Summary: This study successfully achieved high visible-light photocatalytic performance by preparing ultrathin (1.5-2.5 nm) (002) faceted CdS nanobelts, which resulted in high apparent quantum yield and photocatalytic hydrogen production rate. The controllable thickness of the CdS nanobelts led to an ideal value of hydrogen adsorption free energy, contributing to the enhanced photocatalytic performance.

Summary: In this study, TiO2/CdS nanocomposites with different exposed facets were synthesized and characterized. Among them, FMA-TiO2/CdS exhibited the highest photocatalytic activity with a degradation efficiency of 88.4%, attributed to its largest surface energy, co-exposed {101}/{010} facets, lowest photoluminescence intensity, lower charge-transfer resistance, and higher charge-transfer efficiency.

Summary: In this paper, khaki titanium dioxide (TiO2) crystals with different morphologies and specific exposed crystal facets were prepared for the first time by using a TiCl3 treatment process in the presence and absence of morphology-controlling agents. The synthesized TiO2 crystals showed enhanced photocatalytic activity due to the combined effect of the anatase phase structure, relatively larger specific surface area, and the effective separation of the photogenerated electron-holes.

Summary: The activities for H-2 evolution in semiconductor-based photocatalysts are influenced by their morphologies and exposed facets. This study reveals that CdS with the (002) crystal facet and a small capacitance plays a vital role in enhancing photocatalytic H-2 evolution. The findings suggest that efficient semiconductor-based photocatalysts can be designed by focusing on CdS with the (002) facet and a small capacitance.

Summary: The research showed that the crystal facet {? 111} of 8-MnO2 significantly enhanced the oxidative degradation activity towards organic pollutants, such as phenol, in water. This was attributed to the high density of Mn3+ ions on the {? 111} facet, which promoted direct oxidative capacity and generation of superoxide radical (O2??). The study also revealed a synergistic effect between non-radical and radical reactions, leading to greatly increased oxidative activity of 8-MnO2-{? 111}.
