Abstract：

As　a　crystalline　allotrope　of　carbon　nitrides,　poly　(heptazine　imide)　(PHI)　exhibits　great　potential　for　photocatalytic　reforming　of　biomass-derived　alcohols.　However,　its　activity　is　greatly　constrained　due　to　insufficient　charge　migration　and　severe　non-radiative　recombination.　To　address　this　issue,　PHI　with　high　interlayer　stacking　orderliness　is　fabricated　through　a　facile　ion　exchange　strategy.　Characterizations　reveal　that　rational　modification　of　the　interlayer　stacking　mode　of　PHI　could　efficiently　suppress　non-radiative　recombination　and　improve　charge　transfer　efficiency.　Accordingly,　the　optimal　sample　exhibits　high　photocatalytic　reforming　activity　for　H2　evolution,　which　is　up　to　2.16　mmol·g−1·h−1,　and　with　a　quantum　efficiency　reaches　26.7%　at　400 nm.　©　2025　Wiley-VCH　GmbH.
