Biochar as an adsorbent is paid more attention for treating uranium-containing wastewater. In this work, a novel microalgae-derived biochar(A-HTC) was synthesized by dual-template one-step carbonization for uranium adsorption. This biochar exhibited a maximum adsorption capacity of 472.3 mg·g−1. Especially, A-HTC demonstrated excellent selectivity for uranium over 11 competing cations and remarkable reusability after 10 adsorption-desorption cycles. The adsorption behavior with time and uranium concentration followed the pseudo-second-order kinetic model and the Langmuir isotherm model, respectively. Moreover, the adsorption process was spontaneous and endothermic. Zeta potential, XPS, and FTIR analyses revealed that A-HTC adsorbs U(VI) mainly through electrostatic attraction and complexation. The present study offers an innovative adsorbent and a novel method to produce biochar for uranium recovery from aquatic environments. © 2025 The Korean Society of Industrial and Engineering Chemistry

In this study, a novel Sm3+-doped phosphor was synthesized via the high-temperature solid-state reaction, and its properties were systematically characterized. The unit co-substitution strategy was adopted for structural design. Comprehensive structural analysis, including X-ray diffraction (XRD) and Rietveld refinement, confirmed the formation of a stable crystal structure with the successful incorporation of Sm3+ ions. Elemental mapping demonstrated a uniform distribution of elements across the sample. Photoluminescence (PL) studies demonstrated strong orange-red emission under near-ultraviolet excitation, with the main emission peak at 617 nm. At the optimal doping concentration of x = 0.04, the emission intensity reaches its maximum, while higher concentrations result in concentration quenching, which is attributed to dipole-dipole interactions. Additionally, an increase in Sm3+ concentration resulted in a reduction in fluorescence lifetimes. Thermal stability analysis demonstrated that the Ca2GdGa3Ge2O12:Sm3+ garnet phosphor retained 79 % of its initial emission intensity at 398 K, showcasing excellent anti-thermal quenching performance. Additionally, with a quantum efficiency of 22.52 %, the phosphor exhibits promising potential for practical LED applications. This potential was further confirmed by the fabricated white light-emitting diode (LED) device, combining the Ca2GdGa3Ge2O12:Sm3+ phosphor with commercial blue and green phosphors, achieved a high color rendering index (CRI) of 93.2, a correlated color temperature (CCT) of 6156 K. © 2025 Elsevier Ltd and Techna Group S.r.l.
