Metallic-State SnS<sub>2</sub> Nanosheets with Expanded Lattice Spacing for High-Performance Sodium-Ion Batteries

25 luglio, 2019 - 00:00

Bloating, but the good kind: Intercalation of Ni into SnS2 results in 2D nanosheets with expanded lattice spacing and a defect-rich structure, resulting in a change in electron density and energy band structure. The resulting electrode structure, composed of vertically aligned nanosheets, exhibits shorter paths for ion insertion and extraction, larger contact area for more diffusion pathways, and superior electrolyte penetration.

Fluoridated Iron-Nickel Layered Double Hydroxide for Enhanced Performance in the Oxygen Evolution Reaction

25 luglio, 2019 - 00:00

Boosted by fluorination: The temperature dependence of the crystal structure and surface chemical state for simple fluoridation of an iron-nickel layered double hydroxide (LDH) is demonstrated for the electrochemical oxygen evolution reaction. The improved performance can be mainly attributed to the phase-structure transfer from metal−O bonding in the FeNi-LDHs to metal−F bonding after fluoridation.

Selective Cellulose Hydrogenolysis to Ethanol Using Ni@C Combined with Phosphoric Acid Catalysts

25 luglio, 2019 - 00:00

Cellulose conversion into ethanol: Ethanol is obtained through one-pot cellulose hydrogenolysis over graphene-layers-encapsulated nickel catalysts with the aid of H3PO4 in water. This work, for the first time, demonstrates a chemocatalytic approach for a high-yield production of ethanol from biomass using a non-noble metal catalyst.

Positive Surface Pseudocapacitive Behavior-Induced Fast and Large Li-ion Storage in Mesoporous LiMnPO<sub>4</sub>@C Nanofibers

25 luglio, 2019 - 00:00

Lithium storage: One-dimensional (1D) LiMnPO4@C nanofibers with in situ-created 3D mesoporous architecture are reported, and the charge-storage behavior is addressed. Remarkably, the hierarchical construction promotes the pseudocapacitive contributions. The diffusion-controlled battery-type and surface-controlled capacitive faradaic redox processes act synergistically, giving new insights into Li-storage cathode materials to reach the goal of high energy and power densities simultaneously.

Photocatalytic Oxygenation Reactions Using Water and Dioxygen

25 luglio, 2019 - 00:00

As green as it gets: Water (H2O) is the most environmentally benign reductant and is oxidized to evolve dioxygen (O2)—the greenest oxidant—in photosystem II. This Minireview focuses on photocatalytic oxygenation of substrates with H2O as an oxygen source and O2 as an oxidant.
