The electronic properties and OER catalytic activity of pristine BeN4 monolayers and single-transition-metal-doped BeN4 monolayers (TM@BeN4) were systematically investigated using density functional theory. Among all the types of TM@BeN4 analyzed, Fe@BeN4 was determined to exhibit the best OER activity, with an overpotential of 0.33 V, and to display excellent metallic conductivity. Besides, the OER catalytic activity of Fe@BeN4 can be further enhanced by applying biaxial strain and designing X-Fe@BeN4 (X = B, C, O, P, S) catalysts.

过渡金属掺杂 BeN4 单层的可调电子结构和优异的催化性能



使用密度泛函理论系统研究了原始 BeN4 单层和单过渡金属掺杂 BeN4 单层 (TM@BeN4) 的电子性质和 OER 催化活性。在分析的所有类型的 TM@BeN4 中,Fe@BeN4 被确定表现出最佳的 OER 活性,过电位为 0.33 V,并显示出优异的金属导电性。此外,通过施加双轴应变和设计 X-Fe@BeN4 (X = B、C、O、P、S) 催化剂,可以进一步提高 Fe@BeN4 的 OER 催化活性。
