erein, flexible, magnetic and hierarchical porous catalytic
carbon nanofibrous membranes (MnO/Co@SiO
2
-CNFMs)
driven by gravity were prepared by co-electrospinning technique
and self-reduced pyrolysis. Benefiting from the active metals and
precursor carrier design, the composite active MnO/Co crystals
can be directly produced without any reducing gases and easily
migrate to carbon nanofiber surface during the carbonization
process. Meanwhile, the silica nanoparticles (SiO
2
NPs) doped
in carbon nanofibers (CNFs) can maintain the carbon nanofiber
structure without obvious shrinkage as well as transmit and
scatter the outer stress, which endowed the membrane with
robust flexibility. The as-preparedMnO/Co@SiO
2
-CNFM exhibited
a superhydrophilic surface with a water contact angle of 0°, fast
water flux of 752±28 L/m

h, prominent catalytic performance
with a high degradation efficiency over 99.5% toward methylene
blue (MeB). Most importantly, the amount of wastewater treated
by gravity driven catalytic membrane was about four times the
static degradationwithout external driven force. Furthermore, four
typical refractory pollutants (phenol, bisphenol-S, chlorophenol
and sulfaethoxazole) also can be efficiently degraded by gravity
driven MnO/Co@SiO
2
-CNFMs/PMS system. This study is
meaningful for the development of novel catalytic membrane
with high efficiency and low energy consumption for wastewater
treatment.
