Filtration-enhanced highly efficient photocatalytic degradation with a novel electrospun rGO@TiO2 nanofibrous membrane: Implication for improving photocatalytic efficiency

•Electrospun rGO@TiF membranes have advanced photocatalytic degradation capability.•Filtration-enhanced degradation is 2.15 times as much as that without filtration.•Filtration-induced improvement could be attributed to enhanced mass transfer.•Filtration might inhibit electron–hole recombination thus more effective radicals.•rGO@TiF membrane performs stably over ten degradation cycles.
