报告题目:SIn2Te/TeIn2Se: a type-II heterojunction as water-splitting photocatalyst with high solar energy harvesting

报告摘要: Searching for photocatalyst is crucial for the production of renewable hydrogen from water. The major limiting factors affecting the efficiency of solar fuel synthesis include; (i) light absorption, (ii) charge separation and transport and (iii) surface chemical reaction. The loading of secondary semiconductors that can act as either electron or hole acceptors for improved charge separation is a promising strategy, leading to the adaptation of a junction architecture. Using first-principles calculations within the HSE06 functional, we propose the type-II semiconductor heterojunction SIn₂Te/TeIn₂Se as a promising solar-driven water-splitting photocatalyst which could simultaneously overcome major limiting factors of solar fuel synthesis.
