“…It is widely cultivated in different regions of Asia and native to Pakistan, while it is the least researched plants [30,31]. Hence, in continuation of our research being carried out by our group [32][33][34][35][36], in the present study, we have demonstrated the synthesis of CuO NPs using a solution combustion method using the leaf extract of P. emblica as fuel, which is a green alternative to synthetic-organic-compounds-based fuel such as glycine, urea, carboxymethylcellulose, DL-malic acid [37,38]. The synthesized nanoparticles were characterized by different techniques.…”

In the present study, a simple and eco-friendly route for the synthesis of copper oxide nanoparticles (CuO NPs) using leaf extract of Phyllanthus emblica as fuel has been demonstrated, as P. emblica is a locally available abundant plant. The formation of the as-prepared CuO NPs was confirmed by using various techniques, such as UV–Vis absorption spectroscopy, cold field scanning electron microscopy (CF–SEM), energy dispersive X-ray analysis (EDX), dynamic light scattering (DLS), and X-ray photoelectron (XPS). The hydrodynamic size of the CuO NPs was found to be 80 nm, while the zeta potential of -28.6 mV was obtained. The elemental composition was confirmed by EDX analysis accompanied with elemental mapping, while the crystalline nature was substantiated by the XRD diffractogram. The as-synthesized CuO NPs were studied for their use as an adsorbent material for the removal of As(V) from water. It was confirmed that the CuO NPs effectively removed As(V) via adsorption, and the adsorption efficiency was found to be best at a higher pH. The maximum adsorption capacity of CuO for As(V) was found to be 1.17 mg/g calculated using the Langmuir equation.

“…We show in this paper that solution combustion synthesis (SCS) − is versatile for preparing various compound stoichiometries within the Cu–V–O ternary family simply by varying the copper/vanadium mole ratio in a “one-pot” precursor mixture. Trends in the materials chemistry properties and photoelectrochemical (PEC) activity , are presented as are corresponding trends in polymorphic modifications and electronic band structures.…”

Solution combustion synthesis (SCS) is shown to be versatile for the rapid-one-pot synthesis of three compounds and four polymorphs in the Cu−V−O ternary family: α-CuV 2 O 6 , αand β-Cu 2 V 2 O 7 , and γ-Cu 3 V 2 O 8. These compounds feature copper/vanadium stoichiometric ratios ranging from 1:1 to 3:1; their structural, electronic, optoelectronic, and photoelectrochemical attributes were comprehensively characterized by a combination of theoretical and experimental techniques. The main contribution of the present study is the demonstration that a range of stoichiometries in this compound family can be derived simply by tuning the precursor mole ratio in the SCS procedure. The Cu−V−O family of samples, derived by SCS, is shown to exemplify the strong effect of compound stoichiometry on the optoelectronic and photoelectrochemical properties. Overall, α-CuV 2 O 6 showed the best performance, rooted in the direct nature of the optical transition in this material. Finally, SCS is very timeefficient and the various compositions can be obtained in a matter of minutes, as opposed to hours or even days in classical solution-based or ceramic synthesis routes.

Silver Oxide‐Based Semiconductors for Solar Fuels Production and Environmental Remediation: a Solid‐State Chemistry Approach

et al. 2018

View full text Add to dashboard Cite

A solid‐state perspective is offered for a discussion of silver‐based ternary and quaternary oxide semiconductors for applications related to solar fuels photogeneration and environmental remediation. The rather unique d10 electron configuration in these compounds is shown to impart interesting effects on their optoelectronic properties, and in turn, the photocatalytic activity of these compounds. This Minireview focuses on the structural aspects, electronic band structures, synthetic advances, and finally photoelectrochemical and photocatalytic applications of 32 compounds within the two oxide families, of the generic formula: AgxByOz or AgxByCnOz, where B and C are metals or non‐metals other than silver.
