摘要:
Stable metal nitrides (MN) are promising materials to fit the future "green" ammonia-hydrogen nexus. Either through catalysis or chemical looping, the reductive hydrogenation of MN to MN(1-x) is a necessary step to generate ammonia. However, encumbered by the formation of kinetically stable M-NH(1─3) surface species, this reduction step remains challenging under mild conditions. Herein, we discovered that deleterious Ti-NH(1─3) accumulation on TiN can be circumvented photochemically with supported single atoms and clusters of platinum (Pt(1)-...
