Seven Nigerian clays and clay minerals were characterized by multiple means with respect to their potential application in water purification other industrial areas. The morphology was determined of SEM while chemical/mineral compositions quantified using EDX, XPS XRD. FT-IR UV methods employed investigate the functional groups, inter alia physical chemical behaviours adsorbed species. stability aqueous solution zeta measurements. combined results revealed that are mostly kaolin illite,...
Abstract Here, a 4N‐in‐1 hybrid substrate concept (nanocolumnar structures, nanocrack network, nanoscale mixed oxide phases, and nanometallic structures) for ultra‐sensitive reliable photo‐induced‐enhanced Raman spectroscopy (PIERS), is proposed. The use of the leads to an ≈50‐fold enhancement over normal surface‐enhanced spectroscopy, which recorded as highest PIERS date. In addition improved signal, provides high detection sensitivity may be attributed activation possibility at extremely...
In recent years, semiconductor photocatalysts such as zinc oxide (ZnO) and titanium dioxide (TiO2) have been studied to utilize solar light for energy production environmental remediation. However, their wide band gap fast charge recombination limit practical applications. So far, various approaches, noble metal incorporation, coupling, the design of Z-scheme photocatalyst systems, among others, explored enhance lifetime photogenerated carriers in ZnO TiO2. this study, a novel TiO2-Ag-ZnO...
In recent years, defective TiO
Abstract Various methods are developed and used to treat oil‐contaminated water, including mechanical separation, chemical treatment, biological membrane filtration, sorption. Oil clean‐up via selective sorption of the oil by an engineered surface is most accepted technique due its high removal efficiency low cost. Here, a multifunctional providing highly capability photocatalytic decomposition proposed. This novel named as “three‐in‐one (3‐in‐1) surface” since it composed 1) layer, 2)...
The Cover Feature abstractly depicts the influence of a mixture argon (symbolized by pink) and hydrogen blue) on TiO2 pellet sample in hydrogenation process. blue cylinder center shows defective with an enhanced photocatalytic activity. green yellow corona around embodies this grey ellipse to right induced defects; Ti3+ site oxygen vacancy Vo.

Mixed metal oxide (MMO) nanoparticles (NPs) are hybrids consisting of two or more nanoscale oxides. Advantages MMO NPs over single oxides include improved catalytic activity, enhanced electrical and magnetic properties, increased thermal stability due to the synergy different components. This study presents a novel fabrication route for TiO2-CeO2 enriched with oxygen vacancies using Haberland-type gas aggregation cluster source. The NPs, deposited from segmented Ti/Ce targets under varying...
Selective Adsorption and Photocatalytic Clean-Up of Oil In article number 2102126, Josiah Shondo, Salih Veziroglu, Franz Faupel, O. Cenk Aktas, co-workers develop a novel surface named as “three-in-one (3-in-1) surface” since it is composed 1) highly photocatalytic layer, 2) micro- nano-structures, 3) low energy layer. This 3-in-1 selectively adsorbs the oil similar petroleum products (clean-up via photocatalysis) while exhibits extreme water repellence.
