It is vitally essential to propose a novel, economical, and safe preparation method to design highly efficient electrocatalysts. Herein, phosphorus‐doped iron nitride nanoparticles encapsulated by nitrogen‐doped carbon nanosheets are grown directly on the iron foam substrate (P‐Fe₃N@NC NSs/IF) by in situ deriving from Saccharomycetes cerevisiae (S. cerevisiae), where anion elements of C, N, and P all from S. cerevisiae replace the hazardous CH₄, NH₃, and H₃P. The diffusion pattern of N, P in S. cerevisiae and contact form between metal and S. cerevisiae observably affect the composition and phase of the product during high‐temperature calcination. The obtained P‐Fe₃N@NC NSs/IF demonstrates superior electrocatalytic performance for the hydrogen evolution reaction and oxygen evolution reaction, also satisfying durability. Theoretical calculation confirms that Fe sites of P‐Fe₃N serve as the active center, and N sites and P doping regulate the hydrogen binding strength to enhance catalytic ability. Additionally, the two‐electrode electrolyzer assembled by P‐Fe₃N@NC NSs/IF as both anode and cathode electrodes needs only 1.61 V to reach 10 mA cm⁻² for overall water splitting with a superb stability. The S. cerevisiae‐based process presents a feasible approach for synthesis of nitrides, carbides, phosphides, and electrocatalytic applications.

氮杂碳纳米片在啤酒酵母铁泡沫上原位包裹的氮掺杂碳纳米片包裹的磷掺杂氮化铁纳米粒子，用于电催化总水分解。

提出一种新颖，经济，安全的制备方法来设计高效电催化剂至关重要。在此，通过氮杂碳纳米片封装的磷杂化的氮化铁纳米颗粒直接通过源自酿酒酵母（S. cerevisiae）的原位衍生而在铁泡沫基质（P-Fe ₃ N @ NC NSs / IF）上生长。所有从C，N，和P的元素酿酒酵母更换危险CH ₄，NH ₃和H ₃ P. N的扩散图案，P中的酿酒酵母和金属之间的接触形式酿酒酵母在高温煅烧过程中，明显影响产品的组成和相。所获得的P-Fe ₃ N @ NC NSs / IF表现出优异的电催化性能，可用于氢气释放反应和氧气释放反应，同时还满足耐久性要求。理论计算证实，P-Fe ₃ N的Fe位为活性中心，N位和P掺杂调节氢结合强度以增强催化能力。此外，由P-Fe ₃ N @ NC NSs / IF组装成阳极和阴极的两电极电解槽仅需1.61 V即可达到10 mA cm ^-2的总水分解性能，并具有出色的稳定性。在酿酒酵母基于过程的过程为合成氮化物，碳化物，磷化物和电催化应用提供了一种可行的方法。
