P‐doped MoS2/Ni2P/Ti3C2Tx heterostructures for efficient hydrogen evolution reaction in alkaline media
By combining the advantages of doping to change the electronic structure of molybdenum disulfide (MoS2), transition metal phosphides, and MXene, we proposed the idea of designing and preparing a new type of composite material, P‐doped MoS2/Ni2P/Ti3C2Tx heterostructures (denoted as P@MNTC), to serve...

| description | By combining the advantages of doping to change the electronic structure of molybdenum disulfide (MoS2), transition metal phosphides, and MXene, we proposed the idea of designing and preparing a new type of composite material, P‐doped MoS2/Ni2P/Ti3C2Tx heterostructures (denoted as P@MNTC), to serve as the hydrogen evolution reaction (HER) catalyst of electrochemical water splitting. The as‐prepared P@MNTC heterostructures show a significant HER activity with an overpotential of 120 mV at 10 mA cm–2 in alkaline electrolyte, with decreasing 105 and 125 mV compared with those of MoS2 and MXene, respectively. The density functional theory indicates that the P doping and synergy effect of Ti3C2Tx can enhance the activation of MoS2 and thus promote dissociation and absorption of H2O during HER process. This strategy provides a promising way to develop high‐efficiency MoS2‐ and Ti3C2Tx‐based composite catalysts for alkaline HER. |
