A Visible-light-responsive Photocatalyst of Nitrogen-doped Solid-acid HNb3O8-N Studied by Ultrahigh-field 1H MAS NMR and 1H–93Nb/1H–15N HETCOR NMR in Solids
A visible-light-responsive nitrogen-doped solid-acid photocatalyst HNb3O8-N is investigated via solid-state high-resolution NMR spectroscopy. The 1H magic-angle-spinning (MAS) spectrum observed und...
