Facile fabrication of hollow tubular mixed oxides for selective catalytic reduction of NOx at low temperature: a combined experimental and theoretical study

A new versatile method was developed for the synthesis of various transition metal oxides with uniform 1D structures via electrospinning combined with heat treatment. The 1D nanowire or hollow tubular structure can be tuned by controlling heating rates. Interestingly, NOx conversion is ca. 99% at 200 °C in hollow tubular CuCo2O4.
