A g-C3N4@Au@SrAl2O4:Eu2+,Dy3+composite as an efficient plasmonic photocatalyst for round-the-clock environmental purification and hydrogen evolution

Here, we demonstrate a g-C₃N₄@Au@SrAl₂O₄:Eu²⁺,Dy³⁺composite as a novel efficient self-luminous visible-light plasmonic photocatalyst for photocatalytic degradation of organic pollutants and hydrogen evolution from water around the clock.
