Recent Advances in LDH/g-CN Heterojunction Photocatalysts for Organic Pollutant Removal.

Environmental pollution has been decreased by using photocatalytic technology in conjunction with solar energy. An efficient method to obtain highly efficient photocatalysts is to build heterojunction photocatalysts by combining graphitic carbon nitride (g-CN) with layered double hydroxides (LDHs). In this review, recent developments in LDH/g-CN heterojunctions and their applications for organic pollutant removal are systematically exhibited.

Fabrication of highly dispersed ultrafine CoS nanoparticles on carbon nanofibers as low-cost counter electrode for dye-sensitized solar cells.

Platinum is the most commonly used dye-sensitized solar cell (DSSC) counter electrode (CE) due to its superior electrocatalytic activity and high transparency. However, the scarcity and high-cost of Pt restrict its practical application for the large-scale production of DSSCs. Herein, a facile approach for fabricating highly dispersed CoS nanoparticles with small diameters in the range of 5-10 nm on the surface of carbon nanofibers (CNFs) via an electrospinning followed by calcination and hydrothermal reaction was developed.
