Zhi en environmental protection electroplating energy storage

How does electroplating affect the environment?

The environmental impact of electroplating stems not only from the use of toxic chemicals but also from the significant water and energy consumption associated with the process. The wastewater generated can contain heavy metals and other toxic substances that, if not properly treated, can contaminate water bodies and soil.

Can Zvi particles be embedded in biochar with hydrothermal pretreatment?

We hypothesize that the ZVI particles can be intensively embedded and anchored in biochar with hydrothermal pretreatment to achieve the efficient decontamination of electroplating wastewater with limited passivation, high stability, and low environmental burden compared to the current Fe-based technology.

What are the environmental challenges of electroplating?

The process of electroplating presents various environmental challenges, primarily revolving around hazardous chemical management, wastewater treatment, and air quality control.

Can electrolyte additives improve the durability of ZIBs?

Furthermore, developing appropriate electrolyte additives to enhance the durability of Zn anodes is highly beneficial for the durability of ZIBs. However, current research in this area is lacking, making it a valuable and promising direction for further study.

Why is Zvi passivation layer 11 a high environmental burden?

The surface accumulation of toxic elements on the ZVI passivation layer 11 and easy transport of Fe particles leads to high mobility and bioavailability of pollutants under environmental disturbances 16, 23, and consequently, a high environmental burden.

Can biochar be used to reduce Zvi particles?

Thermal reduction with biochar can support the formation of ZVI particles without extra chemical consumption 25, and the carbon-negative nature of biochar can alleviate the life-cycle carbon emissions 26. Difficulties remain in stabilizing the ZVI particles on the biochar surface with controlled distribution and particle size.
