With the aid of density functional theory, an evaluation of a series of non-metallic elements B-, C-, N-, O-, S-, and Si-doped Hittorf's violet phosphorene (HP) as HER catalysts are reported. Our results demonstrate that the incorporation of these non-metallic dopants can effectively improve the HER performance for the HP, implying that the doping can indeed break the inertia of the HP basal plane and enhance the interaction between the H atom and active sites. The improved HER activities are ascribed to suitable hydrogen adsorption abilities which are well correlated with the <em>p</em><sub>z</sub>-band center and charge transfer of the dopant. According to calculated exchange current density <em>i</em><sub>0</sub> and pH-dependent H adsorption Δ<em>G</em><sub>H∗</sub>, in an acidic environment, seven doped systems own high <em>i</em><sub>0</sub> (&gt;0.1 mA/cm<sup>2</sup>) and the N/Si-codoping (configuration I, site N) has the best HER activity with 1.520 mA/cm<sup>2</sup>.
