Z-scheme: Graphitic-C₃N₄/Au/C-TiO₂ hollow spheres are constructed as an all-solid-state Z-scheme photocatalytic system with Au nanoparticles as the electron mediator. The as-synthesized g-C₃N₄/Au/C-TiO₂ photocatalyst showed a remarkably enhanced photocatalytic H₂ evolution rate under visible-light irradiation (λ>420 nm), which was 86 and 42 times higher than those of pure C-TiO₂ and g-C₃N₄, respectively.

g-C3N4 / Au / C-TiO2空心结构的制备，作为可见光驱动的Z型光催化剂，具有增强的H2分解光催化能力

Z方案：将Graphitic-C ₃ N ₄ / Au / C-TiO ₂空心球构建为以Au纳米粒子为电子介体的全固态Z方案光催化体系。合成后的gC ₃ N ₄ / Au / C-TiO ₂光催化剂在可见光照射下（λ > 420 nm）具有显着提高的光催化H ₂析出速率，比纯C-分别高86和42倍。分别为TiO ₂和gC ₃ N ₄。
