要旨

In this communication, we report an innovative electrode design of 3D hierachical TiO2 urchin assembled with a hollow TiO2 spheres core and radial TiO2 nanorod shell prepared via a facile colloid template route combined with atomic layer deposition and a hydrothermal growth process. The periodically hierarchical TiO2 urchin exhibits excellent omnidirectional anti-reflectance properties in a wide range of wavelengths and angles of incidence (AOI). When tested as a photoanode for PEC water splitting, a greatly improved photoelectrochemical water splitting performance is obtained in comparison to that of TiO2 microspheres due to the improved light harvesting and charge collection efficiency.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
