Abstract Aqueous extract of Citrus reticulata peels (CRE) mediated synthesis of nickel nanoparticles (CRE-NiNPs), characterization and application of the obtained composite as microbial and acid corrosion inhibitor is reported. The CRE-NiNPs were stable, non-agglomerated, monodispersed, round-shaped and of 40 − 55 nm size. With surfaces rich in O and N sites, CRE-NiNPs efficiently adsorbs on and inhibits X80 steel corrosion in I M HCl solution with efficiency of 87.3% and 80.6% at 30 and 60 °C, respectively. The nanoparticle also affords 3-log reduction in Desulfovibrio sp population and 73.2% inhibition efficiency at 3.21 mg/L minimum inhibitory concentration. Potentiation with D-tyrosine increases the efficiency to 79.7% and 5-log reduction in microbial population. Microbial corrosion inhibition is attributed to ease of penetration through bacteria cells to subdue their metabolic via physical and chemical adsorption mechanisms. Compared to the crude, CRE-NiNPs is more thermally stable, more efficient and affords better surface protection at high temperature. Highlights Citrus reticulata peels extract (CRE) mediated nickel nanoparticles (CRE-Ni NPs) were synthesized and characterized. CRE-Ni NPs richer in N and O sites, more stable and efficiently inhibits corrosion at high temperatures than CRE Small size enhances high efficiency against Desulfovibrio sp with over 3-log population reduction Adsorption of CRE-Ni NPs is by combined physisorption and chemisorption enabled by C=C, C=O, C–O, O–H and N–H sites

摘要 报道了柑橘皮 (CRE) 介导的镍纳米粒子 (CRE-NiNPs) 的水提物合成、所得复合材料作为微生物和酸腐蚀抑制剂的表征和应用。CRE-NiNPs 是稳定的、非团聚的、单分散的、圆形的,尺寸为 40 - 55 nm。由于表面富含 O 和 N 位点,CRE-NiNPs 在 IM HCl 溶液中有效吸附并抑制 X80 钢腐蚀,在 30 和 60 °C 下的效率分别为 87.3% 和 80.6%。在 3.21 mg/L 的最低抑制浓度下,纳米颗粒还使脱硫弧菌 sp 种群减少了 3-log,抑制效率为 73.2%。D-酪氨酸的增强将效率提高到 79.7%,微生物数量减少 5-log。微生物腐蚀抑制归因于易于穿透细菌细胞以通过物理和化学吸附机制抑制其代谢。与原油相比,CRE-NiNPs 具有更高的热稳定性、更高的效率并在高温下提供更好的表面保护。亮点 柑橘皮提取物 (CRE) 介导的镍纳米粒子 (CRE-Ni NPs) 已合成并表征。CRE-Ni NPs 在 N 和 O 位点上更丰富,在高温下比 CRE 更稳定,更有效地抑制腐蚀 小尺寸提高了对脱硫弧菌 sp 的效率,数量减少了 3-log CRE-Ni NPs 的吸附是通过物理吸附和化学吸附的结合通过 C=C、C=O、C-O、O-H 和 N-H 位点 CRE-NiNPs 具有更高的热稳定性、更高的效率,并在高温下提供更好的表面保护。重点合成并表征了柑橘皮提取物 (CRE) 介导的镍纳米粒子 (CRE-Ni NP)。CRE-Ni NPs 在 N 和 O 位点上更丰富,在高温下比 CRE 更稳定,更有效地抑制腐蚀 小尺寸提高了对脱硫弧菌 sp 的效率,数量减少了 3-log CRE-Ni NPs 的吸附是通过物理吸附和化学吸附的结合通过 C=C、C=O、C-O、O-H 和 N-H 位点 CRE-NiNPs 具有更高的热稳定性、更高的效率,并在高温下提供更好的表面保护。亮点 柑橘皮提取物 (CRE) 介导的镍纳米粒子 (CRE-Ni NPs) 已合成并表征。CRE-Ni NPs 在 N 和 O 位点上更丰富,在高温下比 CRE 更稳定,更有效地抑制腐蚀 小尺寸提高了对脱硫弧菌 sp 的效率,数量减少了 3-log CRE-Ni NPs 的吸附是通过物理吸附和化学吸附的结合通过 C=C、C=O、C-O、O-H 和 N-H 位点
