Advanced surface engineering for the nickel-rich cathode materials greatly enhances structural/thermal stability. However, their application into the lithium-ion full-cell have still challenge such as unstable solid electrolyte interphase (SEI) layer on the a...

Activation of Ultrathin SrTiO3 with Subsurface SrRuO3 for the Oxygen Evolution Reaction

Water electrolysis occurs via the oxygen/hydrogen evolution reactions1,2. Achieving sufficiently high oxygen evolution reaction (OER) activity while maintaining stability of the active catalyst surface is a primary challenge of designing OER catalysts1,3. Oft...

Cadmium-free CuInS2/ZnS quantum dots as efficient and robust photosensitizers in combination with a molecular catalyst for visible light-driven H2 production in water

2018-04-10

We demonstrate that cadmium-free core–shell CuInS2/ZnS quantum dots (QDs) are very efficient and robust visible-light absorbing photosensitizers for photocatalytic hydrogen production in a fully aqueous solution when associated with a molecular catalyst, a co...

Synergism induced exceptional capacity and complete reversibility in Mg-Y thin films: enabling next generation metal hydride electrodes

10.1039/C7EE03628K

2018-04-09

Much of current research in metal hydride (MH) electrodes follows the principle that the materials should be composed of hydrogen-absorbing elements (A) and non-hydrogen-absorbing elements (B). This classical design principle, however, severely limits the pot...

Solid-State-Ligand-Exchange Free Quantum Dot Ink-based Solar Cells with Efficiency of 10.9%

2018-04-06

While colloidal quantum dot based solar cells (CQDSCs) have recently achieved power conversion efficiencies (PCE) up to 11.3%, the CQD active layers are fabricated almost exclusively by a combined process of in-situ solid-state ligand exchange (SSE) with mult...

Pd@TiO2/Carbon Nanohorns electrocatalysts: Reversible CO2 hydrogenation to formic acid

2018-04-06

Direct conversion of carbon dioxide to formic acid at thermodynamic equilibrium is a privilege of enzymatic catalysis, hardly replicated by synthetic analogs, but of high priority for carbon-neutral energy schemes. The bio-mimetic potential of totally inorgan...

Spatial Control of Cocatalysts and Elimination of Interfacial Defects towards Efficient and Robust CIGS Photocathodes for Solar Water Splitting

2018-04-06

Chalcopyrite thin film absorbers such as Cu(In,Ga)Se2 (CIGS) exhibit excellent solar energy conversion efficiency, particularly when coupled with CdS to form an excellent p-n junction. To advance CIGS towards efficient photoelectrochemical (PEC) hydrogen evol...

Unsymmetrical fluorinated malonatoborate as an amphoteric additive for high-energy-density lithium-ion batteries

2018-04-06

High-capacity Si-embedded anodes and Li-rich cathodes are considered key compartments for post lithium-ion batteries with high energy densities. However, the significant volume changes of Si and the irreversible phase transformation of Li-rich cathodes preven...
