Figure 2

Nickel oxide (NiO) quantum dot (QD)-coated CNTR. (a) SEM image of a representative CNTR coated with NiO QDscolloids (NiO-1.0). (b) EDX spectrum confirming the presence of NiO QDs on CNTR. Fe and S signals originate from the residual catalysts, and Cu originates from the TEM grid. (c) TEM micrograph of NiO@CNTR, and the inset shows the crystalline phase of the cubic NiO and (002) plane of CNTs. (d) Representative lattice-resolved HRTEM image of NiO@CNTR showing the high-resolution view of NiO particles on the CNTR matrix.
