A Cu20 Cluster-Based Moisture-Absorbent Composite Membrane for Efficient Photocatalytic Hydrogen Evolution in Seawater under Non-Contact Configuration

Key Points

• The aim is to evaluate a Cu20 cluster-based membrane for its effectiveness in photocatalytic hydrogen production from seawater.
• Developed a moisture-absorbent composite membrane with Cu20 clusters.
• Experimented with photocatalytic hydrogen evolution under non-contact conditions.
• Assessed the impact of salt ions on hydrogen production efficiency.
• The Cu20 composite membrane showed significant enhancement in hydrogen production in seawater environments.
• Salt ions negatively affected the photocatalytic activity, but the composite mitigated some of these effects.
• The membrane maintained stable performance over multiple cycles.
