Scalable Photocatalyst Sheets for Large-Scale Hydrogen Production

Strategic Insights -

Researchers from Xi'an Jiaotong University have made significant progress in developing scalable photocatalyst sheets for large-scale hydrogen production. According to the study, photocatalysis offers a promising solution for converting intermittent solar energy into storable hydrogen fuel. To achieve this, the team successfully immobilized Cd0.7Zn0.3S (CZS) particles on four different substrates, with nonwoven cleanroom wipes (NCWs) exhibiting the highest activity. The optimized photocatalyst sheet, scaled to 50 cm x 100 cm, demonstrated efficient hydrogen generation over a total area of 10 m2 under natural sunlight.
