Au@Cu7S4 Yolk@Shell Nanocrystals Set New Hydrogen Production Activity Record under Visible and Near Infrared Irradiation: Assoc. Prof. Tso-Fu Mark CHANG

A significant amount of solar energy that reaches Earth remains unutilized owing to the scarcity of photosensitive materials capable of responding to light in the near infrared (NIR) region. However, this challenge has been addressed by a recent breakthrough from researchers at Tokyo Institute of Technology and National Yang Ming Chiao Tung University. They have developed an innovative Au@Cu7S4 yolk@shell photocatalyst, which is responsive to both visible and NIR wavelengths. This photocatalyst has demonstrated remarkable efficiency in solar hydrogen production, achieving an excellent quantum yield under illumination by both visible and NIR light.
