The inorganic nanoparticlebased anticorrosive coating on steel drew important attention to its large surface-to-volume ratio. The primary aim of this study is to synthesize and characterize t-ZrO2 nanoparticles at an optimized annealing temperature and evaluate their structural, morphological, and optical properties. Additionally, the study investigates their effectiveness as a corrosion inhibitor for carbon steel in 1 MH2SO4. The study explores the cheap, facile, green synthesis oft-ZrO2 nanoparticles (NPs) through bark extract from the gum arabic plant (Acacia nilotica) for anticorrosive coatings on carbon steel. X-ray diffraction (XRD) analysis confirms the tetragonal phase structure and the crystallite size, calculated using Scherrer’s formula, is found to be 8.1 nm. Fourier-transform infrared (FT-IR) spectroscopy reveals the presence of Zr-O bonding along with organic residues from plant extracts, confirming the formation oft-ZrO2 NPs. Field emission scanning electron microscopy (FESEM) images confirm a rock stone-like structure, while energy dispersiveX-ray (EDX) spectroscopy verifies the presence of Zr and O elements. The study further investigates the corrosion inhibition efficiency oft-ZrO2 NPs on carbon steel in 1 M H2SO4. The atomic force microscopy (AFM) analyses reveal a smoother surface with reduced roughness in the presence of the inhibitor. Electrochemical measurements, including weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS), confirm a significant reduction in corrosion rate. The inhibition efficiency reaches 95.2% at 200 ppm of 0.2 M  \nt-ZrO2 NPs, with an increased charge transfer resistance (Rct) of 14,715 Ω cm2 and a reduced doublelayer capacitance (Cdl ) of 0.631 × 10⁸ F/cm2. These findings demonstrate that t-ZrO2 NPs act as an effective corrosion inhibitor for carbon steel in acidic environments.  \nKeywords Green synthesis, Acacia nilotica, t-ZrO2 NPs, Anticorrosion study  \n1PG and Research, Department of Chemistry, Jamal Mohamed College (Autonomous), Affiliated to Bharathidasan University, Tiruchirappalli, Tamil Nadu 620 020, India. 2Department of Physics, Nandha Engineering College, Erode, Tamil Nadu 638 052, India. 3Department of Chemistry, Paavai Engineering College (Autonomous), Namakkal, Tamil Nadu 637 018, India. 4Department of Chemistry, Sri Sairam Engineering College (Autonomous), West Tambaram, Chennai, Tamil Nadu 600 044, India. 5Advanced Institute of Manufacturing With High-Tech Innovations and Department of Mechanical Engineering, National Chung Cheng University, Chia-Yi 621301, Taiwan. 6Centre for Materials Science, Karpagam Academy of Higher Education, Coimbatore, Tamil Nadu 641021, India. 7Department of Physics, Karpagam Academy of Higher Education, Coimbatore, Tamil Nadu 641021, India. 8Department of Chemistry, Karpagam Academy of Higher Education, Coimbatore, Tamil Nadu 641021, India. 9Centre for Material Chemistry, Karpagam Academy of Higher Education, Coimbatore, Tamil Nadu 641021, India. 10Centre for Research Impact & Outcome, Chitkara University Institute of Engineering and Technology, Chitkara University, Rajpura, Punjab 140401, India. 11Instituto de Alta Investigación, Universidad de Tarapacá, 1000000 Arica, Chile. 12School of Chemical Engineering, Yeungnam University, Gyeongsan 38541, Republic of Korea. 13Department of Biochemistry, Saveetha Medical College and Hospital, Saveetha Institute of Medical and Technical Sciences, Chennai, Tamil Nadu, India. 14Marwad","cbCaidcvqJ7rP6sM","https://ap.wps.com/l/cbCaidcvqJ7rP6sM","pdf",3375663,16,"English","# Introduction\n## Nanotechnology and nanoparticles\n## Metal oxide nanoparticles and zirconia\n# Materials and Methods\n## Green synthesis of t-ZrO2 nanoparticles\n## Characterization techniques\n# Corrosion Inhibition Evaluation\n## Electrochemical measurements in H2SO4\n## Inhibition efficiency and surface effects","[{\"question\":\"How are t-ZrO2 nanoparticles synthesized in the study?\",\"answer\":\"t-ZrO2 nanoparticles are synthesized using a green, facile method based on bark extract from the gum arabic plant (Acacia nilotica), followed by optimized annealing.\"},{\"question\":\"Which characterization methods confirm the formation and properties of t-ZrO2?\",\"answer\":\"XRD confirms the tetragonal phase, FT-IR indicates Zr–O bonding, FESEM/EDX verifies morphology and Zr/O elements, and AFM shows reduced roughness with the inhibitor.\"},{\"question\":\"How effective are t-ZrO2 nanoparticles as a corrosion inhibitor for carbon steel in 1 M H2SO4?\",\"answer\":\"Electrochemical results show a strong reduction in corrosion rate, with inhibition efficiency reaching 95.2% at 200 ppm and corresponding changes in charge transfer resistance and double-layer capacitance.\"}]","Nanoengineered t-ZrO2 coatings for superior corrosion resistance on steel surfaces | PDF",1790743804]
