Microbiologically influenced corrosion (MIC) accounts for a large proportion of industrial steel corrosion, among which the most representative microorganism is sulfatereducing bacteria (SRB). The direct application of the fungicides may cause high utilization dosage, increased bacterial resistance, and environmental pollution and cannot realize the effective longlasting antimicrobial and corrosion inhibition performance. Herein, a novel kind of nanocapsule with both bactericidal and corrosion inhibition functions is developed. The hollow mesoporous silica (HMSNs) is used as the carrier and encapsulated with benzotriazole (BTA) inhibitors; their surface microchannels are sealed with the bactericide metronidazole (MNZ)-loaded ZIF-8 nanovalve. The high-performance liquid chromatography results confirm that the encapsulation amounts of MNZ and BTA in the nanocapsules are 7.67% and 4.20%, respectively. Moreover, the as-prepared BTA-HMSN/ZIF-8-MNZ nanocapsules exhibit a typical sulfide ion-responsive characteristic. The release rate of the encapsulated MNZ and BTA rises with the increased sulfide-ion concentrations, and the cumulative release amount reaches 80% after 24 h when the sulfide-ion concentration attains 2 mM. Furthermore, the antimicrobial performance of BTA-HMSN/ZIF-8-MNZ nanocapsules is evaluated in SRB solutions. The survival SRB amounts decrease evidently with the increased nanocapsule concentration, and the antibacterial efficiency is nearly 100% at a concentration of 250 μg•mL −1 . The weight loss test and surface analysis also confirm the excellent corrosion inhibition ability of the BTA-HMSN/ZIF-8-MNZ nanocapsules to Q235 steels, whose inhibition efficiency is up to 89.23% after 8 h of immersion in a corrosive environment after the addition of 12 mg•mL −1 of BTA-HMSN/ZIF-8-MNZ nanocapsules. Meanwhile, the Q235 steel maintains a smooth and uniform surface with the protection of BTA-HMSN/ZIF-8-MNZ nanocapsules. Overall, the combination of MNZ bactericides and BTA corrosion inhibitors greatly strengthens the antimicrobial and corrosion inhibition performance of the nanocapsules, and this kind of intelligent sulfide ion-responsive protective system also provides insights for retarding MIC in a complex corrosive environment.

“…This indicates that HEDP initially accelerated the corrosio reaction rate of carbon steel in the presence of iron bacteria, thereby diminishing the co rosion inhibition effect. According to Figure 2, the corrosion rate of carbon steel under the IB+HEDP condition was approximately 60% lower than that under the IB working condition, suggesting that HEDP effectively reduced the corrosion rate in the presence of iron bacteria, surpassing the corrosion inhibition effect observed in the SRB system [17]. The corrosion inhibition behavior of HEDP in the iron bacteria system reveals distinct phases.…”

“…Observations from Figure 7 reveal that approximately 35% of FeOOH did not convert to Fe 3 O 4 as expected in the IB+HEDP condition, leading to an increase in FeOOH converted to Fe 2 O 3 . Li et al's study suggests that HEDP blocks the production of reducing bacterial iron transporters and reduces iron uptake [17]. Therefore, the comprehensive analysis of Sections 3.2 and 3.3 suggests that the utilization of HEDP by attached iron bacteria hampers the ability of IRB to obtain energy by reducing Fe 3+ , consequently reducing their activity [43].…”

Regenerated water serves as a supplementary source for circulating cooling water systems, but it often fosters microbial growth within pipelines. Given its widespread use as a corrosion inhibitor, understanding HEDP’s efficacy in microbial environments and its impact on microorganisms is imperative. This study established an iron bacterial system by isolating and enriching iron bacteria. Through a comprehensive approach incorporating corrosion weight loss analysis, XPS analysis, SEM electron microscopy, as well as microbial and electrochemical testing, the corrosion inhibition behavior and mechanism of HEDP within the iron bacterial system were investigated. The findings reveal that within the iron bacterial system, HEDP achieves a corrosion inhibition rate of 76% following four distinct stages—weakening, strengthening, stabilizing, and further strengthening—underscoring its robust corrosion inhibition capability. Moreover, HEDP enhances the density of biofilms and elevates the activation energy of carbon steel interfaces. It alternates with oxygen to continuously suppress the activity of IRB while gradually inhibiting the activity of IOB. This process culminates in a corrosion inhibition mechanism where cathodic inhibition predominates, supported by anodic inhibition as a complementary mechanism.
