Synergistic CNT‐Integrated Ni‐Phthalocyanine/g‐C3N4 Heterojunctional Photocatalysts With Single Ni–N4 (II) Sites for Efficient Ammonia Synthesis

open access: yesElectron, EarlyView.
We present a tandem nickel phthalocyanine (NiPc)/CNT‐P&Cu‐BCN photocatalyst, engineered with an organic–organic heterojunction for enhanced nitrogen conversion. This system integrates boron‐doped (B) nitrogen‐deficient (N) carbon nitride (CN), modified via Cu–Cu coordination and phosphorus doping through sodium borohydride‐assisted thermal treatment ...
