Nowadays, searching for the effective hydrogen (H2) storage/ generation materials remains one of the most difficult challenges toward a fuel-cell-based H2 economy as a longterm solution for secure energy in future. Formic acid (FA, HCOOH), a major product of biomass processing with highenergy density, nontoxicity, and excellent stability at room temperature, has recently attracted tremendous re...
The realization of high-efficiency, reversible, stable, and safe Li-O2 batteries is severely hindered by the large overpotential side reactions, especially at high rate conditions. Therefore, rational design cathode catalysts with activity stability crucial to overcome terrible issues current density. Herein, we report a surface engineering strategy adjust electron structure boron (B)-doped PtN...
Alloy nanoparticles (nanoalloys) are widely applied in heterogeneous catalysts, advanced electrodes, biomaterials, and other areas. The properties of nanoalloys can be tuned to a significant extent by their structures compositions, which governed the employed synthetic procedure. Often such synthesis occurs non-equilibrium conditions yields with that different from those obtained thermodynamic ...
Highly active, supported Au−Pd catalysts have been tested for catalyzing benzyl alcohol oxidation in a siliconglass micropacked bed reactor. The effects of Au−Pd composition and anion content during catalyst preparation on catalyst deactivation were studied, and a relationship between the deactivation rate and the amount of Cl− and Au used in the catalyst formulation was found. While Au aids in...
The global optimisation of small bimetallic PdCo binary nanoalloys are systematically investigated using the Birmingham Cluster Genetic Algorithm (BCGA). The effect of size and composition on the structures, stability, magnetic and electronic properties including the binding energies, second finite difference energies and mixing energies of Pd-Co binary nanoalloys are discussed. A detailed anal...
