 4 O 2] 2+次级结构单元的新型化合物的合成,结构和电催化作用

使用柔性双(三唑)配体BBPTZ,其中BBPTZ = 4,4'-双(1,2,4-三唑-1-基甲基)联苯,[Ni 2(BBPTZ)4 ] [β-Mo 8 ø 26 ](1基于[NIN)4 Ò 2 ] 2+次级结构单元(SBU)和[β-沫8 ø 26 ] 4 -簇通过水热法合成。在化合物1中,[NIN 4 Ò 2 ] 2+的SBU用作-2-连接接头被直接连接[β-沫8 ø 26 ] 4成簇形成一维无机带。沿c轴通过两种类型的BBPTZ配体组装相邻的条带,从而产生2D层。它不仅具有良好的热稳定性,而且还具有双功能电催化活性。当将其用作溴酸盐电化学检测的电催化剂时,它显示出较宽的传感器范围(1.35–4.75 mM)和相当的灵敏度62.39 µA cm -2  mM -1。此外,它也表现出朝向析氢反应的显着活性,与248毫伏开始电位,131毫伏分解的塔菲尔斜率-1,和η 10 386毫伏。
