Competitive Coordination‐Oriented Monodispersed Ruthenium Sites in Conductive MOF/LDH Hetero‐Nanotree Catalysts for Efficient Overall Water Splitting in Alkaline Media

Abstract Rational exploration of efficient, inexpensive, and robust electrocatalysts is critical for the efficient water splitting. Conjugated conductive metal–organic frameworks (cMOFs) with multicomponent layered double hydroxides (LDHs) to construct bifunctional heterostructure catalysts are considered as an efficient but complicated strategy. Here, the fabrication of a cMOF/LDH hetero‐nanotree array catalyst (CoNiRu‐NT) coupled with monodispersed ruthenium (Ru) sites via a controllable grafted‐growth strategy is reported. Rich‐amino hexaiminotriphenylene linkers coordinate with the LDH nanotrunk to form cMOF nanobranches, providing numerous anchoring sites to precisely confine and stabilize RuN 4 sites.…
