Spherical shape-defined hollow UiO-66 metal-organic frameworks with superior incident photon scattering for enhanced photoelectrochemical H evolution.

Herein, spherical hollow N-doped carbon-incorporated UiO-66 metal-organic frameworks (MOF, H-UiO-66) are synthesized using bio-inspired polydopamine (pDA) nanoparticles as multifunctional starting templates. The calculated band properties (E = -0.45 eV and E = 2.

Yolk-shell ZnO@C-CeO ternary heterostructures with conductive N-doped carbon mediated electron transfer for highly efficient water splitting.

Herein, carbon-incorporated yolk-shell ZnO@C-CeO ternary heterostructures are employed as visible light responsive photocatalyst for highly efficient photoelectrochemical (PEC) water splitting. Compared to conventional ZnO/CeO semiconductors, introduction of a thin PDA shell layer assures the generation of a conductive N-doped graphitic carbon layer after a calcination post-treatment with mesoporous hollow morphologies. The evaluation of PEC water splitting performance of ZnO@C-CeO photoanodes reveals the maximum photocurrent density as 7.
