A series of three-dimensional (3D) porous nanocomposites, comprised partially reduced graphene oxide (pRGO) and CO32– containing Mg–Al layered double hydroxide, were synthesized in two steps. In the first step, (GO) was fabricated by a modified Hummers’ method, and, subsequently, second step hydroxide (LDH) nanosheets homogeneously grown on surface GO sheets an situ crystallization approach, involving facile coprecipitation technique. The alkaline medium used for growth LDH resulted partial...
Magnetic cobalt ferrite–carbon nanotube nanocomposites are effective and reusable adsorbents for remediation of wastewaters contaminated with dyes.
Semiconductor photoelectrodes are regularly coupled to solid-state heterogeneous catalysts perform solar-driven reduction of CO2. Less frequently, molecular employed better control the reactivity toward desired products, yet development robust semiconductor/molecule interfaces has proven challenging. Here, we demonstrate that a 2-3 nm thermal oxide layer on Si exhibits stability in aqueous solution, high photovoltage, and photocurrent density ∼10 mA/cm2 for photoelectrochemical homogeneous...
Nitrogen-functionalized multiwalled carbon nanotubes synthesized were effective and efficient for the removal of Cu<sup>2+</sup> from aqueous solutions.
Mn doped zirconia is utilized as an environmental-friendly and efficient catalyst for ultrasound mediated four-component coupling reaction, containing dimethylacetylenedicarboxylate/ethyl acetoacetate, hydrazine hydrate, malononitrile, aromatic aldehyde. These reactions were performed under green solvent conditions, to yield pyrano[2,3-c]pyrazole-3-carboxylate/pyrano[2,3-c]pyrazole-5-carbonitrile derivatives (5a–g 7a–g) with good excellent yields (88–98%). The structures of the compounds...
The pH-dependent adsorption of ibuprofen (IBP) onto acid-functionalized multiwalled carbon nanotubes (CNT-COOH) was investigated by batch experiments and quantum mechanics (QM) molecular (MM) simulation. A force field developed applied for monitoring interactions between IBP CNT-COOH. Our simulations relied on the behavior pH-sensitive CNT-COOH functional groups molecules in solution, which occur as neutral or deprotonated species. QM MM calculations were performed to determine binding...
This study assessed the material and chemical compositions methods of disposal end-of-life non-rechargeable electric torches (EOLNETs). Thirty EOLNETs ten different models were collected in Lagos, Nigeria. Total heavy metals plastic PWB components samples determined using CPSC-CH-1002-08 EPA 3050B methods. Questionnaires distributed to 200 unselected respondents assess usage EOLNETs. The result showed that is most abundant component waste with a mean composition 70.9%. levels Cd, Cr Ni low....
Carbon electrodes are ideal for electrochemistry with molecular catalysts, exhibiting facile charge transfer and good stability. Yet solar-driven catalysis semiconductor light absorbers, stable semiconductor/carbon interfaces can be difficult to achieve, carbon's high optical extinction means it only used in ultrathin layers. Here, we demonstrate a plasma-enhanced chemical vapor deposition process that achieves well-controlled of out-of-plane "fuzzy" graphene (FG) on thermally oxidized Si...
Abstract Herein, we report on (a) the application of cobalt(II) tellurium oxide (Co 3 TeO 6 ) as a photo‐electrocatalyst, to enhance photo‐electrocatalytic (PEC) oxygen evolution reaction (OER) in alkaline media, compared electrocatalytic (EC) OER (in absence light), and (b) store charge upon illumination release termination under potential bias conditions. These nanomaterials were synthesized employing sol‐gel method calcined at temperatures ranging from 400 1100 °C. They physically...
