Summary: This method involves the large-scale fabrication of bowl-shaped colloidal particles using an emulsion templating technique, where compliant seed particles are deformed by surface tension on oil droplets as templating surfaces. By adjusting droplet size and seed particle diameter, the final particle shape can be precisely controlled, ranging from shallow lenses to deep bowls. The resulting uniformly-shaped colloidal particles allow for depletion-mediated assembly of flexible colloidal chains and clusters.

Summary: A facile approach of introducing ultrasound for the large-scale rapid synthesis of core-shell C@MnO2 nanoparticles was suggested. The mesoporous C@MnO2 particles possess a high specific surface area of 62.8 m(2) g(-1). The stable gel electrolyte enabled the C@MnO2 electrode to deliver a specific capacitance of 177 F g(-1) at 0.5 A g(-1) under a high mass loading and a specific capacitance of 128 F g(-1) at 10 A g(-1) current density. Long-term test confirmed the practical application of MnO2 for energy storage devices, with only an 8.3% decline in initial capacitance after 5000 cycles.

Summary: Carbon supported single atom catalysts (SACs) have shown great potential as effective electrocatalysts in energy storage and conversion devices. This research demonstrates that by controlling the layers of single atom active sites, the catalysts exhibit enhanced activity in the oxygen reduction reaction (ORR), leading to higher turnover frequency (TOF) and reducing the reaction overpotential. The newly-developed catalysts with sublayer-enhanced active sites also show significantly improved performance in alkaline and acidic conditions, making them promising for applications in Zn-air batteries and fuel cells.

Summary: Carbon nanotubes provide a stable platform for studying oxygen evolution reaction (OER) mechanisms under different pH conditions. The study reveals that OER on carbon nanotubes is primarily constrained by water deprotonation in acidic and neutral conditions, but shifts to a different mechanism and kinetics in alkaline conditions due to competition discharge between hydroxide ions and water.

Summary: Effective capture and utilization of CO2 is critical for reducing greenhouse gas emissions and achieving a low-carbon economy. In this study, bismuth oxides with different crystallized phases (alpha, beta, delta, gamma) were synthesized and used as photo, thermal, and photothermal catalysts for the carbonylation of isobutyl amine with CO2. The results showed that the alpha-Bi2O3 exhibited the highest catalytic performance, with a conversion of 50.38% and a selectivity of 91.79% for N,N'-diisobutylurea. Further characterization of Bi2O3 polymorphs revealed that the differences in photothermal catalytic activity could be attributed to the efficiencies of photoinduced carriers separation.

Summary: The article explores the importance of mass transfer in catalytic processes, specifically in the electrocatalytic oxygen reduction reaction (ORR) by tailoring the pore sizes. By employing a confined-etching strategy, boron-and nitrogen-doped carbon (B,N@C) electrocatalysts with abundant active sites but different porous structures were fabricated. The ORR performance was found to be correlated with reactant diffusion, with the optimized B,N@C catalysts featuring trimodal-porous structures demonstrating enhanced O2 diffusion and improved activity per heteroatomic site. The study highlights the significance of nanoarchitecture engineering in catalysts and provides insights into optimizing structures with abundant active sites and enhanced mass transfer.

Summary: In this paper, the authors study the characteristics of chromium evaporation, oxide scale growth, and deposition of chromium on the oxygen reduction reaction (ORR) on (La,Sr)MnO3 (LSM) cathode in intermediate-temperature solid oxide fuel cells. The results indicate that the volatilization of chromium is influenced by the composition and morphology of the oxide scale, and the deposition of chromium on the LSM cathode degrades the electrochemical activity of the ORR. These findings provide insights into the mechanism of chromium poisoning in intermediate-temperature conditions.

Summary: Despite progress in sustainable ammonia technology, the efficiency and yield of artificial nitrogen fixation under ambient conditions remain low. In this study, a bifunctional catalyst called CQDs/STO, consisting of ultrathin carbon quantum dots and hydrogenated mesoporous SrTiO3 heterostructure, has been developed to enhance nitrogen reduction. The CQDs/STO catalyst exhibits high photocatalytic activity and achieves an ammonia yield of 143 mu mol g(-1) h(-1) without sacrificial reagents, which is about 7 times higher than STO nanoparticles. Furthermore, the CQDs/STO catalyst can also be used for cascade photoelectrochemical nitrogen reduction, resulting in a 50% increase in ammonia yield. Density functional theory calculations reveal the synergy between SrTiO3 and CQDs, with the oxygen vacancies in SrTiO3 playing a key role as electrocatalytic centers. This cascade catalytic system provides new insight into designing solar-driven nitrogen fixation devices.
