Hydrogenation of aromatics from low temperature coal tar over novel mesoporous NiMoC/Hβ catalysts
The mesopores Hβ-Tx (x = 1, 2, 3, 4, 5) zeolites were synthesized in different crystallization time (48 h, 72 h, 120 h, 168 h, 240 h), and then the NiMoC/Hβ-Tx catalysts were synthesized by equal volume impregnat...

Improving the visible-light photocatalytic activity of Bi2O4 by the combination of the p–n junction and oxygen vacancy strategy for the degradation of organic pollutants
Constructing p–n heterojunction has been recognized as an effective solution to facilitate the separation of photogenerated carriers through the internal electric field. The introduction of oxygen vacancies (O...

Spatially confined growth of Bi2O4 into hierarchical TiO2 spheres for improved visible light photocatalytic activity
Bi2O4 is a promising visible light responsive photocatalyst but its application is limited by the large particle size and fast recombination rate of charge carriers. Herein, the flower-like hierarchical TiO2 sphe...

Synthesis of Bi2O4@TiO2 Heterojunction with Enhanced Visible Light Photocatalytic Activity
A novel Bi2O4@TiO2 heterojunction was constructed by a simple two-step method. The charges migration between Bi2O4 and TiO2 via the heterojunction improves the electron/hole separation efficiency. Furthermore, Bi
