For the first time, PdP has been synthesised using a simple, straightforward and one-pot method , thermolysis of a Pd(II) complex of a bidentate (P, N) organophosphorus ligand (anthracene-9-yl-CHN-CHCH-PPh). The electrocatalyst (obtained after grafting nanospheres of PdP over layers of graphene oxide) shows high activity in electrochemical hydrogen evolution reactions (HER) with an overpotential of 133 mV to drive 10 mA cm of cathodic current density. The GO-PdP nanocomposite is robust and effective for a continuous HER run for up to 16 hours.
首次使用一种简单、直接的一锅法合成了PdP，即对双齿（P，N）有机磷配体（蒽-9-基-CH₂N-CH₂CH-PPh）的钯（II）配合物进行热解。该电催化剂（通过在氧化石墨烯层上接枝PdP纳米球获得）在电化学析氢反应（HER）中表现出高活性，驱动10 mA cm⁻²的阴极电流密度时过电位为133 mV。GO-PdP纳米复合材料坚固且有效，可连续进行HER长达16小时。
