Non-thermal plasma enhances performances of biochar in wastewater treatment and energy storage applications
文献摘要：
Surface functionalization or modification to introduce more oxygen-containing functional groups to biochar is an effective strategy for tuning the physico-chemical properties and promoting follow-up applications.In this study,non-thermal plasma was applied for biochar surface carving before being used in contaminant removal and energy storage applications.The results showed that even a low dose of plasma exposure could introduce a high number density of oxygen-functional groups and enhance the hydrophilicity and metal affinity of the pristine biochar.The plasma-treated biochar enabled a faster metal-adsorp-tion rate and a 40％higher maximum adsorption capacity of heavy metal ion Pb2+.Moreover,to add more functionality to biochar surface,biochar with and without plasma pre-treatment was activated by KOH at a temperature of 800℃.Using the same amount of KOH,the plasma treatment resulted in an activated carbon product with the larger BET surface area and pore volume.The performance of the treated activated carbon as a supercapacitor electrode was also substantially improved by＞30％.This study may provide guidelines for enhan-cing the surface functionality and application perfor-mances of biochar using non-thermal-based techniques.
