the EE and power capability were severely limited [49]. Therefore, in order
to improve the electron and ion transport capability, they prepared a GO
nanosheets/multi-walled carbon nanotubes (GO/MWCNTs) hybrid, as
shown in Figure 9.18c and d, by an electrostatic spray technique on a
glassy carbon electrode (GCE) after efcient ultrasonic treatment [50]. The
results showed that after the introduction of GO nanosheets (Figure 9.18a),
MWCNTS (Figure 9.18b) formed an electrocatalytic hybrid with a mixed con-
ducting network. Compared with the pure GO nanosheets and MWCNTs,
GO/MWCNTs hybrid electrode exhibited much better ...
