Electrochemical semi-hydrogenation of alkynols to produce high-value alkenols is a green and sustainable approach. Although Pd can exhibit excellent properties, its intrinsic mechanism still lacks in-depth study. Herein, proton ionic liquid (PIL)-modified metallene (Pdene@PIL) synthesized for the electrocatalytic 2-methyl-3-butyn-2-ol (MBY) 2-methyl-3-buten-2-ol (MBE). The PIL modification Pdene@PIL resulted in an MBY conversion 96.1% MBE selectivity 97.2%, respectively. Theoretical calculations indicate electron transfer between Pdene PIL, leading easier adsorption on surface. d-band center shifts away from Fermi level, which weakens over-hydrogenated intermediates.

Green hydrogen production technology is an effective strategy for solving energy problems and environmental issues. In this paper, we report a bipolar system: Au–CuxO/CF∥Ru–CuxO/CF, in which the cathode produces through evolution reaction (HER) process anode formaldehyde oxidation (FOR). It found that when Au–CuxO/CF used FOR, C–H bond of will be broken at low potential to produce reactive H*. H* recombined Tafel step (H* + ⇌ H2) H2. At same time, oxidized high-value-added product HCOOH. We formation grain boundary-rich structures on Au–CuxO surface jointly promotes potentials. addition, introduced Ru elements into CuxO enhance cathodic HER. The FOR-HER system Au–CuxO/CF∥Ru–CuxO/CF was tested flow cell. produced current density 500 mA cm–2 only 0.38 V. This work provides construction catalyst design ideas voltages.

Spherical heterojunction nanocomposite materials are utilized to treat wound infections caused by drug-resistant bacteria synergistically generating reactive oxygen species (ROS) and multiple cations (multiple inorganic or organic ions with positive points). However, there is an ongoing debate on the relative contributions of ROS towards antibacterial activity. With aim investigating activity, this study synthesized CuFe2O4/Cu@PEI/Ag (ZPA) nanocomposites release abundant •O2-, •OH, Fe3+, Cu2+, Ag+, polyethyleneimine (PEI). The results revealed that after 25 min, at a concentration 40.8 μg/mL, material exhibited inhibition rate over 99.99% against Staphylococcus aureus (S. aureus) methicillin-resistant S. (T- aureus). This activity could be attributed (Fe3+, Ag+ PEI) in following order: > •O2- •OH single cation. potential mechanism involved synergy mechanisms: Leakage cytoplasmic content due damage bacterial cell wall alteration secondary structure bound via electrostatic attraction. By healing T - aureus-induced infection completely eliminating burden 11 days ZPA also effectively polarized M1 type macrophages M2 vivo. Thus, findings elucidate combined effect free radicals properties composite materials. indicate holds clinical for treating infections.
