Study of electrochemical and photoelectrochemical properties of nickel phosphide semiconductors

2-Photon tandem device for water splitting: comparing photocathode first versus photoanode first designs

“…Another abundantly available H 2 evolution catalyst, Ni 2 P, 81 is also a semiconductor with a bandgap near 1.0 eV and a conduction band near the H 2 evolution potential. 82,83 While yet untested, this also may have the potential to act as a dual function protection layer/H 2 evolution catalyst. A special advantage in having a dual function protection layer/catalyst is that even if this layer corrodes at a manageable rate ($1 monolayer per month), a thick layer may still allow continued catalytic activity even as the protection layer slowly corrodes.…”

Deposition of phase pure nickel sulfide thin films from bis(O-alkylxanthato)–nickel(II) complexes by the aerosol assisted chemical vapour deposition (AACVD) method

“…It is a p-type semiconductor with a narrow band gap (0.5 eV) finds applications in cathode materials for rechargeable lithium batteries [6], catalysts [7,8], IR detectors [9], and sensors [10] as well as photoelectrochemical and solar cells [11,12].…”

Photocatalytic hydrogen generation from a visible-light responsive metal–organic framework system: the impact of nickel phosphide nanoparticles

“…In terms of thermodynamics of electron transfer, from the energy diagram (Fig. S22), the conduction band of Ni2P has a lower reduction potential (Evac.= -4.50 eV) 46 than the LUCOs of MIL-125-NH2 (Evac.= -3.80 eV), and is in the same level as the reduction potential of H + /H2 (Evac.= -4.50 eV, ENHE= 0 eV). 43 This large negative energy difference between MIL-125-NH2 and Ni2P stems from the discrete Ti8O8 cluster on MIL-125-NH2 being exceptionally reducing.…”
