A novel Type I-like F-scheme heterojunction for improving H₂ generation from water: A case modelled by physically-attached ZnCdS-Cu₂O composite

Main authors: Tsung-Yu Teng, Kim Hoong Ng/MCUT

Type-I heterojunction has been long-perceived non-effective in photocatalytic research. Against such belief, this study demonstrates an improved photocatalytic activity over heterojunction model with Type-I-like band alignment while introducing a new photocatalytic concept associated to ‘F-scheme heterojunction’.

This work offers a potentially sustainable pathway for producing clean fuel using abundant resources such as sunlight and water. By employing semiconductor photocatalysts, solar energy can drive water-splitting reactions without carbon emissions. This technology has strong potential for decentralized hydrogen production, supporting energy storage, fuel cells, and green chemical synthesis. Photocatalytic systems could be integrated into solar farms, buildings, or industrial sites to supply on-demand hydrogen.

Photocatalytically derived hydrogen energy is entirely green in nature. This fits well with the global trend which emphasizing decarbonization and energy security at the same time. Impact wise, green hydrogen can reduce emissions in industry, transport, and power generation, enable large-scale renewable energy storage, and reshape energy trade by lowering dependence on fossil fuels. Investment in hydrogen infrastructure and research positions nations as leaders in clean energy while providing resilient, flexible energy systems that support sustainable development and long-term competitiveness across regions, sectors, policies, markets, communities, supply chains, and future generations worldwide.
