Defect Mediated Improvements in the Photoelectrochemical Activity of MoS/SnS Ultrathin Sheets on Si Photocathode for Hydrogen Evolution.

Solar-driven water electrolysis to produce hydrogen is one of the clean energy options for the current energy-related challenges. Si as a photocathode exhibits a large overpotential due to the slow hydrogen evolution reaction (HER) kinetics and hence needs to be modified with a cocatalyst layer. MoS is a poor HER cocatalyst due to its inert basal plane.

Peaks in the synchrotron X-ray diffraction (SXRD) data show a systematic shift toward smaller angles due to the introduction of the larger Ba cation in the same crystal structure.

Improvement of lithium anode deterioration for ameliorating cyclabilities of non-aqueous Li-CO batteries.

Herein, ruthenium (Ru) nanoparticles were anchored on carbon nanotubes (Ru/CNTs) functionalized as catalyst cathodes for non-aqueous Li-CO cells. For cycling tests through a low cut-off capacity (100 mA h g), the origin of battery deterioration resulted from the accumulation of LiCO discharging products on catalytic surfaces, identical to the observations in previous studies. However, the Li-CO cells in this work showed a sudden death within several cycles of high cut-off capacity (500 mA h g), and no LiCO residues were investigated on the cathode.
