Development of visible light-responsive organo-photocatalysis devices for oxidative decomposition of ammonia

以无碳氨水和联氨为原料制备分子氢为目标，开发了可见光响应型光催化装置。与传统的无机半导体方法不同，设计并制备了有机p/n双层膜的光催化体系，通过该体系成功地证实了肼的化学计量比分解导致了整个可见光区域内分子氢的形成。此外，我们还展示了氨在有机p/n双层膜上的氧化活化的新例子，特别是对于分子氢的形成。

Development of visible light-responsive photocatalysis devices was conducted to aim at producing molecular hydrogen from carbon-free ammonia and hydrazine. Different from conventional approaches by means of inorganic semiconductors, a photocatalysis system of an organic p/n bilayer was designed and fabricated, through which stoichiometric decomposition of hydrazine was successfully confirmed to result in the formation of molecular hydrogen over the entire visible light region. Furthermore, we also exhibited the novel example of the oxidative activation of ammonia at an organic p/n bilayer coated with a cocatalyst, particularly for molecular hydrogen formation.
