porous carbon block nanofiber composite and method for producing a porous carbon block nanofiber composite porous block nanofiber (110), a filtration system (10) and methods of using them are described. An exemplary porous block nanofiber composite (110) includes a porous block (100) having one or more pores (200). The porous block nanofiber composite (110) also includes a plurality of inorganic nanofibers (211) formed within at least one of the pores (200).
