HOF-Ni-GDY dual-ohmic-junction engineering: inducing photogenerated electron–hole dual channel separation for boosted hydrogen evolution

Key Points

• The aim is to improve hydrogen evolution through enhanced electron-hole separation using Ni and HOF nanorods on GDY.
• Integrated Ni and HOF nanorods onto GDY substrate.
• Utilized acetylene bonds for effective substrate adsorption.
• Explored the role of Ni in electron capture and HOF in microenvironment induction.
• Induced dual-channel separation for photogenerated electrons and holes.
• Achieved improved efficiency in hydrogen evolution reactions with non-noble-metal photocatalysts.
