“…Due to strong affinity towards accommodating alkali metal cations, α-MoO 3 can be utilized as a selective ion sensing material. Zakharova et al [194] reported a detail study about the ion-selective properties of α-MoO 3 nanorods for alkali metal cation sensing. The solid-state ion sensitive electrode showed selectivity in the concentration ranges of 10 -1 to 10 -5 M for the alkali metal cations Li + , Na + , K + , Rb + , and Cs + .…”

“…The solid-state ion sensitive electrode showed selectivity in the concentration ranges of 10 -1 to 10 -5 M for the alkali metal cations Li + , Na + , K + , Rb + , and Cs + . [194] Alkali compounds of molybdenum bronzes were investigated for Na + sensing due to their unique structural characteristic for providing fast ion diffusion channels. [195] They demonstrated better rigidity and more stable sensing performances at relatively high temperatures compared to conventional glass based electrodes, which made them promising candidates for chemical sensing in specific categories such as food and clinical applications.…”

The properties and applications of molybdenum oxides are reviewed in depth. Molybdenum is found in various oxide stoichiometries, which have been employed for different high-value research and commercial applications. The great chemical and physical characteristics of molybdenum oxides make them versatile and highly tunable for incorporation in optical, electronic, catalytic, bio, and energy systems. Variations in the oxidation states allow manipulation of the crystal structure, morphology, oxygen vacancies, and dopants, to control and engineer electronic states. Despite this overwhelming functionality and potential, a definitive resource on molybdenum oxide is still unavailable. The aim here is to provide such a resource, while presenting an insightful outlook into future prospective applications for molybdenum oxides.

The proposed electrode was found much more suitable than many of the other alternatives given in the literature as regard to the linear working range and slope [1,[6][7][8][9][10][11][12][13][14]16,[18][19][20][22][23][24][25]30,32,33]. The comparison of response characteristics of some different type of pH sensing electrodes together with the proposed electrode are given in Table 2.…”

“…Although pH-sensitive glass electrode has distinguished response characteristics and has been in use for such a long period, it has certain setbacks such as its high resistance, fragility, its instability in hydrofluoric acid or fluoride solutions, alkaline and acid errors and its unsuitability to serve as a microelectrode for biological applications [4,5]. Accordingly, the studies to develop non-glass pH-sensitive electrodes such as solid contact electrodes (SCE's) [1,[6][7][8][9][10][11][12][13], coated wire electrodes (CWE's) [13,14], field effect transistors (FET's) [15,16], nanorod based electrodes [17,18] and polymeric membrane electrodes [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] have gained interest. Among these, PVC membrane electrodes are the preferred ones due to their low electrical resistance and ease of construction [31,32].…”

The electrode exhibited a slope of 44.1±1.7 mV/pH in the pH range 1.7-9.5 at 20±1 °C. Furthermore, it was observed that the electrode had good repeatability and reproducibility with a response time of 15 s and a lifetime of at least 12 months. Also, it was found to display good selectivity for H + ions in the presence of various ions. The applicability of the proposed electrode for the determination of titratable acidity in some beverages (orange juice, apple juice, fizzy drink, beer, wine and vinegar) was illustrated. It was seen that there were no significant differences between the results obtained with the proposed electrode and the traditional glass pH electrode at the 95% CL (confidence level). As a consequence, it was seen that the electrode based on ZFNCa could be successfully used as an alternative for glass electrode to determine the titratable acidity in beverages.
