文摘

SiNW covered with controllable amount of nanopores was successfully prepared. The photoelectrochemical stability of SiNW enhanced with the increase of the amount of nanopores. The introduction of nanopores increased special surface area of SiNW. Nanopores on SiNW exhibited improved photoelectrocatalytic reduction of Cr(VI).
