Summary: Adding other transition metals into Pd lattice is an effective strategy to improve Pd utilization and enhance its catalytic activity through generated ligand and strain effects. In this study, PdMn nanosheet assembled nanobuds were synthesized using a facile method, which showed significantly better catalytic activity and stability compared to the-state-of-the-art Pd-C catalyst. The catalytic enhancement mechanism can be mainly attributed to the modulated electronic structure and consequent charge redistribution that resulted in the generated ligand effect.

Summary: This study presents an effective method to enhance the durability of metallic Pd electrocatalyst for formic acid oxidation reaction (FAOR) by alloying with Cu and Au. The alloying process improves CO resistance and reduces Pd and Cu dissolution, while also modulating the electronic structure of Pd for better FAOR performance. The nanoporous PdCuAu ternary alloy catalyst exhibits significantly higher specific activity and mass activity compared to commercial Pd/C, resulting in a remarkable increase in power density and power efficiency for fuel cell applications.

Summary: In this study, bismuth-based catalysts were introduced for the efficient electrochemical reduction of CO2 to formic acid. The catalysts consisted of petal-shaped Bi2O2CO3 (BOC), which spontaneously formed from Bi thin film in aqueous carbonate solution at room temperature. The BOC petals transformed to reduced BOC (R-BOC) during the electrochemical reduction process, and the lattice mismatch between the domains induced strain at the interfaces. The R-BOC petals exhibited a superior Faradaic efficiency of 95.9% for the electrochemical conversion of CO2 to formic acid.

Summary: This study demonstrates with experimental evidence how the emulation of space-time symmetry breaking by electrochemical realization of a Time-Gel' can lead to the creation of matter. Time-Gel' is realized by inducing the gelation phenomenon of discrete molecular precursors, and the temporal information descriptor (Q) exhibits a power-law relationship (Q proportional to Phi(g)^n) with the volume fraction of the gel (Phi(g)). The exponent n is 5, indicating the divergence in matter creation. This finding further supports the understanding that the breaking of symmetry under conditions following Noether's theorem leads to the emergence of matter. In summary, this research proposes the idea of symmetry breaking and presents the electrochemical realization of the Time-Gel' model as an alternative explanation for the creation of matter based on Chemical Science.
