The aim is to suppress the HSS formation in MDEA solution inaugurally employing a hybrid iron-based nanoparticles (HINP) oxygen scavenger. It was discovered that the oxygen-scavenging performance of a more cost-effective 20 Fe/HZSM5 was one-fold higher than the 20 Fe/MCM-41. The former was verified for its superior structural properties. The Fe2+ on its surface first reacted with DO, preventing DO from oxidizing the MDEA. Consequently, the absence of hydroxyl radicals eliminated the potential of formic acid formation, hence suppressing the MDEA-acid HSS formation. © 2023 Wiley-VCH GmbH. date: 2023 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85169930543&doi=10.1002%2fceat.202300081&partnerID=40&md5=650bf9df2fed296db595183884d50abc id_number: 10.1002/ceat.202300081 full_text_status: none publication: Chemical Engineering and Technology volume: 46 number: 12 pagerange: 2670-2675 refereed: TRUE citation: Chin, S.Y. and Lim, S.F. and Lau, K.K. and Thangavel, M. and Kamaruzaman, M.R.
