Thiosemicarbazide and its derivatives as promising corrosion inhibitors: A Mini-Review

Abstract

Thiosemicarbazide is a promising corrosion inhibitor due to its excellent inhibitive properties, low toxicity, and cost-effectiveness. This mini-review highlights the chemical structure, properties, and corrosion inhibition mechanism of thiosemicarbazide. Various experimental studies have been carried out to investigate the corrosion inhibition performance of thiosemicarbazide on different metal surfaces, such as carbon steel, aluminum, and copper, in different corrosive environments, including acidic, alkaline, and saline solutions. The review also discusses the effect of different parameters, such as concentration, immersion time, temperature, and pH, on the corrosion inhibition efficiency of thiosemicarbazide. Overall, the results show that thiosemicarbazide is a highly effective corrosion inhibitor, and its inhibition performance is comparable to other well-known inhibitors. Finally, the review concludes by highlighting the future research directions in the field of thiosemicarbazide-based corrosion inhibitors.
