Constructing 3D hierarchical TiO microspheres with enhanced mass diffusion for efficient glucose photoreforming under modulated reaction conditions.

Three-dimensional (3D) TiO hierarchical microspheres (THMs) were successfully prepared via a facial template-free hydrothermal approach. The possible growth mechanism of THM was also investigated by TiCl concentration-, time-, and temperature-dependent experiments. The results indicate that the formation of an urchin-like hierarchical structure may follow a "nucleation-dissolution and recrystallization-assembly" process.

Effective enhancement of electron migration and photocatalytic performance of nitrogen-rich carbon nitride by constructing fungal carbon dot/molybdenum disulfide cocatalytic system.

To find a cocatalyst that can replace noble metals, fungal carbon dot (CD) modified molybdenum disulfide (MoS) cocatalyst system was designed. The composites were prepared by hydrothermal and calcination methods with different ratios of CDs, MoS and nitrogen-rich carbon nitride (p-CN). p-CN has excellent electronic properties, and MoS modified by CDs (D-MoS) can significantly enhance the photocatalytic performance of p-CN by improving the photogenerated electron migration efficiency.

Biomimetic nitrogen-rich photocatalyst based on cadmium sulfide for photocatalytic hydrogen evolution.

A novel N-rich sugarcane-like photocatalyst CdS/CN (CCN) was prepared by a thermal polymerization method and tested for generating H and realizing antiphotocorrosive performance. The best photocatalytic H evolution is obtained for a CdS to CN mass ratio of 1:1 (CCN3), which is nearly 33 and 3 times higher than that of pure CN and CdS, respectively. CCN3 can be used to effectively reduce CdS photocorrosion and increase stability because of its N-rich performance and sugarcane-like structure, which can affect electron transport and enhance the internal binding force, respectively.
