Single atom catalysts offer a promising approach for CO₂ electroreduction to CO, but achieving high efficiency remains challenging. Here, the authors report lanthanide single atom catalysts with the transition ability from bridge to linear adsorption that exhibit efficient CO production.

Manipulating the carbon-carbon coupling pathway in CO₂ electroreduction is vital yet challenging. Here, by studying two model copper-based catalysts with distinct ethylene and ethanol selectivity, authors investigate the mechanistic origins for symmetric and asymmetric carbon-carbon coupling.

A versatile hydrothermal approach in an operando acidic environment created ferromagnetic single-atom spin catalysts (SASCs). Ni-based SASC exhibits a giant magnetic field enhancement of OER activity, boosting both water and saline water electrolysis.

Conversion into high-value-added organic nitrogen compounds through electrochemical C-N coupling reactions is considered a sustainable strategy to achieve carbon neutrality. Herein, we report the selective electrosynthesis of formamide from carbon monoxide and nitrite using Ru₁Cu single-atoms catalyst.

Electrocatalytic nitrite reduction is a green alternative to the Haber-Bosch process, but its ammonia production remains inefficient at low nitrite levels. Here the authors report an intermetallic single atom alloy CuZn catalyst for nitrite reduction to ammonia with high efficiency and stability at low nitrite concentration of 1−10 mM.

Designing stable Ru-based catalysts for acidic oxygen evolution remains a challenge. Here, the authors propose an oxyanion protection strategy to prevent the formation of oxygen vacancies on the RuO₂ surface by creating coordination-saturated lattice oxygen, thereby greatly enhancing the stability.

Electrocatalytic alkyne semi-hydrogenation to alkenes is challenging due to the hydrogen evolution competing reaction and over-hydrogenation. Here, the authors report Cu50Au50 alloy for high selectivity towards styrene production.

Hydroxyl radicals are reactive species capable of water purification and disinfection, although their generation, particularly through renewable approaches, is challenging. Now, low-valent Au on potassium-incorporated carbon nitride has been shown to produce hydroxyl radicals upon solar illumination and to provide high water disinfection rates.

Metal borides/borates are promising candidates to become high-performance alkaline oxygen evolution reaction catalysts. This study reports an in-situ phase composition modulation approach to fabricate boride/borate-based catalysts.

Interim analysis from the randomized phase 3 JUPITER-02 trial shows that the addition of anti-PD-1 toripalimab to standard gemcitabine/cisplatin as a first-line treatment for patients with recurrent or metastatic nasopharyngeal carcinoma has manageable toxicity and improves progression-free survival, suggesting a potential new treatment standard in this setting.

Electroreduction of CO₂ on single atom catalysts is often hindered by electron delocalization of the metal sites. To improve CO₂ activation, here the authors functionalize the carbon support with cyano moieties, thereby attenuating metal-substrate conjugation and improving CO₂ to CO conversion.

Hydrogen peroxide is an interesting target for artificial photosynthesis, although its actual production via the two-electron oxygen reduction reaction remains limited. Now, a carbon nitride-supported antimony single atom photocatalyst has been developed with a superior performance for this process.

Direct observation of the atomic and electronic structure of a single-atom catalyst is essential. Here, the authors report an oxyhydroxide stabilized iridium catalyst with superior oxygen evolution catalytic activity and identify the isolated iridium sites which promote the H₂O attack and O–O coupling.

Iron phthalocyanine with a 2D structure and symmetric electron distribution around Fe-N₄ active sites is not optimal for O₂ adsorption and activation. Here, the authors report an axial Fe–O coordination induced electronic localization strategy to enhance oxygen reduction reaction performance.

The modulation of single-atom catalyst properties for industrial applications remains challenging. Here, authors use strain engineering to amplify the synergistic effect between MoS₂’s sulphur vacancies and single-atom Ru sites and accelerate H₂ evolution electrocatalysis.

While water splitting chemistry provides a renewable means to produce carbon-neutral hydrogen fuel, the most efficient catalysts require rare and expensive platinum. Here, authors prepare single-atom platinum on cobalt selenide as a high-performance hydrogen evolution electrocatalyst.
