Summary: By combining the advancements in electronic spin state modulation and tandem reaction mechanism, a dual iron-copper catalyst is designed at the atomic level to enhance oxygen reduction capability. The catalyst achieves intense interaction between the iron-copper site and its coordination environment, which not only controls charge flow at the atomic level, but also regulates electron configuration. These modulations optimize orbital interaction and pair hardness between acceptor and donor, resulting in fast tandem reaction kinetics that overcomes the limitations of Scaling Relation. The bimetal catalyst demonstrates high activity and stability in oxygen reduction, even outperforming the benchmark Pt/C in pH-universal electrolytes. Furthermore, Fe,Cu/N-C driven Zn-air batteries show excellent performance in alkaline and neutral electrolytes. This work provides a useful design principle for developing or optimizing other efficient oxygen reduction catalysts.

Summary: This study fabricates a Cu/Ga-MFI catalyst with well-dispersed framework Ga species and achieves high selectivity for aromatics production. The Ga atoms in the MFI framework create a moderate acid strength, while the introduced Cu provides an appropriate acid distribution, enhancing the synergy between metal-related species and the zeolite. Additionally, DFT simulation results suggest that the acid sites in Ga-MFI are more preferable for propane dehydrogenation. Furthermore, CO2 can inhibit coke formation, endowing Cu/Ga-MFI catalyst with excellent anti-coking ability and regeneration stability.

Summary: Our study presents a comprehensive approach for the selective oxidation of glucose to glucaric acid (GA) by heterogeneous catalysis. We synthesized and characterized Au/ZrO2, AuCu/ZrO2, and AuPt/ZrO2 catalysts and found that bimetallic catalysts form alloys, which exhibit different characteristics than monometallic counterparts. We also constructed a predictive microkinetic model and found that AuPt/ZrO2 showed the highest selectivity. These results provide valuable insights for the developing of efficient catalysts and point out the bottlenecks for the oxidation of glucose to GA.

Summary: In this study, the synergistic effect between argon-plasma-system (AP) and catalysts in promoting the production of reactive species for water remediation was investigated. By altering the oxygen vacancies concentration of CeO2/Bi2O3 catalyst, the production of hydrated electrons was stimulated for PFOA removal. The results showed that the built-in electric field in the Bi/Ce0.43 interface enhanced electron migration and eaq- generation, leading to improved PFOA removal efficiency.

Summary: One major barrier in solvent-based CO2 capture for industrial applications is the high energy consumption required for absorbent regeneration. This study proposed a novel multi-stage circulation (MSC) CO2 absorption process that independently regulated each stage, resulting in improved CO2 capture performance and reduced CO2 regeneration duty. Experimental results showed that the MSC process significantly reduced CO2 regeneration duty and achieved energy consumption reduction using NH3/K2CO3 solution.
