Single- and few-layer BiOI as promising photocatalysts for solar water splitting

One‐dimensional TiO2 Nanotube Photocatalysts for Solar Water Splitting

Hydrogen production from water splitting by photo/photoelectron-catalytic process is a promising route to solve both fossil fuel depletion and environmental pollution at the same time. Titanium dioxide (TiO2) nanotubes have attracted much interest due to their large specific surface area and highly ordered structure, which has led to promising potential applications in photocatalytic degradatio...

Water Splitting: One‐dimensional TiO2 Nanotube Photocatalysts for Solar Water Splitting (Adv. Sci. 1/2017)

Metal–Organic Frameworks as Promising Photosensitizers for Photoelectrochemical Water Splitting

Ti-based metal-organic frameworks (MOFs) are demonstrated as promising photosensitizers for photoelectrochemical (PEC) water splitting. Photocurrents of TiO2 nano wire photoelectrodes can be improved under visible light through sensitization with aminated Ti-based MOFs. As a host, other sensitizers or catalysts such as Au nanoparticles can be incorporated into the MOF layer thus further improvi...

Single-crystalline, wormlike hematite photoanodes for efficient solar water splitting

A hematite photoanode showing a stable, record-breaking performance of 4.32 mA/cm² photoelectrochemical water oxidation current at 1.23 V vs. RHE under simulated 1-sun (100 mW/cm²) irradiation is reported. This photocurrent corresponds to ca. 34% of the maximum theoretical limit expected for hematite with a band gap of 2.1 V. The photoanode produced stoichiometric hydrogen and oxygen gases in a...

Boosting the Efficiency of Suspended Photocatalysts for Overall Water Splitting.

Water Splitting I is a significant task to cover the residential energy demand of a society (approximately 20% of the total) with solar energy, but it is a much greater challenge to cover all of it, including the demands of industry, commerce, and transportation. The 20% goal may be achievable through photovoltaic-powered households and appliances, but the 100% goal will require extensive facil...
