Although molybdenum disulfide (MoS_(2))-based materials are generally known as active electrocatalysts for the hydrogen evolution reaction (HER), the inert performance for the oxygen evolution reaction (OER) seriously limits their wide applications in alkaline electrolyzers due to there exists too strong metal-sulfur (M−S) bond in MoS_(2). Herein, by means of surface reorganization engineering of bimetal Al, Co-doped MoS_(2) (devoted as AlCo_(3)-MoS_(2)) through in situ substituting partial oxidation, we successfully significantly activate the OER activity of MoS_(2), which affords a considerably low overpotential of 323 mV at −30 mA cm^(−2), far lower than those of MoS_(2), Al-MoS_(2) and Co-MoS_(2) catalysts. Essentially, the AlCo_(3)-MoS_(2) substrate produces lots of M−O (M=Al, Co and Mo) species with oxygen vacancies, which trigger the surface self-reconstruction of pre-catalysts and simultaneously boost the electrocatalytic OER activity. Moreover, benefiting from the moderate M−O species formed on the surface, the redistribution of surface electron states is induced, thus optimizing the adsorption of OH* and OOH* intermediates on metal oxyhydroxides and awakening the OER activity of MoS_(2).

Electrochemical nitrate reduction to ammonia(NRA) can realize the green synthesis of ammonia(NH3) at ambient conditions, and also remove nitrate contamination in water. However, the current catalysts for NRA still face relatively low NH3yield rate and poor stability. We present here a core-shell heterostructure comprising cobalt oxide anchored on copper oxide nanowire arrays(CuO NWAs@Co_(3)O_(4)) for efficient NRA. The CuO NWAs@Co_(3)O_(4)demonstrates significantly enhanced NRA performance in alkaline media in comparison with plain CuO NWAs and Co_(3)O_(4)flocs. Especially, at-0.23 V vs. RHE, NH_(3) yield rate of the CuO NWAs@Co_(3)O_(4)reaches 1.915 mmol h^(-1)cm^(-2),much higher than those of CuO NWAs(1.472 mmol h^(-1)cm^(-2)), Co_(3)O_(4)flocs(1.222 mmol h^(-1)cm^(-2)) and recent reported Cu-based *** is proposed that the synergetic effects of the heterostructure combing atom hydrogen adsorption and nitrate reduction lead to the enhanced NRA performance.

High-power phosphor-converted laser lighting and laser display have gained significant attention due to their superior energy efficiency and long lifespan. However, the elevated operating temperatures under high-power excitation induce severe thermal quenching of phosphor materials, compromising the thermal stability and emission performance. To address this issue, we proposed a multi-component co-doping strategy by incorporating Ba2+/Si4+ and Sr2+/Si4+ into Ce: YAG phosphor ceramics. The optimized Sr05Ba050 sample demonstrated exceptional thermal stability, retaining 96.56% of its emission intensity at 423 K. Moreover, the thermal saturation threshold increased to 73 W/mm2, significantly surpassing that of undoped Ce: YAG. This improvement is attributed to a combination of lattice stabilization and reduced electron-phonon coupling induced by the co-doping approach. Additionally, the optimized sample achieved a luminous efficiency of radiation (LER) of 248.82 lm/W and exhibited a lower surface temperature under high-power excitation. These findings highlight the effectiveness of Ba2+/Si4+ and Sr2+/Si4+ co-doping in mitigating thermal quenching and enhancing high-temperature performance, providing valuable insights for next-generation high-power lighting and display applications. © 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.
