Organic Solvent Assisted Growth of Flower-like ZnO for Enhanced Photocatalytic Activities

A theoretical and experimental investigation of Eu-doped ZnO nanorods and its application on dye sensitized solar cells

“…The ZnO has advantages over the porous TiO 2 , such as higher electron diffusivity, a higher electron mobility, is available at low-cost, and stability against photocorrosion [11,12]. In addition, the polar surfaces of the wurtzite crystalline structure enables the growth of many kinds of ZnO nanostructures [13], including nanowires [14], nanorods [15], nanobelts [16], nanosprings [17], nanorings [18], nanobowls [19], nanoflowers [20], and nanohelices [21]. Among all these structures, in particular, the one dimensional (1-D) ZnO nanostructures, like as nanorods and nanowires, have received increasing attention in recent years, due to its excellent physical and chemical properties, which can provide an effective direct pathway for rapid transport of the photoelectrons and a higher surface area for dye adsorption, enhancing the photovoltaic performance of the DSSCs [22e24].…”

Carbon quantum dots decorated N-doped ZnO: Synthesis and enhanced photocatalytic activity on UV, visible and daylight sources with suppressed photocorrosion

“…The progress towards the development of efficient photo- 12 catalyst is a critical issue for an environmental remediation due to 13 major organic contaminants originated from the textile and food 14 industries. The malachite green (MG) dye is largely used to color in 15 silk, wool and leather industries and it is extremely toxic to fish 16 [1,2].…”

“…The usage of CQDs are being acknowledged due to the 38 characteristic photo-induced electron transfer [7] and up-conver-39 sion of photoluminescence properties [3]. Hence, a new type of 40 photocatalyst, CQD decorated N-doped ZnO (CQD/N-ZnO) was 41 prepared for higher photocatalytic performance due to the 42 combinational effect of N-doping [8] together with the carbon 43 nanoparticle [5][6][7][8][9][10][11][12][13] ethanol several times and dried [14]. 400.1 eV.…”

Improved daylight-induced photocatalytic performance and suppressed photocorrosion of N-doped ZnO decorated with carbon quantum dots

“…The primary diffraction peaks appeared at 2q values of 31.7, 33.4 and 36.2 , representing the (100), (002) and (101) crystal planes of ZnO. 12 For the CQD/N-ZnO composite, a broader diffraction peak appeared near 26 , attributed to the graphitic (002) peak, together with a slight shi (36.21 to 36.08 ) in the (002) diffraction peak, as clearly seen in the enlarged XRD patterns between 35 and 40 (Fig. 1b).…”
