Abstract

Read online

Cu2O-based photocathodes for photoelectrochemical water reduction suffer severe self-photo-corrosion issue. Here the authors report an in-situ encapsulation strategy with hydrogen-substituted graphdiyne to protect Cu2O for water reduction with a photocurrent density of −12.88 mA cm-2.
