In situ controllably self-assembled amorphous Co–TDPAT MOFs as superior cocatalysts of α-Fe 2 O 3 nanosheet arrays for highly efficient and ultrastable photoelectrochemical oxygen evolution

An α-Fe 2 O 3 NSA in situ self-assembled with an ultrathin, conformal amorphous Co–TDPAT MOF shows record-high activity and stability toward PEC oxygen evolution.
