Au Species Boost the Catalytic Performance of Au/ZnO for the Semi-hydrogenation of Acetylene.

Au nanoparticles have garnered remarkable attention in the chemoselective hydrogenation due to their extraordinary selectivity. However, the activity is far from satisfactory. Knowledge of the structure-performance relationship is a key prerequisite for rational designing of highly efficient Au-based hydrogenation catalysts.

Carbon/Polymer Bilayer-Coated Si-SiO Electrodes with Enhanced Electrical Conductivity and Structural Stability.

Si-based electrodes offer exceptionally high capacity and energy density for lithium-ion batteries (LIBs),but suffer from poor structural stability and electrical conductivity that hamper their practical applications. To tackle these obstacles, we design a C/polymer bilayer coating deposited on Si-SiO microparticles. The inner C coating is used to improve electrical conductivity.

Bi-functional nitrogen-doped carbon protective layer on three-dimensional RGO/SnO composites with enhanced electron transport and structural stability for high-performance lithium-ion batteries.

Three-dimensional reduced graphene oxide@SnO@nitrogen-doped carbon (3DG@SnO@N-C) composites are designed as high efficiency anode materials for lithium-ion batteries. The SnO particle size, surface area and pore size distribution of the 3DG@SnO@N-C could be simply controlled by altering the GO dosages. The optimized 3DG@SnO@N-C electrode demonstrates a reversible capacity of 1349.

Hollow K0.27MnO2 Nanospheres as Cathode for High-Performance Aqueous Sodium Ion Batteries.

Hollow K0.27MnO2 nanospheres as cathode material were designed for aqueous sodium ion batteries (SIBs) using polystyrene (PS) as a template. The samples were systematically studied by X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy.
