The several outstanding properties of boron‐doped diamond electrodes (BDDEs) have allowed their application for various purposes, among them electrochemical sensing. However, the electrochemical response of many redox species on BDDEs can be strongly dependent on whether their surfaces are predominantly hydrogen‐ (HT) or oxygen‐terminated (OT). Fortuitously, electrochemical pretreatments themselves can be used to enrich in situ the BDEE surface in one or the other type of termination. The surface of a cathodically pretreated BBDE (CPT‐BDDE) becomes enriched in HTs, whereas that of an anodically pretreated BDDE (APT‐BDEE) becomes enriched in OTs. Thus, when suitable, the electrochemical activity of a BDDE for a given analyte may be tuned by electrochemical pretreatments, yielding enhanced sensing properties. The main purpose of this review is the compilation and discussion of papers published after 2009 reporting on electroanalytical applications based on a CPT‐BDDE or an APT‐BDDE. Procedures to perform proper electrochemical pretreatments are also discussed.

电化学预处理的掺硼金刚石电极的分析应用
硼掺杂金刚石电极（BDDE）的几种出色性能使其可以用于多种用途，其中包括电化学传感。但是，BDDEs上许多氧化还原物质的电化学响应可能在很大程度上取决于其表面主要是氢（HT）还是氧封端（OT）。幸运的是，电化学预处理本身可以用于原位富集BDEE表面以一种或另一种类型的端接。阴极预处理的BBDE（CPT-BDDE）的表面富含HT，而阳极预处理的BDDE（APT-BDEE）的表面富含OT。因此，当合适时，可以通过电化学预处理来调节BDDE对给定分析物的电化学活性，从而产生增强的感测特性。这篇综述的主要目的是对2009年以后发表的基于CPT-BDDE或APT-BDDE的电分析应用报告的论文进行汇编和讨论。还讨论了进行适当的电化学预处理的程序。
