Two-dimensional (2D) layered molybdenum disulfide (MoS2) materials have attracted a wide range of attention due to their unique physical and chemical properties as well as their tunable electronic structures. Nowadays, hydrogen evolution reaction (HER) in water splitting is crucial to the cost-effective production of the pure hydrogen fuel, while oxygen reduction reaction (ORR) in fuel cells has been suffering from sluggish reaction kinetics even if a high loading of platinum is applied. In this context, it is of great urgency to develop new catalysts comparable to traditional noble metal catalysts in electrocatalytic activity but composed of earth-abundant elements. In the past decade, 2D layered MoS2-based materials have demonstrated great potential as non-noble metal catalysts for both HER and ORR to meet the two aforementioned requirements. To this end, we conduct this survey aimed at summarizing the recent efforts in addressing electrocatalytic issues involved in HER and ORR activities using 2D MoS2 materials. Starting from an introduction on the superiorities of MoS2-based electrocatalysts for HER and ORR in this review, we then discuss the critical obstacles faced by MoS2 nanosheets with respect to their catalytic activities. Subsequently, we summarize the recent strategies for improving the catalytic activity of MoS2-based materials and the updated advances. In the end, we suggest potential pathways for high-catalytic performance comparable to those of their noble-metal counterparts and give some perspectives on practical applications of MoS2-based materials in the future. The insightful views from this review are believed to be greatly beneficial for accomplishing a better understanding on 2D layered MoS2-based material catalysts in electrocatalytic activities.

了解二维MoS 2纳米片及其复合材料的高电催化性能
二维（2D）层状二硫化钼（MoS 2）材料因其独特的物理和化学特性以及可调谐的电子结构而吸引了广泛的关注。如今，水分解中的析氢反应（HER）对于高成本效益的纯氢燃料生产至关重要，而燃料电池中的氧还原反应（ORR）一直反应迟钝，即使铂的负载量很高。应用。在这种情况下，迫切需要开发在电催化活性方面可与传统贵金属催化剂媲美但由富含地球的元素组成的新型催化剂。在过去的十年中，二维将MoS 2分层基材料已显示出作为非贵金属催化剂的巨大潜力，可满足HER和ORR满足上述两个要求。为此，我们进行此调查的目的是总结使用2D MoS 2材料解决涉及HER和ORR活动的电催化问题的最新努力。在本综述中，从介绍基于MoS 2的电催化剂对HER和ORR的优势开始，然后我们讨论MoS 2纳米片在其催化活性方面面临的关键障碍。随后，我们总结了提高MoS 2催化活性的最新策略资料和最新进展。最后，我们提出了与其贵金属同行相当的高催化性能的潜在途径，并就未来基于MoS 2的材料的实际应用提供了一些见解。据信，来自该综述的有见地的观点对于在电催化活性中完成对基于2D层状MoS 2的基于层的MoS 2的材料催化剂的更好理解是非常有益的。
