The photocatalytic efficiency of a thin-film TiO2-coated nanostructured template is studied by dye degradation in water. The nanostructured template was synthesized by metal-assisted wet etching of Si and used as substrate for the deposition of a thin film of TiO2 (10 nm thick) by atomic layer deposition. A complete structural characterization was made by scanning and transmission electron microscopies. The significant photocatalytic performance was evaluated by the degradation of two dyes in water: methylene blue and methyl orange. The relevance of the reported results is discussed, opening the route toward the application of the synthesized nanostructured TiO2 for water purification.

To improve water splitting efficiency and enhance energy utilization, it is crucial to develop catalysts with excellent activity, long-term stability, and low cost. In this study, we synthesized a three-dimensional nanostructured amorphous CoMoP/NF bifunctional catalyst for both the hydrogen evolution reaction (HER) and the 5-hydroxymethylfurfural oxidation reaction (HMFOR), using a sacrificial template method. Benefiting from element doping regulation and morphology control, CoMoP/NF exhibited outstanding catalytic activity.

Cytosine-rich and poly(adenine)-tailed tetrahedral DNA framework (TDF) is designed as template (A-TDF) for anchoring silver nanoclusters (AgNCs) and igniting the dual-color fluorescence of AgNCs. The resultant DNA-AgNCs simultaneously emits red and green fluorescence, and the quantum yield of red fluorescence is as high as 44.8%.

As a sustainable alternative technology to the cost- and energy-intensive Haber-Bosch method, electrochemical nitrogen (N) reduction offers direct conversion of N to NH under ambient conditions. Direct use of noble metals or non-noble metals as electrocatalytic materials results in unsatisfactory electrocatalytic properties because of their low electrical conductivity and stability. Herein, three-dimensional flexible carbon nanofiber (CNF/TiO@CoS) nanostructures were prepared on the surface of CNF by using electrospinning, a hydrothermal method, and in situ growth.

Carbon nanostructures (CNs) are various low-dimensional allotropes of carbon that have attracted much scientific attention due to their interesting physicochemical properties. It was quickly discovered that the properties of CNs can be significantly improved by modifying their surface or synthesizing composites containing CNs. Composites combine two or more materials to create a final material with enhanced properties compared with their initial components.

Article Synopsis
  • Efficient electrocatalysts, especially medium-entropy oxides (MEOs), are essential for improving the hydrogen evolution reaction (HER) due to their unique properties like multiple components and lattice distortion.
  • This study utilizes soluble soybean polysaccharide (SSPS) as a template to create an FeCoNiO/C composite, which enhances the formation of important features such as oxygen vacancies and a favorable nanoparticle shape.
  • The resulting O vacancy-modified FeCoNiO/C composite shows excellent HER performance, requiring only 61 mV overpotential for achieving a 10 mA cm current density, indicating its potential as an effective electrocatalyst for industrial use.
