Natural biowaste of banana peel-derived porous carbon for in-vitro antibacterial activity toward Escherichia coli

Banana peel-derived porous carbon from natural biowaste had been prepared with different annealing temperatures at 300, 400, 500, 600, and 700 °C. The as-prepared carbon powders were carefully characterized with XRD, SEM, TEM, EIS, and XPS measurements and their antibacterial activities were tested...

The as-prepared carbon powders were carefully characterized with XRD, SEM, TEM, EIS, and XPS measurements and their antibacterial activities were tested toward Escherichia coli (E. coli - ATCC 25922).
