开发性能优良的非贵金属制氢催化剂仍是迫切需要的。基于MOP的催化剂被证明是很好的候选催化剂，并强烈鼓励进一步改进。因此，提出了一种新的N掺杂策略来提高MoP基催化剂的HER性能，其中选择了N(CH2COOH)3(NTA)作为N的掺杂元素，通过NTA的加入，成功地制备了分布均匀的N掺杂的MOP催化剂，表现出更小的颗粒尺寸、更小的电阻、更多的活性中心和更好的活性中心，从而使其性能比单纯的MOP更好。这一策略也可以推广到其他同行，通过N兴奋剂进一步提高她的运动能力。
It is still strongly required to explore non-noble catalysts with excellent performances for hydrogen generation. MoP-based catalysts are demonstrated as good candidates and further improvements are highly encouraged. Herein, a novel strategy of N-doping has been proposed to increase the HER performance over the MoP-based catalysts, in which nitrilotriacetic acid (N(CH2COOH)3, NTA) is selected to provide the doping element of N. With the addition of NTA, the N-doped MoP catalysts with good distribution have been successfully prepared, showing smaller particle size, reduced electrical resistance, increased amount and better quality of active sites, resulting in much better performances compared to pure MoP. This strategy can also be extended to other counterparts for the further improvement of HER activity by N-doping.
