“…According to Ningsih et al, the decrease in band gap value is caused by the interaction between the electron band and the delocalization of electrons in transition ions so that metal ion substitution is formed (Ningsih et al, 2021). In addition, the reduced band gap value causes the distance between the valence band and the conduction band to get closer and electron excitation becomes faster so that less photon energy is needed for electron excitation from the valence band to the conduction band (Ningsih et al, 2019). This shows that the greater the band gap value to the insulator, the greater the photon energy required for electron excitation from the valence band to the conduction band.…”

The need for electrical energy is increasing with the increase in the economy and population in Indonesia. Fossil energy sources are used as fuel to produce electrical energy and will run out if used continuously. Fossil energy sources can be replaced by using New Renewable Energy (NRE) to meet national electrical energy needs. The purpose of adding additives in this study is to observe the effectiveness of the addition of DEA on the band gap value, crystal phase, and surface morphology on SnO2. In this study using the sol-gel method for the synthesis of SnO2. The sol-gel method is the conversion of monomers into colloidal solutions (sol) which serve as precursors for integrated networks (gels) either discrete particles or network polymers. SnO2 nanomaterials will be characterized by UV-DRS Spectrophotometer. The results of characterization of SnO2 nanomaterials with the addition of Diethanolamine additives as much as 1.5 mL have obtained a band gap value of 3.60 eV.

“…Use of additives during sol-gel synthesis process also affects the properties of the synthesized nanomaterials. For example, it was observed by Ningsih et al (2019), that adding egg white (albumin) during synthesis of Al-ZnO nanoparticles can affect the band gap structures and particle size. The particle size decreased from 16.67 to 13.82 nm with an increase in the quantity of the egg white from 10 to 30 mL.…”

In recent years, research on improving the synthesis of catalysts has been at the forefront because of advancements in nanotechnology and greener conventions. Using ultrasound (US) during nanocatalysts synthesis is one of the green approaches that can yield improved catalyst characteristics under conditions of shorter reaction time and requirement of low temperature and pressure. The current paper aims at giving an insight into US‐assisted synthesis (emphasized on sol‐gel and hydrothermal) of different metal oxide nanocatalysts. It has been elucidated that US‐assisted synthesis gives nanocatalyst with narrower particle size distribution with lower mean size, higher surface area, better morphology with less agglomeration, and higher catalytic activity. Ultrasound has thus been demonstrated to yield improvements in morphological, optical, and electronic properties of the nanocatalysts, however, scalability and industrial application of sonochemical synthesis have not been seen very popular. Some guidelines for future research into the development of novel nanocatalysts and industrial scale‐up studies are also provided. The review also summarizes the application of these metal oxides as photocatalysts for dye degradation or effluent treatment containing dyes, highlighting the fundamentals of photocatalysis as well. A comparative study has been reported for catalysts obtained using the US‐assisted synthesis and conventional synthesis of the photocatalysts in terms of catalytic activity. The benefits of using ultrasound‐assisted synthesis in terms of higher photocatalytic degradation have been clearly demonstrated.

“…Electrical and optical properties are what make this semiconductor widely applied to gas sensors, catalysts, to solar cell conversion. ZnO is a semiconductor group II-VI [4] because, in the periodic table, zinc and oxygen are group II and group VI respectively. ZnO has a band gap of 3.37 eV [5] with the ability to bind free electrons of 60 MeV at room temperature [6].…”

Synthesis of Cu<sup>2+</sup> Doped ZnO by the Combination of Sol-Gel-Sonochemical Methods with Duck Egg Albumen as Additive for Photocatalytic Degradation of Methyl Orange

Cu2+ doped ZnO by green synthesis was successfully prepared by using a combination of the Sol-Gel-Sonochemical method. Duck egg albumen was used as an additive, a substitute for chemical additives, such as monoethanolamine (MEA) and diethanolamine (DEA). Zn(CH3COO)2·2H2O was used as a precursor, Cu(CH3COO)2·H2O was used as a dopant source with concentrations of 5 wt.%, and isopropanol was used as the solvent. The addition of albumen variations was 10, 20, 30, 40, and 50 mL. The prepared catalyst was applied for the degradation of the methyl orange dyes by using photosonolysis with variations of the degradation time of methyl orange for 30, 60, 90, 120, 150, 180, and 240 min. FTIR spectra showed stretching at 400–550 cm–1 indicating the presence of Zn–O and Zn–O–Cu metal oxides. The optimum bandgap energy value was 2.82 eV with the addition of 30 mL of albumen. XRD analysis showed the optimum particle size of 16.62–53.21 nm after adding 30 mL of additives. The SEM image showed a spherical shape with an average diameter of 2.7 μm. The optimum percentage of degradation obtained was 94.88%, with the irradiation time under UV light for 210 min.
