“…3 f also established improved electrochemical performance of CdFe 2 O 4 . Typically, in EIS, the charge transfer resistance (Rct) is represented by the semi-circle of the Nyquist plot; and the smaller the Rct, the better the electron/ion transfer on the substrate and electrolyte interface 32 . The Rct for CdFe 2 O 4 was 343 Ω while that of bare GE was 596 Ω (Fig.…”

Clean energy is highly needed at this time when the energy requirements are rapidly increasing. The observed increasing energy requirement are largely due to continued industrialization and global population explosion. The current means of energy source is not sustainable because of several reasons, most importantly, environmental pollution and human health deterioration due to burning of fossil fuels. Therefore, this study develops a new catalyst for hydrogen and oxygen evolution by water splitting as a potential energy vector. The binary metal oxide catalyst CdFe2O4 was synthesized by the solventless solid-mechanical alloying method. The as-prepared catalyst was well characterized by several methods including field emission scanning electron microscopy (FESEM), X-ray diffraction spectroscopy (XRD), X-ray photoelectron spectroscopy (XPS), Fourier Transform infrared red spectroscopy (FTIR), energy dispersive X-ray spectroscopy (XEDS). The as-prepared catalyst, CdFe2O4 was successfully applied for water electrolysis at a moderate overpotential (470 mV). Specifically, the onset potential for the oxygen and hydrogen evolution reactions (OER and HER) were 1.6 V/RHE and 0.2 V/RHE respectively (vs. the reversible hydrogen electrode). The electrode potential required to reach 10 mA/cm-2 for OER (in alkaline medium) and HER (in acidic medium) was 1.70 V/RHE (corresponding to overpotential η = 0.47 and − 0.30 V/RHE (η = − 0.30 V) respectively. Similarly, the developed OER and HER catalyst displayed high current and potential stability for a period of 12 h. This approach is seen as the right track of making water electrolysis for hydrogen energy feasible through provision of low-energy requirement for the electrolytic process. Therefore, CdFe2O4 is a potential water splitting catalyst for hydrogen evolution which is a clean fuel and an antidote for world dependence on fossil fuel for energy generation.

“…Knowing the amount of nitrite can help in assessing the toxicity level and ensuring the value is below or within the acceptable limit of detection. As a result, several methods have reported on nitrite detection, based on kinetic studies and quantitative analysis [33][34][35][36][37][38].…”

“…4 In fact, the maximum allowable NO 2 concentration beyond which the respiratory system of non-asthmatic people starts getting affected is less than 3 ppm. [5][6][7][8][9][10][11] Although conventional metal oxide semiconductor NO 2 sensors have satisfactory sensitivity, they have a high operating temperature (>200 °C) and poor selectivity. [12][13][14][15][16] In general, efficient gas sensors are characterized by fast response, high sensitivity, good selectivity, low operating temperature, and stability at room temperature (RT).…”
