Rationally construction of atomic-precise interfacial charge transfer channel and strong build-in electric field in nanocluster-based Z-scheme heterojunctions with enhanced photocatalytic hydrogen production

The lack of effective charge transfer driving force and channel limits the electron directional migration in nanoclusters (NC)-based heterostructures, resulting in poor photocatalytic performance. Herein, a Z-scheme NC-based heterojunction (Pt1Ag28-BTT/CoP, BTT = 1,3,5-benzenetrithiol) with strong internal electric field is constructed via interfacial Co–S bond, which exhibits an absolutely superiority in photocatalytic performance with 24.89 mmol·h−1·g−1 H2 production rate, 25.77
