Article Abstract
A novel facile combination of precipitation and plasma discharge reaction is successfully employed for one-step synthesis of an α-FeO-FeO graphene nanocomposite (GFs). The co-existence and anchoring of hematite (α-FeO) and magnetite (FeO) nanoparticles onto a graphene sheet in the as synthesized GFs were verified by results of XRD, Raman, SEM, TEM, and XPS. HRTEM characterization was used for confirming the bonding between α-FeO/FeO nanoparticles and the graphene sheet. Consequently, GFs shows superior photodegrading performance towards methylene blue (MB), compared to individual α-FeO/FeO nanoparticles, as a result of band gap narrowing and the electron-hole pair recombination rate reducing. Moreover, GFs allows a good possibility of separating and recycling under an external-magnetic field, suggesting potential in visible-light-promoted photocatalytic applications.

A visible light-driven, KSO-mediated one-step synthesis of 2-halo glycals has been reported, employing potassium salts as halogen source (KI, KBr, and KCl). Versatility of the proposed methodology to generate chloro-, bromo-, and iodo-substituted d-glycals containing both aliphatic and aromatic substitutions emphasizes the reproducibility of the methodology. The synthesized halogenated derivatives were subjected to Suzuki, Heck, and Sonogashira cross-coupling reactions, showcasing the utility of the halogenated derivatives for subsequent C-2 functionalization reactions of d-glycals.

Deuterated compounds possess significant research value. As interest in chiral deuterated compounds intensifies, various deuteration methods are garnering increased attention. This article primarily reviews the asymmetric deuterium synthesis methods reported in recent years, focusing on the following strategies: one-step reductive deuteration, the series reaction of H/D exchange and asymmetric allylation, the [3+2] asymmetric cycloaddition of 1,3-dipoles and alkenes, asymmetric deuteration photocatalysis, asymmetric deuteration using organic catalysis, and asymmetric deuteration of chiral amino acids and their derivatives through biocatalysis.

Conventional synthesis methods, such as solvothermal, hydrothermal, and solid-state, require long synthesis times, the use of solvents and surfactants, and several separation steps. However, the preparation of coated SnS composites using liquid media is even more complex, requiring suitable precursors, compatible solvents, and potentially several steps.

Molybdenum disulfide (MoS) has recently emerged as a promising material for the development of triboelectric nanogenerators (TENGs) owing to its inherently negative triboelectric properties when paired with polymeric layers, along with its notable transparency and mechanical flexibility. However, MoS-based TENGs operating in the contact-separation mode encounter critical limitations, including mechanical wear and limited triboelectric performance, particularly within the constraints of conventional 2D geometries. This paper reports the novel one-step laser-assisted synthesis of hemispherical MoS through the controlled nucleation and growth of MoS precursor seeds.

Electrocatalytic synthesis of ammonia is a sustainable, cost-effective alternative method for producing renewable electricity and can operate under milder conditions than the traditional Haber-Bosch method. We report direct laser-induced synthesis of copper nanocatalysts embedded in graphitic films for the synthesis of ammonia. Laser-induced metal-embedded graphene (m-LIG) offers many advantages, such as fast and simple synthesis, shape design of the electrodes, and direct printing on any substrate, including thermally sensitive plastics.
