Direct generation of nitrogen-centered radicals via non-covalent interaction between Cu complexes and BiVO₄ photoanodes.

ABSTRACT: Semiconductor-based photoelectrochemistry commonly relies on efficient interactions between semiconductor surfaces and adsorbates for promoting charge transfer and efficiently activating inert bonds. But at the repulsive interfaces (e.g., between like-charged substrates and electrodes), such interactions cannot be achieved. Contrary to this paradigm, we find that the van der Waals interaction between a series of N-coordinated Cu complex cations and BiVO₄ photoanodes results in a high photovoltage of 0.53 V and charge transfer efficiency of 96%, along with the photocurrent density approaching the theoretical limit of BiVO₄. This non-covalent interaction enables the universal generation of nitrogen-centered radicals from directly cleaving native N-H bonds and generates
