Manipulation C-C coupling pathway is of great importance for selective CO electroreduction but remain challenging. Herein, two model Cu-based catalysts, by modifying Cu nanowires with Ag nanoparticles (AgCu NW) and Ag single atoms (AgCu NW), respectively, are rationally designed for exploring the C-C coupling mechanisms in electrochemical CO reduction reaction (CORR). Compared to AgCu NW, the AgCu NW exhibits a more than 10-fold increase of C selectivity in CO reduction to ethanol, with ethanol-to-ethylene ratio increased from 0.

Realizing an efficient turnover frequency in the acidic oxygen evolution reaction by modifying the reaction configuration is crucial in designing high-performance single-atom catalysts. Here, we report a "single atom-double site" concept, which involves an activatable inert manganese atom redox chemistry in a single-atom Ru-Mn dual-site platform with tunnel Ni ions as the trigger. In contrast to conventional single-atom catalysts, the proposed configuration allows direct intramolecular oxygen coupling driven by the Ni ions intercalation effect, bypassing the secondary deprotonation step instead of the kinetically sluggish adsorbate evolution mechanism.

The poor durability of Ru-based catalysts limits the practical application in proton exchange membrane water electrolysis (PEMWE). Here, we report that the asymmetric active units in RuMO (M = Sb, In, and Sn) binary solid solution oxides are constructed by introducing acid-resistant p-block metal sites, breaking the activity and stability limitations of RuO in acidic oxygen evolution reaction (OER). Constructing highly asymmetric Ru-O-Sb units with a strong electron delocalization effect significantly shortens the spatial distance between Ru and Sb sites, improving the bonding strength of the overall structure.

Article Synopsis
  • Active sites in Ru-based catalysts for proton-exchange membrane water electrolyzers (PEMWE) face challenges due to continuous oxidation and leachability, limiting their practical use.
  • The study proposes the use of inter-doped tungsten-ruthenium oxide heterostructures [(Ru-W)O], which enhance the performance and stability of the oxygen evolution reaction (OER) in acidic environments by promoting valence oscillation in Ru sites.
  • The developed heterostructures show impressive results, with a low overpotential of 170 mV at 10 mA cm and maintaining operation for 300 hours in acidic electrolytes, indicating strong potential for real-world applications in PEMWE.

Single-atom catalysts exhibit superior CO -to-CO catalytic activity, but poor kinetics of proton-coupled electron transfer (PCET) steps still limit the overall performance toward the industrial scale. Here, we constructed a Fe-P atom paired catalyst onto nitrogen doped graphitic layer (Fe /PNG) to accelerate PCET step. Fe /PNG delivers an industrial CO current of 1 A with FE over 90 % at 2.

Article Synopsis
  • Scientists are looking for better ways to turn carbon dioxide (CO) into methane (CH), which is a useful energy source that can fit into what we already have in terms of energy systems.
  • Current methods lose some CO during the process, making it hard to get it back without using too much energy.
  • By using special chemicals to hold onto copper ions, they found a way to create methane more efficiently in acidic conditions, achieving a 71% success rate while losing very little CO.*

In this study, vitrification was applied to treat Ni-Cu electroplating sludge. The sludge was mixed with additives (limestone:cullet = 4:6) and then heated to 1450 °C. The cooled product could be separated into slag and ingot.
