Facile synthesis of hierarchical CdS nanoflowers for efficient piezocatalytic hydrogen evolution.

Piezocatalytic hydrogen evolution has emerged as a promising field for the collection and utilization of mechanical energy, as well as for generating sustainable energy throughout the day. Hexagonal CdS, an established semiconductor photocatalyst, has been widely investigated for its ability to split water into H. However, its piezocatalytic performance has received less attention, and the relationship between its structure and piezocatalytic activity remains unclear.

Immobilization of g-CN nanosheets on diatomite electrostatic adsorption and their photocatalytic activity.

Graphitic carbon nitride (g-CN) nanosheets have been successfully immobilized on diatomite to form a g-CN/diatomite hybrid through a facile electrostatic adsorption method and subsequent calcination process. Electron microscopy studies confirm that the surface of the diatomite is tightly covered with g-CN nanosheets. In addition, the characterization results of Fourier transform infrared spectra (FTIR) and X-ray photoelectron spectra (XPS) verify that there is a strong interaction between the g-CN and diatomite components inside the hybrids.
