Strategic Electrochemical Determination of Nitrate over Polyaniline/Multi-Walled Carbon Nanotubes-Gum Arabic Architecture.

Significant agricultural and industrial activities necessitate the regular monitoring of nitrate (NO) ions levels in feed and groundwater. The current comparative study discloses an innovative user-friendly electrochemical approach for the determination of NO over polyaniline (PAni)-based modified electrodes. The electrochemical sensors concocted with PAni, multi-walled carbon nanotubes (CNT), and gum arabic (GA).

The role of size-controlled CeO nanoparticles in enhancing the stability and photocatalytic performance of ZnO in natural sunlight exposure.

In order to enhance the photocatalytic performance and stability, the various proportions of the size controlled cerium oxide (CeO) nanoparticles were dispersed at the pre-synthesized ZnO. Although, the expected dual absorption onsets, probably due to the diminutive difference between the bandgaps of CeO (∼2.9 eV) and ZnO (∼3.
