    • Exploring high-efficient oxygen evolution reaction (OER) catalysts is critical for producing clean H-2 fuel through water splitting. Co and P involved Co-Pi and cobalt phosphide OER catalysts attracted tremendous attention, while limited report on cobalt phosphite as an OER catalyst. Herein, a novel cobalt phosphite nanowires with microporous 1D channel have been succsessfully discovered with remarkable catalytic performance of a low overpotential of (similar to)340 mV and Tafel slope of 60 mV dec(-1) at 10 mA cm(-2) at pH 14. Through comprehensive structural characterization, the effective species has been clearly illustrated to be the in-situ formed heterostructural Co-11(HPO3)(8)(OH)(6)/Co-11(PO3)(8)O-6 core-shell structure nanowires. This work fills the gap for exploring high efficient cobalt phosphites OER catalysts under akaline condition and paves the way for exploring novel high efficiency waster splitting catalysts.

  • Faraday Rotation Due to Surface States in the Topological Insulator (Bi1-xSbx)(2)Te-3
  • 2017
  • Ingår i: Nano letters (Print). - : American Chemical Society (ACS). - 1530-6984 .- 1530-6992. ; 17:2, s. 980-984

    • Using magneto-infrared spectroscopy, we have explored the charge dynamics of (Bi,Sb)(2)Te-3 thin films on InP substrates. From the magneto-transmission data we extracted three distinct cyclotron resonance (CR) energies that are all apparent in the broad band Faraday rotation (FR) spectra. This comprehensive FR-CR data set has allowed us to isolate the response of the bulk states from the intrinsic surface states associated with both the top and bottom surfaces of the film. The FR data uncovered that electron- and hole-type Dirac Fermions reside on opposite surfaces of our films, which paves the way for observing many exotic quantum phenomena in topological insulators.
