摘要：

Dibenzo [1,4,8,11] tetraaza [14] annulene nickel (TAA-Ni) has been synthesized and its inhibitive behavior on mild steel in 1 M HCl was firstly investigated by gravimetric, potentiodynamic and impedance method. The potentiodynamic curves indicate the TAA-Ni mainly acted as mixed type inhibitor on electrochemistry in acid media. The weight loss result indicates TAA-Ni is good inhibitor in acid solution with the temperature changing from 303 K to 333 K. The XPS experiment indicates the protonation of TAA-Ni and its chemical adsorption on steel surface. (C) 2008 Elsevier Ltd. All rights reserved.
