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.
在本通讯中，通过在泡沫铜（CF）表面上的铜表面介导的格拉泽缩聚反应合成了富含碳的聚（1,3,5-三乙炔基苯）（PTEB）纳米纤维。基于PTEB/CF的光阴极呈现出创纪录的高且稳定的光电流密度-1.09 mA cm-2，比先前报道的结果高出100多倍。
