“…CV degradation efficiency using 0.1-Ag 2 O-CAONCS decreases to 78.6%, 82.4% and 75.3% when Mn 2+ , Cu 2+ and Zn 2+ are introduced into CV solution, respectively (supplementary Figure S4). It is obvious that these metallic ions inhibit CV catalytic degradation which is caused by the adsorption of metallic cations on Ag 2 O-CAONCS decreasing reaction active sites [39,40].…”

A photo-deposition method was developed to synthesise argentous oxide/calcium aluminate nanocomposites (Ag2O-CAONCS) with orthorhombic Ca5Al6O14 and cubic Ag2O phases. Micro-morphology, micro-structure, optical, and visible-light catalytic properties were investigated via different techniques. Ag2O enhances visible-light absorption performance and decreases the band gap of the Ag2O-CAONCS. About 20 mL crystal violet (CV) dye (10 mgL–1) is totally degraded using 20 mg Ag2O-CAONCS under sunlight irradiation for 20 min. The enhanced photocatalytic activity of the Ag2O-CAONCS towards CV under sunlight irradiation is ascribed to the reduction of the band gap, improvement in visible-light absorption and inhibitation role of carriers recombination by Ag2O. The high, stable visible-light catalytic activity makes Ag2O-CAONCS promising photocatalysts for removing organic pollutants.

Pyrocatechol is a toxic substance which easily pollutes the environment and Nd vanadate nanowires (NdVONs) were developed for the electrochemical detection of pyrocatechol in the water environment. NdVONs were controllably synthesized via a facile hydrothermal approach using Nd trifluoromethanesulfonate and sodium vanadate. The formation mechanism of the NdVONs was investigated by controlling the synthesis parameters. The obtained nanowires possess single crystalline tetragonal NdVO 4 structure with a length of <10 µm and a diameter of 30-100 nm. There is a well-defined anodic peak at +0.12 V at the NdVON-modified electrode in 0.1 M phosphate buffer saline (PBS) electrolyte containing 1 mM pyrocatechol. The optimized measurement parameters for pyrocatechol detection including a pH value of PBS solution, a deposition time, a deposition potential, and a standing time are pH = 8, 60 s, +1.5 V, and 60 s, respectively. The NdVON-modified electrode indicates broad linear detection range of 0.01-1000 µM, a low limit of detection of 1.15 nM, a reliable stability, reproducibility, selectivity, and a practical application for pyrocatechol detection. The NdVONs are promising for pyrocatechol sensors.

BACKGROUNDCadmium ions may be discarded to the environment with living organisms from fossil fuel combustion, phosphate fertilizer and battery industries. It is urgent and essential to develop a sensitive and rapid method for monitoring Cd2+ level in aquatic environments and biological systems. Neodymium vanadate possesses good catalytic performance for the electrocatalysis of heavy metal ions. Single crystalline Nd vanadate nanoribbons were obtained by a facile approach and used as electrode materials for electrochemical detection of Cd2+.RESULTSThe Nd nanoribbons with tetragonal NdVO4 phase possess length, width and thickness of longer than 10 μm, 200 nm to 1.5 μm and 50 nm, respectively. Nd vanadate nanoribbons can serve as a good electron transfer interface. An anodic peak is located at +0.56 V at the Nd vanadate nanoribbon‐modified electrode in 0.1 mol L−1 KCl electrolyte containing 1 mmol L−1 Cd2+ by square wave voltammetry technique. The Nd vanadate nanoribbon‐modified electrode exhibits a linear range of 0.01–1000 μmol L−1 and a detection limit of 0.29 nmol L−1, with good stability, reproducibility and selectivity for Cd2+ detection.CONCLUSIONThe optimal measurement conditions including the pH value of the KCl solution, deposition time, deposition potential and standing time, which are pH 1, 180 s, −1.0 V and 60 s, respectively. The Nd vanadate nanoribbon‐modified electrode shows great application potential for detecting heavy metal ions in liquid environments. © 2023 Society of Chemical Industry.
