“…The acid treatment debundles the nanotubes and disposes functional groups on their sidewalls which serve as anchorage points for the ZnO nanoparticles. Aziz et al have dispersed CNT in sodium dodecyl sulphate followed by ball milling the ZnO that was previously obtained by hydrothermal synthesis [76]. CNT have also been grown by spray pyrolysis methods and purified thereafter to get rid of the iron impurities; they were then sintered at 700 ∘ C with ZnO prepared by oxidizing Zn dust at very high temperatures under oxygen rich conditions [77].…”

Photoluminescent ZnO carbon nanomaterials are an emerging class of nanomaterials with unique optical properties. They each, ZnO and carbon nanomaterials, have an advantage of being nontoxic and environmentally friendly. Their cost-effective production methods along with simple synthesis routes are also of interest. Moreover, ZnO presents photoluminescence emission in the UV and visible region depending on the synthesis routes, shape, size, deep level, and surface defects. When combined with carbon nanomaterials, modification of surface defects in ZnO allows tuning of these photoluminescence properties to produce, for example, white light. Moreover, efficient energy transfer from the ZnO to carbon nanostructures makes them suitable candidates not only in energy harvesting applications but also in biosensors, photodetectors, and low temperature thermal imaging. This work reviews the synthesis and photoluminescence properties of 3 carbon allotropes: carbon quantum or nanodots, graphene, and carbon nanotubes when hybridized with ZnO nanostructures. Various synthesis routes for the hybrid materials with different morphologies of ZnO are presented. Moreover, differences in photoluminescence emission when combining ZnO with each of the three different allotropes are analysed.

“…To synthesize ZnO NPs by this method, anhydrous ZnCl 2 and Na 2 CO 3 are used as starting materials and NaCl as a reaction medium and separator of ZnO NPs [4,40]. Several composites such as fluorapatite-zinc oxide (FAp-ZnO) composite nanopowder [41], Mn-doped ZnO nanoparticles [42], silver doped ZnO NPs [43], and carbon nanotubes (CNT)/ ZnO hybrid materials [44] have been synthesized by the mechanochemical process. Micron-and submicron-sized emulsions synthesis methods are usually referred to as microemulsions.…”

Zinc oxide (ZnO) is used for various purposes because of its special physico-chemical properties, including large band gap, high binding energy of exciton, nontoxicity, high chemical and thermal stability, large piezoelectric constants, and wurtzite crystal structure with various and widespread applications in electronics, optoelectronics, biochemical sensing, biomedical, and energy-saving systems. This review mainly aimed to present the recent improvement in ZnO-based composite materials with utilization in energy storage systems with a specific focus on lithium-ion batteries, dye-sensitized solar cells, and supercapacitors. The first part of this paper looks at the structure and properties of ZnO and then describes some of the most common synthesizing methods of ZnO composites, including electrochemical, chemical, solvo/hydrothermal, and physical deposition methods. Finally, the recent advancement of ZnO-based composite materials applied in energy storage systems was discussed.
