Even though the well-established Haber-Bosch process has been major artificial way to "fertilize" earth, its energy-intensive nature motivating people learn from nitrogenase, which can fix atmospheric N2 NH3 in vivo under mild conditions with precisely arranged proteins. Here we demonstrate that efficient fixation of proceed room temperature and pressure water using visible light illuminated BiOBr nanosheets oxygen vacancies absence any organic scavengers precious-metal cocatalysts. The...
Incorporating carbon into Bi3O4Cl enhances its internal electric field by 126 times, which induces a bulk charge separation efficiency (ηbulk) of 80%. This ultrahigh ηbulk value presents state-of-the-art result in tuning the separation. The generated C-doped has noble-metal- and electron-scavenger-free water-oxidation ability under visible light, is difficult to achieve with most existing photocatalysts. As service our authors readers, this journal provides supporting information supplied...
Understanding the chemistry of hydrogen peroxide (H2O2) decomposition and hydroxyl radical (•OH) transformation on surface molecular level is a great challenge for application heterogeneous Fenton system in fields chemistry, environmental, life science.

By controlling delicate structure catalyst, novel allows facile...
A central issue in understanding photocatalytic water splitting on a stoichiometric or defective nanostructured oxide surface is its adsorption mode and related reactivity. More than just improving the of surfaces, we demonstrate this work that oxygen vacancies (OVs) also offer possibility activating toward thermodynamically enhanced oxidation, while activation state, as reflected by capability to trap holes, strongly depends structures OVs. Utilizing well-ordered BiOCl single-crystalline...

These metallic endow mechanical flexibility, reduce local current...
A novel Cu2O/TiO2 composite photocatalyst structure of Cu2O nanospheres decorated with TiO2 nanoislands were synthesized by a facile hydrolyzation reaction followed solvent-thermal process. In this photocatalyst, served as the main visible light absorber, while formed heterojunctions good contact Cu2O, beneficial to photoexcited electron transfer between them. Their band match and inner electrostatic field from p–n heterojunction both favored electrons TiO2, which effectively separated...
Electrochemical ammonia (NH3) synthesis from nitrate (NO3-) reduction offers an intriguing approach for both sustainable and environmental denitrification, yet it remains hindered by a complicated reaction pathway with various intermediates. Here we present that the interlayer strain compression in bismuth (Bi) nanocrystals can contribute to activity selectivity improvement toward NH3 electrosynthesis NO3- reduction. By virtue of comprehensive spectroscopic studies theoretical calculations,...
Prussian blue analogs (PBAs) are promising catalysts for green hydrogen production. However, the rational design of high-performing PBAs is challenging, which requires an in-depth understanding catalytic mechanism.
