天津,2023年9月26日 – 在可再生能源技术领域,开发低成本、高效的高通量筛选催化剂显得尤为重要。近日,天津大学巩金龙教授、赵志坚教授、张鹏教授领衔的研究团队,成功开发了一种通用且可解释的描述符模型ARSC,为电催化反应的活性和选择性预测提供了强有力的工具。

可解释机器学习的挑战与创新

可解释的机器学习通过提取物理意义来加速催化剂设计,然而,这一领域面临着诸多挑战。传统的催化剂设计往往依赖于繁琐的实验和理论计算,耗时且成本高昂。而ARSC模型的问世,无疑为这一领域带来了革命性的变化。

ARSC模型:突破传统界限

ARSC模型通过分析双原子位点的原子属性(A)、反应物(R)、协同(S)和配位效应(C),成功地将这些复杂因素解耦。这一创新性方法不仅简化了催化剂设计过程,而且大大提高了筛选效率。

实验验证与未来展望

在ARSC模型的驱动下,研究人员能够快速找到最佳催化剂,而无需进行50,000多次密度泛函理论计算。这一模型已通过大量已报道的研究和后续实验得到验证。其中,Co-Co/Ir-Qv3被确认为最佳的双功能氧还原和析氧电催化剂。

该研究成果以“Machine learning-assisted dual-atom sites design with interpretable descriptors unifying electrocatalytic reactions”为题,于9月17日发表在《Nature Communications》上,为高维系统的智能催化剂设计开辟了新道路。

结论

天津大学团队开发的ARSC模型,不仅为电催化反应的活性和选择性预测提供了新的视角,也为可再生能源技术的发展提供了有力支持。随着这一模型的不断完善和推广,我们有理由相信,它将在未来新能源领域发挥越来越重要的作用。
