PdRuO/PVP nanomaterial as a highly selective, stable, and applicable potentiometric sensor for the detection of Cr.

PdRuO/PVP nanomaterial was synthesized using a straightforward method and characterized using advanced analytical methods such as TEM, XRD, XPS, elemental mapping and SEM. The synthesized PdRuO/PVP nanomaterial was used as an ionophore in potentiometric sensor electrodes and successfully adapted to Cr ion detection in a large number of aqueous samples. Several experimental parameters of the PdRuO/PVP sensor such as potentiometric behavior, selectivity, repeatability, response time, pH, titration, and recovery in real samples were investigated.

In situ preparation of TiO/f-MWCNT catalyst using Pluronic F127 assisted sol-gel process for sonocatalytic degradation of methylene blue.

In this study, titanium dioxide- Pluronics @F127/functionalized -multi walled carbon nanotubes (TiO-F127f-/MWCNT) nanocatalysts were prepared, characterized, and used in methylene blue (MB) degradation under ultrasonic conditions. The characterization studies were performed using TEM, SEM, and XRD analyses to reveal the morphological and chemical properties of TiO-F127/MWCNT nanocatalysts. To detect the optimum parameters for MB degradation using TiO-F127/f-MWCNT nanocatalysts, several experimental parameters were conducted at various conditions such as different temperatures, pH, catalyst amount, hydrogen peroxide (HO) concentration, and various reaction contents.
