Summary: In this study, a highly efficient three-dimensional hybrid of anions (Cl- and CO32-) doped cobalt hydroxide catalyst coupled with nitrogen-doped carbon dots (Co(OH)2@NCDs) was reported for oxygen evolution reaction. The well-defined urchin-like Co(OH)2@NCDs composite exhibited superior OER performance with low overpotential and high durability in KOH solution. The coupling of NCDs in the Co(OH)2 hybrid generated a new Co-N charge transfer channel and optimized electronic environment, improving electron transfer and enhancing OER kinetics.

Summary: This study investigates the deactivation mechanism of N-doped carbon materials in the oxygen reduction reaction (ORR) through experiments and computational modeling. It reveals that in both acidic and alkaline environments, graphitic-type nitrogen species deactivate through oxidation and tautomerization reactions, resulting in the formation of N-C-O-type groups, which affect the catalytic activity.

Summary: The Fe-N-C catalyst prepared using 2,6-diaminopyridine and FeCl3 displayed excellent catalytic activity for the oxygen reduction reaction (ORR), outperforming commercial Pt/C catalyst in an alkaline medium. With rich pyridinic nitrogen, graphitic nitrogen, and Fe-N-x species as active sites, the catalyst showed an onset potential of about 0.96 V, a half-wave potential of about 0.84 V, and a limiting current density of 5.8 mA cm(-2), with superior stability compared to Pt/C. This work provides a strategy for synthesizing universal M-N-C catalysts.

Summary: We demonstrated a facile pyrolysis method for synthesizing nitrogen-doped carbon-supported NiFe alloys (NiFe-NC) that exhibit excellent electrocatalytic activity for both CO2 reduction reaction (CO2RR) and oxygen reduction reaction (ORR). The NiFe-NC catalyst showed unprecedented CO2RR activity with a high CO faradaic efficiency and achieved a industrial current density and CO FE comparable to commercial catalysts for CO2RR. It also demonstrated impressive ORR performance comparable to commercial Pt/C catalysts. Moreover, the NiFe-NC was successfully used as a cathode material in Zn-air batteries and showed high power density. A self-driven CO2 flow electrolysis system powered by two series-connected NiFe-NC-based Zn-air batteries was designed and showed high efficiency in converting CO2 to CO. The results of this study provide insights for the development of efficient electrocatalysts for energy conversion and storage.

Summary: The use of 3D porous wrinkled graphitic carbon (PWGC) as the carbon support in proton-exchange membrane fuel cells improves their durability and stability. The PWGC, synthesized using a catalyst-free, plasma-enhanced chemical vapor deposition approach, possesses a high surface area, a high degree of graphitization, and exceptional corrosion resistance. Pt/PWGC catalysts demonstrate superior high potential stability compared to those made with commercial carbon supports, and Pt@C/PWGC catalysts show significantly improved durability with the introduction of a sacrificial layer strategy.

Summary: This study aimed to assemble biomimetic 3D BM microniches by co-culturing HSPCs and MSCs, and transplant them into the BM cavity for the treatment of h-ARS. The results showed that these BM microniches can prolong the maintenance of HSPCs, promote hematopoietic reconstitution, and alleviate death from acute lethal radiation. Furthermore, the Notch signaling pathway plays a significant role in maintaining HSPCs.

Summary: By comparing PtCo catalysts with different ordering degrees but the same alloying degree, we determined that the ordering effect increases the ORR activity by approximately 1.5 times. The highly ordered PtCo intermetallic catalyst is prepared by separating the alloying and ordering stages, while the disordered counterpart with the same alloying degree is obtained by quenching the ordered catalyst at high temperatures to freeze the random atomic arrangement. Experimental and theoretical studies reveal that both the alloying effect and ordering effect of intermetallic alloy catalysts originate from the compressive strain effect, which weakens the adsorbate bonding towards oxygen-containing adsorbate and promotes ORR kinetics.

Summary: Fully exposed cluster catalysts (FECCs) with multiple metal atoms provide a bridge between single-atom catalysts (SACs) and nanoparticles (NPs). While FECCs have been extensively studied in dehydrogenation and oxidation reactions, their application in hydrogenation is limited. This study shows that fully exposed Ir clusters anchored on sulfur-doped carbon support exhibit higher activity and stability in the hydrogenation of N-heteroarenes compared to Ir SAC and Ir NPs catalysts. The reaction mechanism on Irn/SC is also elucidated.

Summary: Scalable low-Pt PtCu3 intermetallic oxygen reduction electrocatalysts were synthesized with the assistance of sulfur-containing inorganic salts. The success of the catalyst synthesis relies on the use of inorganic negative bivalent sulfur salts, which form a CuS2 intermediate at low temperatures and facilitate the formation of PtCu3 intermetallic catalyst at high temperatures. The prepared small-sized PtCu3 intermetallic catalyst exhibits high mass-based activity (3.0 A mg(Pt) (-1)), large electrochemically active surface area (74 m(2) g(Pt) (-1)) for oxygen reduction, and outstanding durability (18% mass activity loss after 30,000 cycles).

Summary: We investigated the effects of wet-impregnation and oleylamine-mediated colloid methods on the synthesis of PtCo intermetallic catalysts on different porous carbon supports. It was found that efficient utilization of the internal surface area of porous carbon supports is crucial for the synthesis of small-sized PtCo intermetallic catalysts, which is highly dependent on the metal deposition method and the pore structure of the carbon supports. As a result, small-sized PtCo intermetallic catalysts with enhanced oxygen reduction reaction activity and improved proton exchange membrane fuel cell performance were prepared using the wet-impregnation method on mesoporous carbon supports.

Summary: In this study, a cuprous sulfide (Cu1.96S) intermediate-assisted strategy is demonstrated for the scalable synthesis of PtCu3 intermetallic electrocatalysts on an S-doped carbon black support. It is found that the Cu1.96S intermediate formed at low temperature gradually releases metallic Cu species at high temperatures to form a small-sized and uniform Pt-Cu alloy with target stoichiometry, ensuring the formation of well-ordered intermetallic PtCu3 structures. The prepared intermetallic PtCu3 catalysts exhibit enhanced ORR performance with a mass activity of 3.2 A mg(Pt)(-1) and retain 72% of the initial activity after durability tests.

Summary: By using high-temperature X-ray diffraction and energy-dispersive spectroscopic elemental mapping techniques, we studied the formation process of IMCs, particularly PtCo, in an industrial impregnation synthesis. We found that high-temperature annealing is crucial for promoting the formation of alloy particles with a stoichiometric Co/Pt ratio, leading to the transformation of disordered alloys into ordered intermetallic structures at low temperatures. Based on these findings, we successfully synthesized highly ordered L1(0)-type PtCo catalysts with remarkable ORR performance in fuel cells.
