Efficient Charge Separation and Transport in Fullerene-CuPcOC<sub<8</sub< Donor–Acceptor Nanorod Enhancing Photocatalytic Hydrogen Generation
Photocatalytic hydrogen generation via water decomposition is a promising avenue in the pursuit of large-scale, cost-effective renewable hydrogen energy generation. However, the design of an efficient photocatalyst plays a crucial role in achieving high yields in hydrogen generation. Herein, we have engineered a fullerene-2,3,9,10,16,17,23,24-octa(octyloxy)copper phthalocyanine (C<sub<60</sub<-CuPcOC<sub<8</sub<) photocatalyst, achieving both efficient hydrogen generation and high stability. The significant donor–acceptor (D–A) interactions facilitate the efficient electron transfer from CuPcOC<sub<8</sub< to C<sub<60</sub<. The rate of photocatalytic hydrogen generation for C<sub<60</sub<-CuPcOC<sub<8</sub< is 8.32 mmol·g<sup<−1</sup<·h<sup<−1</sup<, which is two orders of magnitude higher than the individual C<sub<60</sub< and CuPcOC<sub<8</sub<. The remarkable increase in hydrogen generation activity can be attributed to the development of a robust internal electric field within the C<sub<60</sub<-CuPcOC<sub<8</sub< assembly. It is 16.68 times higher than that of the pure CuPcOC<sub<8</sub<. The strong internal electric field facilitates the rapid separation within 0.6 ps, enabling photogenerated charge transfer efficiently. Notably, the hydrogen generation efficiency of C<sub<60</sub<-CuPcOC<sub<8</sub< remains above 95%, even after 10 h, showing its exceptional photocatalytic stability. This study provides critical insight into advancing the field of photocatalysis..
