  • The transformation of copper oxide(I) particles into ZVC was achieved through a one-step reduction process using ascorbic acid, resulting in hybrid products with differing copper content.
  • The study highlighted how the type of matrix influences the morphology of the copper particles, which is crucial for the materials' applications in creating functional nanocrystalline solids.

Article Abstract

Composite materials containing zero valent copper (ZVC) dispersed in the matrix of two commercially available strongly basic anion exchangers with a macroreticular (Amberlite IRA 900Cl) and gel-like (Amberlite IRA 402OH) structure were obtained. Cu particles appeared in the resin phase as the product of the reduction of the precursor, i.e., copper oxide(I) particles previously deposited in the two supporting materials. As a result of a one-step transformation of preformed CuO particles as templates conducted using green reductant ascorbic acid and under mild conditions, macroporous and gel-type hybrid products containing ZVC were obtained with a total copper content of 7.7 and 5.3 wt%, respectively. X-ray diffraction and FTIR spectroscopy confirmed the successful transformation of the starting oxide particles into a metallic deposit. A scanning electron microscopy study showed that the morphology of the deposit is mainly influenced by the type of matrix exchanger. In turn, the drying steps were crucial to its porosity and mechanical resistance. Because both the shape and size of copper particles and the internal structure of the supporting solid materials can have a decisive impact on the potential applications of the obtained materials, the results presented here reveal a great possibility for the design and synthesis of functional nanocrystalline solids.

Dioxygen (O) is a potent oxidant used by aerobic organisms for energy transduction and critical biosynthetic processes. Numerous metalloenzymes harness O to mediate C-H bond hydroxylation reactions, but most commonly feature iron or copper ions in their active site cofactors. In contrast, many manganese-activated enzymes─such as glutamine synthetase and isocitrate lyase─perform redox neutral chemical transformations and very few are known to activate O or C-H bonds.

Photocatalytic CO2 reduction to produce C2 products remains a challenge. Herein, Cu2O@Cu@NiAl-LDH composites with three-dimensional ordered core-shell structures were successfully prepared, and the effects of Cu2O with different exposed surfaces on CO2 photoreduction were investigated. The synergistic effect of zero-valent Cu and Cu+ as intermediate electron mediators retains more photogenerated electrons.

Article Synopsis
  • - The study explores a novel method using a CuCoO-modified phenylacetylene copper catalyst (PhCCu) to enhance the degradation of sulfisoxazole and other antibiotics in water through the activation of peroxymonosulfate (PMS).
  • - The modified catalyst showed a remarkable 29 times increase in efficiency compared to its unmodified version, achieving complete degradation of sulfisoxazole in just 5 minutes and effectively degrading nine different antibiotics.
  • - The degradation process primarily follows a non-radical pathway involving singlet oxygen and high-valent cobalt-oxygen species, which are stable against interference from various substances found in natural water.

Background: Trace elements, including zinc (Zn) and copper (Cu), although toxic at higher concentrations are known to play important roles in the maintenance of human health and neurodevelopment. Few epidemiological studies have investigated the association between prenatal or early postnatal Cu and Zn levels and child neurodevelopment. The aim of this research is to assess the association between child neurodevelopment at 18 months of age and cord blood and breast milk concentrations of Cu and Zn in Italian mother-child pairs enrolled in the Italian Northern Adriatic Cohort II (NAC-II), a part of the "Public health impact of long-term, low-level, mixed element exposure in susceptible population strata" project PHIME.

Article Synopsis
  • Electrochemical CO reduction can convert carbon dioxide into valuable energy sources, and two new copper-based organophosphonates have been developed to facilitate this process, focusing on turning CO into CHOH.
  • The two compounds, with distinct structures, show varying selectivity for producing CHOH as the main product and CHCOOH as a secondary product, with one compound achieving better results by reducing unwanted side reactions.
  • The effectiveness of these compounds as electrocatalysts is linked to their unique copper site ratios and stability of intermediates, making them potential candidates for photocatalytic applications as well.
