Capacitive deionization (CDI) displays the merits of having eco-friendliness and low energy consumption when capturing phosphorus. However, traditional carbon electrodes often suffer from the limitation that phosphorus uptake sites are insufficient.

Herein, a novel ZrO₂ nanoparticle equipped with a highly conductive carbon network (NZrC) was fabricated by a facile co-pyrolysis process. Na₂EDTA can provide additional carbon backbones, N species, and metal chelation sites. Zr-MOF was applied as the ZrO₂ precursor with abundant phosphorus trapping sites. The results suggested that Na₂EDTA favors improving the ZrO₂ dispersion, mesoporous channel formation, and pseudocapacitive behavior.

By leveraging nano-bubbles produced through the reaction between AC and NaOH without adding other pore-forming agents, the membrane-forming process of PSf was regulated.

It was found that the PSf LNF membranes prepared in NaOH-solution coagulation and immersion baths exhibited significantly enhanced permeation performance without compromising the rejection. These results suggested that the coagulation and immersion post-treatment processes under NaOH solution had a great effect upon the structure and the property of the membranes.

The LNF membrane prepared from 20 wt% PSf casting solution with 8 wt% AC achieved a permeation flux of 188.7 L m⁻² h⁻¹, […]

In this paper, the sandwich PEDOT:PSS@MXene film electrode was prepared by uniformly coating PEDOT:PSS film on the surface of MXene through template-assisted polymerization. The film improves the stability of the composite by protecting the Ti layer.

The specific capacitance of PEDOT:PSS@MXene performs 185.5 F g⁻¹ at 5 mV s⁻¹. The desalination capacity of hybrid AC//PEDOT:PSS@MXene cell in 500 mg L⁻¹ NaCl solution is 35.8 mg g⁻¹.

After 40 desalting cycles, the cell performs better retention rate than AC//MXene cell (82.5 %), which keeps 97.2 %.

The morphology and structure of composite show no exists of TiO₂ […]
