Magnesium ferrites (MgFe₂O₄) are important class of ferrites that have been receiving greater attention as promising excellent photocatalyst due to its low cost, wide light spectrum response and environment-friendly nature. However, its poor electronic conductivity and fast charge carrier recombination hinders its electrocatalytical applications. Hence, accelerating charge carriers separation efficiency is important to modify the photoelectrochemical performance of MgFe₂O₄. Herein, novel Zn ions doped MgFe₂O₄ nanospheres are fabricated for the first time. Zn ions are doped into MgFe₂O₄ nanostructures from surface to enhance their charge separation efficiency. The doped MgFe₂O₄ nanostructures show significant photocatalytic activity and enhanced photocurrent density than that of pristine MgFe₂O₄.The improved photoelectrocatalytic performance is attributed to doping effect, were Zn ions actually enhance the conductivity. Zn ions enhance the activity of MgFe₂O₄ and accelerate the charge transfer properties in MgFe₂O₄. The results highlight that Zn doped MgFe₂O₄ nanospheres could be a potential candidate for photocatalytic and photoelectrochemical applications.

镁铁氧体（MgFe ₂ O ₄）是一类重要的铁氧体，由于其低成本、宽光谱响应和环境友好的性质，作为有前途的优良光催化剂而受到越来越多的关注。然而，其较差的电子导电性和快速的电荷载流子复合阻碍了其电催化应用。因此，提高电荷载流子分离效率对于改变MgFe ₂ O ₄的光电化学性能很重要。在此，首次制备了新型Zn离子掺杂的MgFe ₂ O ₄纳米球。Zn离子掺杂到MgFe ₂ O _{4 中}纳米结构以提高其电荷分离效率。掺杂的MgFe ₂ O ₄纳米结构显示出比原始MgFe ₂ O ₄显着的光催化活性和增强的光电流密度。改进的光电催化性能归因于掺杂效应，而Zn离子实际上增强了电导率。Zn离子增强MgFe的活性₂ Ó ₄和MgFe加速的电荷转移性质₂ Ò ₄。结果突出表明，Zn 掺杂的 MgFe ₂ O ₄纳米球可能是光催化和光电化学应用的潜在候选者。
