以3水合硝酸铜和5-甲基-2-噻吩甲酸为原料，在4，4-联吡啶存在下，采用溶剂热法合成了铜基金属有机骨架材料(CuMOF)，并对其结构进行了表征。实验结果表明，铜-钼系金属氧化物能显著降低碳钢的腐蚀速度，起到保护碳钢的作用。随着溶液中铜-MOF浓度的增加，缓蚀率提高，当浓度为50 mg/L时，缓蚀率达到82.42%。我们的研究结果证实，合成的铜-金属氧化物纤维能够吸附并覆盖在碳钢表面，形成致密的保护膜，从而抑制其腐蚀。(C)2020年由爱思唯尔出版。
Cu-based metal-organic framework materials (Cu-MOFs) were synthesized by reacting copper nitrate trihydrate with 5-methyl-2-thiophenecarboxylic acid in the presence of 4,4-bipyridyl via the solvothermal method, and the structure of the resulting materials was characterized. The experimental results showed that Cu-MOFs could significantly reduce the corrosion rate of carbon steel and protect it from corrosion. Increasing the concentration of Cu-MOFs in the test solution incased inhibition efficiency, which reached 82.42% at 50 mg/L Cu-MOFs. Our findings confirmed that the synthesized Cu-MOFs could adsorb into and cover the surface of carbon steel to form a dense protective film that inhibits its corrosion.
