Synthesis of S-doped hierarchical ZnO nanostructures via hydrothermal method and their optical properties

One-pot hydrothermal preparation of capsule-like nanocomposites of C/Ce-co-doped ZnO supported on graphene to enhance photodegradation

“…Besides, the recombination of electrons and holes on ZnO also lowers its photocatalytic activities. The modifications achieved by doping of metals, [3][4][5][6][7][8][9] rare earth metals, [10][11][12] non-metal elements, 13,14 oxides, [15][16][17][18][19] and carbon-based materials [graphene, graphene oxide (GO), or reduced graphene oxide (rGO)], [20][21][22] or codoping of both metal and non-metal elements to form composite materials 23,24 have been studied for years. The obtained materials lowered the band gap and inhibited the recombination of electrons and holes, which possibly promoted the photocatalytic activity of objective materials.…”

Cost-Effective Efficient Materials for Dye Degradation using Green and Facile Chemistry Routes

“…Zinc oxide (ZnO) has a wide band gap of 3.37 eV and a large excitation binding energy of 60 meV at room temperature (Yang et al 2017), making it a suitable candidate as a semiconducting material for vast applications in electronic and optoelectronic devices such as ultraviolet sensors (Capper et al 2011), solar cells, laser diodes, gas, and biosensor (Mustafa et al 2023;Giri et al 2016; Al-Hardan et al 2013; Zhao et al 2010). In addition, ZnO exhibits high conductivity, high optical transparency, and thermal stability (Zhan et al 2013) in a hydrogen-rich environment (Lee et al 2002).…”

“…Many researchers have reported that non-metal doping with N, C, or S impurities can effectively be modifying the optical properties and electronic structure of intrinsic ZnO (Bai et al 2012; Kumari et al 2019;Debbichi et al 2013). Among non-metal dopants, Sulphur (S) doped ZnO has more effective attention because of its size difference between S (1.84A°) and O (1.40A°) and high electronegativity (Yang et al 2017). It leads additional oxygen and zinc vacancies to develop, which promotes O 2 adsorption and the capture of photo-induced electrons, resulting in outstanding optical characteristics and high photocatalytic e ciency (Zhang et al 2012).…”

p–n junction induced electron injection type transparent photosensitive film of Cu2O/carbon quantum dots/ZnO

“…To date, many previous works about the transparent conductive ZnO have been reported, and provide us inspiring results. Some such research focuses on the doping (Zhu's group have prepared F and B co-doped ZnO film to improve the conductivity [10], Wang et al have fabricated S-doped hierarchical ZnO to increase the optical property [11]), aiming to regulate intrinsic properties of the materials. On the other hand, surface modification is also an effective way to improve the photoelectric responsiveness of the semiconductor, such as ion beam etching, electrochemical deposition, etc.…”
