CaF2:Eu2+ transparent ceramics with and without Y3+ doping were fabricated by the hot-pressed sintering method under the inert atmosphere via the co-precipitation-synthesized nanoparticles. After the co-doping of Y3+, there was no significant change in the particle size of the nanoparticles, but the grain size of the ceramics was markedly reduced. The optical transmission of CaF2: Eu2+, Y3+ ceramics at 425 nm achieved approximately 46.3 %, surpassing that of CaF2:Eu2+ ceramics. With Y3+ ions co-doping, the photoluminescence (PL) and X-ray induced emission spectra displayed stronger emission bands at 422 nm ascribed to 5d-4f transitions of Eu2+ ions and weaker emission peaks at 550–650 nm range originating from 4f-4f transitions of Eu3+ ions in Eu2+:CaF2 ceramic. Furthermore, the effect of co-doped Y3+ ions on the scintillation decay lifetime, pulse height spectra, and thermoluminescence of the samples were investigated. © 2025

Slow oxygen evolution reaction (OER) and material transport impedance in catalyst coated membrane (CCM) are major challenges for the practical proton exchange membrane water electrolyzer (PEMWE). Herein, we present a novel OER catalyst with a multilevel porous support and abundant oxygen vacancies to boost efficiency and durability in water electrolysis. The formation of a heterointerface with abundant oxygen vacancies in IrOx improves the catalytic activity and prevents IrOx from peroxidation. Furthermore, the unique pore structure of the support facilitates the mass transport of the anode catalyst layer during water electrolysis at high current density, and the material transport resistance of the water electrolyzer is only 0.0154 Ω cm2 at 1.5 A cm-2. When used in a PEMWE, the prepared electrocatalysts have an impressive electrochemical performance of 1.87 V at 3·A cm-2 with an Ir loading of only 0.91 mg cm-2. This approach highlights the importance of oxygen vacancies and transportation in the catalyst-support interface, providing a promising solution for high-rate practical water electrolysis. © 2023, The Authors.

The challenge of the complex oxygen evolution reaction (OER) currently impedes the efficient production of hydrogen via electrolytic water splitting. To address this issue, the development and improvement of effective electrocatalysts are required. LiCoO2, a key material in lithium-ion batteries, has shown promising potential as an electrocatalyst for electrochemical energy conversion. However, OER catalysts derived from LiCoO2 have faced obstacles such as high overpotential and a complicated preparation process. In this study, the preparation method is adjusted to optimize the synthesis of Li1-xCoO2 with a defective structure, resulting in an impressive overpotential of only 290 mV at a current density of 100 mA cm−2 and a remarkable Tafel slope of 15.2 mV dec−1. The exceptional catalytic activity of Li1-xCoO2 can be attributed to the absence of Li, which triggers oxidative alterations in the electronic structure of Co. Density functional theory (DFT) calculations reveal that Li defects can influence the d-band center of active Co sites, enhancing the adsorption capabilities of Co sites towards *OOH intermediates and increasing the conductivity of the electrocatalyst during the OER process. These alterations improve the velocity of the crucial step in the reaction, ultimately boosting the catalyst's overall performance and efficiency. © 2024 The Authors

Constructing heterojunctions via in-situ growth or mechanical mixing have been widely used for improving the photogenerated carrier separation and photocatalytic activity. However, interface transfer impedance and the charge transfer channels of heterojunction prepared by in-situ method are rarely discussed. In this work, we use tubular g-C3N4 (TCN) as the basic photocatalyst and in-situ growth of nickel/aluminum layered double hydroxide (LDH) nanosheets as co-catalyst on the surface of TCN (TCN@Ni/Al-LDH) to show the advantage of the in-situ constructing heterojunction for highly enhanced photocatalytic hydrogen production. The results show that the TCN@Ni/Al-LDH-60 exhibits the best hydrogen production performance of 1428 μmol h-1 g-1, which is 53.3 and 21.33 times higher than that of TCN and mechanical prepared TCN/Ni/Al-LDH-60. For the first time, we propose a statistics model to reveal that the contact area of the heterojunction TCN@Ni/Al-LDH-60 is 2.88 times that of TCN/Ni/Al-LDH-60. This largely increases the charge transfer channels for the photogenerated carrier transport. In addition, the in-situ growth of TCN@Ni/Al-LDH composites increases the active sites, which improves the utilization efficiency of the photogenerated electrons. This study would shed some light on analyzing the in-situ constructing heterojunction photocatalysts for efficient photocatalytic hydrogen production through photocatalytic water splitting. © 2024, The Authors.
