Summary: A La-BiOCl/layered double hydroxide (LDH) composite photocatalyst was synthesized using a hydrothermal method. The catalyst showed improved photocatalytic performance for tetracycline (TC) hydrochloride degradation, with a removal rate of 79.8% within 2 hours under visible light irradiation. The material exhibited a larger surface area, increased optical absorption threshold, and narrower bandgap width compared to pure BiOCl. The photocatalytic degradation process followed a first-order kinetic model.

Summary: In this study, a copper and bismuth co-doped CeO2 nanostructure was synthesized using subcritical hydrothermal method for water remediation application. The co-doping of copper and bismuth synergistically improved the conductivity and light-harvesting capabilities of the co-doped CeO2, as confirmed through current-voltage and optical studies. The microstructural, compositional, and morphological information of the photocatalyst were analyzed using powder XRD and spectroscopic techniques. The as-prepared co-doped CeO2-based photocatalyst demonstrated efficient mineralization of the anionic dye methyl orange under solar irradiation, outperforming a CeO2 photocatalyst in terms of effectiveness and rate of dye mineralization. The co-doped CeO2 photocatalyst also exhibited excellent robustness and retained its photocatalytic activity after multiple reusability tests.

Summary: Dopamine (DA) disorder is associated with various neuronal dysfunctions, making DA homeostasis crucial for neuronal health and physiological condition. However, developing molecular probes for in vitro screening of DA with spatiotemporal resolution is a challenge. In this study, we propose a novel material, La2O3@Fe2O3/PPy, which exhibits enhanced electrocatalytic activity for DA oxidation and selective DA sensing with a detection limit of 1.2 nM. Furthermore, this transducing interface effectively detects dopamine from lacrimal fluid with good recoveries, making it a promising tool for in vitro analysis of DA from real samples.

Summary: A perovskite-based photoelectrochemical system was developed for the degradation of organic pollutants in wastewater. La3+-doped BFO photoanodes showed enhanced performance, with the best electrode exhibiting a three times higher current response than pure BFO. The improvements in electrode performance were attributed to the synergistic effect of applied bias potential and the introduction of La3+ into the BFO matrix.

Summary: In this study, novel nanorod-like lanthanum-bismuth (La-Bi) mixed oxides were designed as catalysts for the catalytic hydrolysis of carbonyl sulfide (COS). The Bi-doped catalyst showed significantly improved COS hydrolysis activity compared to bare La oxide. The catalysts were analyzed comprehensively to understand their structural and chemical properties, and it was found that Bi doping enhanced the catalyst's basicity and electron transfer, leading to improved hydrolysis activity. Furthermore, the La-Bi mixed oxide catalyst exhibited excellent sulfur tolerance and stability in long-term testing using simulated industrial gas.

Summary: The Fe-doped and Fe/N-co-doped graphene composite materials were synthesized from a graphene oxide dispersion using a hydrothermal method. The Fe2+ was oxidized to alpha-Fe2O3, while the graphene oxide was reduced to rGO during the reaction. In the Fe/N co-doped material, nitrogen atoms were incorporated into the graphene structures in the form of C-N and C=N bonds, leading to improved conductivity and kinetics for ion and electron transport.

Summary: Ultra-rapid microwave-assisted hydrothermal synthesis of zinc oxide nanoparticles doped with gallium was performed. The synthesis time and Ga doping facilitated the production of ZnO nanoparticles with nanorods morphology and improved properties. The successful insertion of Ga into the ZnO lattice was confirmed, and the presence of defects as a result of doping was observed. The band gap range found in the doped ZnO nanoparticles increased their potential for optical applications.
