Summary: Introducing smaller Mg2+ ions to replace Ca2+ site in the BaLaCaSbO6 matrix leads to a significant enhancement in luminescence intensity, red-shift, and luminescence lifetime. These modulations are mainly attributed to the strengthen pressure on the local structure, superior lattice rigidity, and suppression of non-radiative transition after the substitution of smaller Mg2+. The effective lifetime-based luminescence thermometry is achieved due to thermal quenching behavior of Mn4+ ions in the matrix.

Summary: The Mn4+, Dy3+ co-doped La2MgTiO6 phosphors were synthesized using the high-temperature solid-phase method. The crystal phase luminescence properties, X-ray photoelectron spectroscopy (XPS), and thermal quenching were analyzed. The phosphors exhibited two emission peaks, one due to the energy level jump of Dy3+ ion and the other due to the energy jump of Mn4+. The influence of Mn4+, Dy3+ on temperature was different, and the maximum relative sensitivity was 2.85% K-1 in the range of 298-498 K. These results indicate the potential applications of La2MgTiO6: Mn4+, Dy3+ phosphors in optical thermometry.

Summary: Changing the Ga:Al ratio modulates the energy gap and modifies the spectroscopic properties of the phosphors. The stabilization of the Gd3Ga5O12 garnet structure by Al3+ ions widens the energy gap. Increasing Ga content leads to a decrease in the energy gap, affecting the interaction between oxygen ligands and luminescent ions.

Summary: This paper proposes a strategy to regulate the non-metal atom sulfur and oxyphilic transition metal atom iron to optimize the alkaline hydrogen evolution reaction and oxygen evolution reaction performance of metallic nickel. The results show that this regulation method can significantly enhance the activity of nickel catalyst, enabling it to achieve high current density at lower overpotential. Experimental results demonstrate that the sulfur and iron regulation can optimize the adsorption of hydrogen and water, thereby improving the performance of the hydrogen evolution reaction, and the derived sulfur-doped NiFe hydroxyl oxide enhances the performance of the oxygen evolution reaction.

Summary: In this work, a multicomponent transition metal catalyst Cr-Cu/CoOx was loaded on copper foam by electrodeposition and annealing, and exhibited excellent electrochemical activity. The HER overpotential is 21 mV and the OER overpotential is 252 mV at a current density of 10 mA cm-2. The overall water splitting voltage is 1.51 V, even better than the Pt/C//RuO2 two-electrode system (1.61 V). The excellent performance of this catalyst is mainly derived from the synergistic interaction among Cu, Co, and Cr.

Summary: Highly durable and active PtCuCo nanoframes were prepared as enhanced bifunctional electrocatalysts for oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR) in acidic environment. The PtCuCo nanoframes exhibited remarkable activity and durability due to their ternary compositions and structure-fortifying frame structures. The specific/mass activity of PtCuCo nanoframes for ORR in perchloric acid solution was 12.8/7.5 times as large as that of commercial Pt/C, while for MOR in sulfuric acid solution, the mass/specific activity was 5.4/9.4 times as large as that of Pt/C. This work may provide a promising nanoframe material for developing dual catalysts for fuel cells.

Summary: Ammonia borane (AB, NH3BH3) is a promising hydrogen storage material due to its high hydrogen content, low molecular weight, high solubility, high stability, and non-toxicity. However, the slow rate of hydrogen release from AB in pure water has led to research on catalysts. Metal oxides have shown potential as catalysts for the hydrolysis of AB, but oxidation and agglomeration of transition metals hinder their activity and stability. This review summarizes the research progress on metal oxide-based catalysts, discussing their preparation methods, compositional structures, performance optimization, hydrolysis mechanisms, and future prospects.

Summary: A copper modified sulfur doped Co(OH)2 hybrid catalyst (Cu@S-Co(OH)2) was prepared and showed efficient hydrogen evolution reaction (HER) activity with ultralow overpotential of 42 mV at a current density of 10 mA cm 2. The active center was identified as cobalt metal, and both sulfur and copper enhanced the adsorption of OH species while sulfur contributed to the adsorption of H and copper promoted the desorption of H. This study provides a facile method and new insight to enhance the HER activity for transition metal hydroxides via metal and non-metallic elements co-modulation.
