Summary: Mimicking natural photosynthesis by using carbon nitride-based photocatalysts to convert solar power into hydrogen energy has been hindered by the addition of metallic cocatalysts. To overcome this issue, a metal-free photocatalytic system was developed by grafting nitrogen-doped graphene quantum dots (NGQDs) onto porous ultrathin carbon nitride (PUCN). The integration of N-GQDs enhanced the hydrogen production rate of the photocatalyst by 208 times compared to PUCN. This new metal-free photocatalyst outperforms most carbon nitride-based photocatalysts with metallic cocatalysts, offering potential for practical applications in photocatalytic water splitting.

Summary: This work reported a significant improvement of nanofiltration (NF) membranes for desalination with high separation performance. The graphene quantum dots (GQDs) enhanced polyamide (PA) composite membranes (GPA) consisted of porous substrates and nanofilms.

Summary: This paper develops a novel approach for evaluating charged particles' collision probability in the external electric field of a regular two-stage electrostatic precipitator. Numerical simulation is used to analyze the factors influencing particle collision, with results showing that the R-AC external electric field is more beneficial for particle collision. Frequency and plate spacing do not have a significant impact on collision probability, while applied voltage has a promotional effect. The dimensionless coefficient analysis provides valuable information for optimizing working conditions in different types of external electric fields.
