It is highly desired to synthesize low‐cost photocatalysts for the degradation of colored dyes to safeguard our environment for the future generations. Here, we report an extremely efficient and low‐cost synthesis of alkaline earth and transition‐metal ferrite photocatalysts (MgFe2O4, CaFe2O4, BaFe12O19, CuFe2O4, and ZnFe2O4) from their chloride salts and their applications for the degradation of methylene blue (MB) dye under UV–visible and direct sunlight irradiation. The as‐prepared photocatalysts displayed enhanced photoactivities under both conditions of irradiation. After calcination at 600°C, the photocatalytic degradation increased significantly, and 96 and 85% MB was removed with ZnFe2O4 under UV–visible and direct sunlight irradiation, respectively. Moreover, large amounts of hydroxyl free radicals were produced under both irradiation conditions, which participated in the degradation of MB. The enhanced photodegradation activities of these photocatalysts are attributed to their extended visible light absorption and low bandgaps. This work will provide a feasible route to the synthesis of efficient and low‐cost photocatalysts to utilize sunlight for environmental remediation.

“…In this view, an enormous analytical tool has been developed for the qualitative and quantitative analysis of H 2 O 2 and glucose including chromatography, 7 spectrometry, 8 fluorescence, 9 colorimetry, 10 and so on. Nevertheless, most of these developed assays are highly expensive and include tedious and laborious procedure due to their lengthy assay times that always needed an expert operator to handle the complicated analytical procedures and usage of toxic reagents.…”

Herein, a hierarchical structure of flower-like NiCo layered double hydroxides (NiCo LDH) microspheres composed of three-dimensional (3D) ultrathin nanosheets was successfully synthesized via a facile hydrothermal approach. The formation of NiCo LDH was confirmed by various physicochemical studies, and the NiCo LDH-modified glassy carbon electrode was used as an efficient dual-functional electrocatalyst for non-enzymatic glucose and hydrogen peroxide (H2O2) biosensor. The host matrix of hydrotalcite NiCo LDH exhibits the enhanced electrocatalytic sensing performances with a quick response time (<3 s), wide linear range (50 nM–18.95 mM and 20 nM–11.5 mM) and lowest detection limits (S/N = 3) (10.6 and 4.4 nM) toward glucose and H2O2, and also it exhibits good stability, selectivity, and reproducibility. In addition, this biosensor was successfully utilized to the real-time detection of endogenous H2O2 produced from live cells and glucose in various biological fluids, and demonstrates that the as synthesized NiCo LDH may provide a successful pathway for physiological and clinical pathological diagnosis.

“…It is clear from Figure 4A that g-C 3 N 4 gives intense peak at 470 nm, indicating poor charge separation. However, the intensities of the composites are progressively decreased as the amount of SnO 2 nanoparticles is increased, and the optimized sample shows relatively low PL peak, indicating excellent charge separation in it Ali et al, 2016;Lu et al, 2018;Ali N. et al, 2019;Ali S. et al, 2019). The relatively low intensities of PL peaks indicate enhanced charge separation and are responsible for improved photoactivities.…”

Energy crises and environmental pollution are two serious threats to modern society. To overcome these problems, graphitic carbon nitride (g-C 3 N 4 ) nanosheets were fabricated and functionalized with SnO 2 nanoparticles to produce H 2 from water splitting and degrade 2-chlorophenol under visible light irradiation. The fabricated samples showed enhanced photocatalytic activities for both H 2 evolution and pollutant degradation as compared to bare g-C 3 N 4 and SnO 2 . These enhanced photoactivities are attributed to the fast charge separation as the excited electrons transfer from g-C 3 N 4 to the conduction band of SnO 2 . This enhanced charge separation has been confirmed by the photoluminescence spectra, steady state surface photovoltage spectroscopic measurement, and formed hydroxyl radicals. It is believed that this work will provide a feasible route to synthesize photocatalysts for improved energy production and environmental purification.
