Enhanced photocatalytic reduction of Cr(<scp>vi</scp>) to Cr(<scp>iii</scp>) over g-C₃N₄ catalysts with Ag nanoclusters in conjunction with Cr(<scp>iii</scp>) quantification based on <i>operando</i> low-field NMR relaxometry

Abstract

Ag nanoclusters are anchored on g-C₃N₄ for the photocatalytic reduction of Cr(<sc>vi</sc>), and experience real-time monitoring by <italic>operando</italic> low-field NMR relaxometry <italic>via</italic> quantifying the concentration of paramagnetic Cr(<sc>iii</sc>) in solution.
