Abstract

In this communication, a carbon-rich poly(1,3,5-triethynylbenzene) (PTEB) nanofiber is synthesized via a Cu-surface mediated Glaser polycondensation on a copper foam (CF) surface. The PTEB/CF based photocathodes present a record-high and stable photocurrent density of -1.09 mA cm-2, more than 100 times higher than the previously reported results.
