Benzotriazole (BTAH) has been used as a copper corrosion inhibitor since the 1950s; however, the molecular level detail of how inhibition occurs remains a matter of debate. The onset of BTAH adsorption on a Cu(111) single crystal was investigated via scanning tunnelling microscopy (STM), vibrational spectroscopy (RAIRS) and supporting DFT modelling. BTAH adsorbs as anionic (BTA(-)), CuBTA is a minority species, while Cu(BTA)2, the majority of the adsorbed species, form chains, whose sections appear to diffuse in a concerted manner. The copper surface appears to reconstruct in a (2 × 1) fashion.
苯并三唑 (BTAH) 自 20 世纪 50 年代以来一直被用作铜腐蚀抑制剂；然而，其抑制作用发生的分子水平细节仍然存在争议。通过扫描隧道显微镜 (STM)、振动光谱 (RAIRS) 和支持的 DFT 建模研究了 BTAH 在 Cu(111)单晶上的吸附起始。BTAH 作为阴离子 (BTA(-)) 吸附，CuBTA 是少数物种，而 Cu(BTA)2 是吸附物种的主要部分，形成链，其部分似乎以协同方式扩散。铜表面似乎以 (2×1) 的形式重构。
