“…The slight shift in 2θ value of intense peak mainly attributed to doping of Fe +++ ion in lattice site of Ni ++ ion of NiO [ Figure a ] . Additionally, broadening of peaks for Fe doped NiO indicates its smaller particles size than pure NiO, which is further calculated by using Scherrer formula . Additionally, the lattice spacing is calculated by using Bragg ’ s law expressed in equation

true normaln λ = 2 dsin θ

We report the synthesis of NiO and Fe doped NiO nanoparticles by simple and cost effective Calotropis procera leaf extract assisted green co‐precipitation method. The leaf extract of Calotropis procera acts as reducing as well as capping agent for the synthesis of NiO and Fe doped NiO. The presence of –OH and aldehydic group (‐CHO) on synthesized nanoparticle imparts their strong interaction with synthesized nanoparticles, conveying efficient catalyst for heterocycle synthesis. The proficient catalytic application of biogenic NiO and Fe doped NiO NPs were explored in aqueous hydrotropic solution for syntheses of diaryl pyrimidinones at room temperature. The synthesized catalysts are efficient in terms of yield, reaction time and reusability. The NiO or Fe doped NiO/NaPTS/27°C is efficient, highly sustainable catalytic system for heterocycle synthesis at room temperature. Accordingly, Fe doped NiO/NaPTS proved to be a better catalytic system than NiO/NaPTS in water.

“…ZnO NPs at pH 11 and pH 12 showed 3.01 and 3.17 eV band gap, respectively. The particle size of nanoparticles decreases with increase in band gap . Figure b indicates that there is an increase in band gap from 3.01 eV to 3.17 eV when there is the increase in pH from 11 to 12, implying a decrease in particle size.…”

We investigated pH transformed ZnO NPs viz ZnO nanobullets and ZnO nanograins at pH 11 and 12 respectively, synthesized by co‐precipitation method. The structural, morphological, chemical, compositional and optical properties of synthesized ZnO NPs were analysed by using X‐ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X‐ray Spectroscopy (EDAX) and Ultra‐Violate Visible spectroscopy (UV‐Vis). The Noteworthy feature of ZnO NPs in presence of NaPTS leads a speedy formation of flavanones from the reaction of an aldehyde and o‐hydroxy acetophenone. Thus, it imparted the first room‐temperature brisk synthesis of flavanones in an aqueous medium.

“…83 After the successful synthesis of Fe-doped NiO NPs, Shinde et al synthesized Ni@ZnO NPs and used them as a catalyst for the synthesis of 3,4-dihydropyrimidin-2(1 H )-ones [Scheme 28] in water with the NaPTS hydrotrope. 84 In these environmentally conscious times, researchers are required to focus on developing green methodologies for organic transformations. 85 To fulfill this requirement, Baig and Varma reported the microwave-assisted nano-ferrite NP-catalyzed Paal–Knorr reaction in water.…”
