Anchoring of polymeric precursor on oxygen deficient ZnO nanotubes: A chelation assisted combined nucleation-growth-dissolution synthesis strategy

Bromine‐Induced Defects in Anion‐Deficient Zinc Oxide as Stable Photocatalysis Promoters

“…Relatively higher defect emission is observed in 6DZ compared to other samples . The emission peaks at 485 and 528 nm are assigned to oxygen vacancies and crystal defects in the prepared nanosystems …”

“…The strategy for synthesising bromine doped short nanotubes of ZnO is shown schematically in Figure . As reported in our previous work, the versatile performances of β‐aminoethylamine precursor direct the formation of ZnO nanotubes with sufficient oxygen vacancies . Here, we focus on bromine incorporation in ZnO, which can alter the physico‐chemical properties without changing the crystal structure of ZnO to increase the photocatalytic activity.…”

“…During the growth process of nanotube, the nonpolar surfaces become relatively stable compared to polar surfaces because the β‐Aminoethylamine covers the surface of the former. The growth happens along oxygen atom terminated Zn polar surfaces with dissolution of O 2− rich polar surfaces …”

“…The undoped ZnO contains enormous oxygen vacancies which have been reported already . In doped samples, the synergetic effect contributed by bromine induced surface defects and oxygen vacancies enhances the photocatalytic activity.…”

A simple synthesis of ZnO:Co2O3 nanocomposites by pulsed laser irradiation in liquid

“…A photocatalyst can help for the purification of nature as dye decay, anti-pollutants, self-cleaning mechanism etc. [16] , [17] , [18] . Photocatalysts can used in the areas of cleaner and renewable energy through hydrogen evolution reactions, water splitting reactions which will reduce the CO and CO 2 emission from biofuels by replacing them [19] , [20] .…”
