Electrochemical properties of Euphorbia pulcherrima mediated copper oxide nanoparticles

Feasibility Study of the Euphorbia pulcherrima Plant Extract as Natural Dye with Different Mordants for Fabric Dyeing

“…The peaks at 3408 cm -1 , 2926 cm -1 , 1605 cm -1 , 1420 cm -1 , and 1060 cm -1 represent the O-H stretching, C-H stretching, C=O stretching, aromatic C=C stretching, and C-O chelate ring, respectively. These FTIR spectra peak values are in agreement with the results reported for the Hibiscus rosasinensis and Euphorbia pulcherrima extracts (Adebayo et al, 2007, Ramprasath et al, 2017, Sackey et al, 2020. In a comparative FTIR analysis the redcolored band that was found to be the major active phytocomponent of the crude extract with a characteristic peaks of 1,2,3-benzenetriol as major constituent of GC-MS in Table 2.…”

“…The aqueous extract of E. pulcherrima in crude form and red-colored components obtained from the column were applied to different fabric dyeing, especially in cotton by using natural and synthetic mordants. Color shades developed by different mordants at different conditions are summarized in Table 3 using standard procedures as reported elsewhere (Adebayo et al, 2007;Kumar & Prabha, 2018;Malla, 1993;Sackey et al, 2020). Other factors such as pH, solvent, dye concentration, mordant concentration mordant variation that influence the color shade and wash fastness of dyeing colors and their optimization should be explored.…”

“…However, the ethanol extract of E. pulcherrima leaves was used to sensitized-ZnO photoelectrodes with an efficiency of 1.29 to 1.66 % (Naresh Kumar et al, 2017Silwal et al 2019). Similarly, copper oxide nanoparticles were bio-synthesized from red leaves extract of E. pulcherrima plant that showed one of the promising materials for electrochemical energy storage applications (Sackey et al, 2020).…”

Green synthesis of copper oxide nanoparticles for biomedical application and environmental remediation

“…Many researchers have reported various approaches of synthesizing CuONPs, among which we have ultrasound irradiation hydrothermal, biosynthesis approaches, electron beam lithography, solid-state reaction, sol-gel, template methods using surfactants, microwave-assisted protocol, decomposition of copper acetate and sonochemical synthesis [ 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. It has also been reported that method of CuONPs synthesis affect their morphological properties and toxicity behaviour [ 29 ].…”

Low‐temperature oxidation of metal nanoparticles obtained by chemical dispersion

“…In this regard, new types of nanomaterials and technologies for their synthesis are created every year [1,2]. A complex of unique properties in the nanostate makes nanomaterials an attractive field of research [3,4] and applications of nanomaterials are constantly expanding [5,6]. Highly dispersed metal powders are particularly effective for the intensification of technological processes in powder metallurgy and ceramic production, as well as for the creation of new wear-resistant and heat-resistant materials [7][8][9].…”
