Copper nanoparticles embedded in the triphenylamine functionalized bithiazole–metal complex as active photocatalysts for visible light-driven hydrogen evolution

Abstract

A facile method is developed to prepare Cu NP/Cu–2TPABTz composites, and those nanocomposites were characterized systematically. Amazingly, the resultant nanocomposite 3 has shown enhanced photocatalytic activity (15.38 mmol h⁻¹ g⁻¹) under visible light irradiation, and still maintained 80% of catalytic activity after a long-term stability test (24 h).
