Preparation of double functional carbon-based ZnO derived from rape straw for dye wastewater treatment

Xiaojing Qin et al.

Summary: Rape straw waste was converted into double functional carbon-based ZnO (RS/ZnO) by activation with ZnCl2, and it showed excellent adsorption and photocatalytic properties for the removal of rhodamine B (RB) and evans blue (EB) in wastewater. The adsorption mechanism involves hydrogen bonding, pi-pi interactions, electrostatic attraction, pore filling, and surface complexation. The adsorption amount of EB is higher than RB, which is supported by density functional theory calculations. The photocatalytic degradation of RB and EB reached close to 100% under UV irradiation, and the generated ·OH and ·O2(-) were responsible for the degradation process, as confirmed by electron paramagnetic resonance spectrometer analysis. This work demonstrates the potential of utilizing rape straw waste for dye wastewater purification.

Enhancing peroxymonosulfate activation by Co-Fe layered double hydroxide catalysts via compositing with biochar

Quanyun Ye et al.

Summary: Efficient and low-cost catalysts for peroxymonosulfate (PMS) activation are essential for pollution prevention and environmental remediation. In this study, biochar (BC) was composited with CoFe layered double hydroxide (CoFe-LDH) to achieve enhanced PMS activation. The synergistic effect between BC and CoFe-LDH resulted in improved catalytic activity and stability, leading to higher production of reactive oxygen species (ROS) in the BC-LDH/PMS system. The degradation efficiency of dimethyl phthalate (DMP) was significantly higher in the BC-LDH/PMS system compared to the CoFe-LDH/PMS system, reaching 100% within 60 minutes.
