Abstract

In-Situ Resource Utilization (ISRU) is essential for sustainable exploration of the moon. The surficial lunar basalts (LB) are the most likely primary feedstock in ISRU processes. In this work, we have developed an in-situ synthesis technology, laser scanning ablation, to synthesize LB-supported electrocatalysts for hydrogen evolution reaction (HER). The laser-induced high-entropy spherical LB becomes convenient supports for hosting well-dispersed Pt species. Owing to the atomic rearrangement caused by the high-energy laser irradiation, strong physicochemical interactions between Pt species and LB are confirmed with the formation of Pt-O and Pt-Fe bonds. The tight cohesion endows Pt/LB faster charge-transfer rate and higher turnover frequency during HER. In both alkaline and acidic media, the Pt/LB catalyst possesses a near-zero onset overpotential and a low Tafel slope, superior to most Pt catalysts loaded on other supports. It is theoretically verified that Pt-Fe or Pt-O coordination can result in a smaller reaction barrier and a shorter diffusion time than pure Pt, thereby improving the catalytic activity of HER. The LSA method provides a simple and robust path to process LB in-situ as an excellent catalyst carrier while enabling the deposition of various metals on its surface for extended application in ISRU.

原地资源利用(ISRU)对于月球的可持续探索至关重要。月球表面玄武岩(LB)最有可能成为 ISRU 过程中的主要原料。在这项工作中,我们开发了一种原位合成技术--激光扫描烧蚀,用于合成以月球玄武岩为支撑的氢进化反应(HER)电催化剂。激光诱导的高熵球形枸橼酸枸橼酸枸橼酸枸橼酸(LB)成为了承载良好分散的铂物种的便捷支撑。由于高能激光辐照引起的原子重排,铂元素与枸杞之间产生了强烈的物理化学相互作用,形成了铂-O 和铂-铁键。这种紧密的内聚力使铂/枸杞在 HER 过程中具有更快的电荷转移速率和更高的周转频率。在碱性和酸性介质中,Pt/LB 催化剂都具有接近零的起始过电位和较低的塔菲尔斜率,优于负载在其他载体上的大多数铂催化剂。理论证明,与纯铂相比,铂-铁或铂-氧配位可导致更小的反应势垒和更短的扩散时间,从而提高 HER 的催化活性。LSA 方法为原位处理枸杞提供了一条简单而稳健的途径,可将枸杞作为一种优良的催化剂载体,同时还能在其表面沉积各种金属,以扩展其在 ISRU 中的应用。
