“…Ti, Al, Nb). 51 Despite the simplicity, the solvent, pH, metal precursor and electrolytes play important roles in electrodeposited material properties. For instance, water is the most used solvent, however it has a limited potential range of 0 V to +1.23 V (vs. SHE), which are related to HER and OER, respectively.…”

pH sensor is one of the sensing principles that can be employed in detection of engine oil deterioration. To avoid unnecessary changing of engine oil while maintaining the oil quality consumed by car’s engine, engine oil deterioration sensor is required to continuously monitor the oil condition. In this work, we fabricated pH sensor sensing layer made up of tantalum thin film. Ta2O5nanotubular was constructed as the medium of interaction to measure the quality of engine oil. Anodization synthesis method was used to fabricate the sensing layer by varying the anodization time. Two samples anodized at 30 min and 60 min were tested in pH buffer solution at pH ranging from 2, 4, 7, 10 and 12. Further characterization using field emission scanning electron microscope (FESEM) was conducted to investigate the surface morphology properties, while X-ray diffraction (XRD) was conducted to obtain crystal properties of Ta2O5nanotubular. A homogeneous Ta2O5nanostructures with cubic crystal structure and pore diameter ranging between 15 to 20 nm was obtained. 30 min sample tested in pH buffer solution has better adsorption of H+ions with linear pH sensitivity of 31.616 mV/pH and good stability. Therefore, anodization method can be an alternative to fabricate pH sensor for oil deterioration detection system.Additionally, other study on chemical sensor for the detection of engine oil deterioration level wasalsodiscussed in this paper.

“…The electrolyte may either dissolve or partially dissolve the anodic oxide. To produce a steady state of oxide formation and dissolution, an anodization parameter should be used to control the rate of oxide production and dissolution where porous metal oxide will grow under these conditions [44].…”

Anodization is one of the simplest synthesis methods that can be employed to generate generous nanostructures metal oxide. Knowing the potential of anodized Tantalum Pentoxide (Ta2O5) to form the desired nanostructure which is capable to produce outstanding performance, the elements and factors influence properties enhancement were gathered. The effect of parameter variation during anodization such as electrolyte composition, voltage variation, and anodization duration was evaluated to inspect the nanostructure formed. The results generated the differences in properties of nanostructures. Characterization methods such as field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Transmission electron microscopy (TEM), Atomic force microscopy (AFM), and X-ray electron spectroscopy (XPS) were used to investigate the structural, electrical, chemical, optical, biological and mechanical properties of anodized Ta2O5. The findings show that anodized Ta2O5 is reliable to be employed as gas sensor, photocatalysis, pH sensor, biomedical materials and humidity sensor due to its superior properties to produce high sensitivity device and increase the efficiency. In this review, a general overview of anodized Ta2O5 is presented which focuses on its fundamental properties, method of synthesis anodized Ta2O5, anodizationparameter optimization, and recent applications in chemical and biological area, along with a discussion on future research directions relevant to this material. It is hoped that by synthesising nanostructures via anodization, the sensing performance will improve and Ta2O5 will be proven as a trustworthy metal oxide material for sensing applications.
