摘要
电催化裂解水制氢工艺具有绿色环保、简洁高效、氢气组分纯度高等优势,是最具应用价值的绿氢制造方式之一。但是,由于阴极和阳极电极反应动力学较为缓慢导致当前能源转换效率较低。利用高效、稳定的电催化裂解水制氢催化剂加速反应动力学过程,降低析氢反应电势,是大规模高效电催化裂解水制氢的关键所在。与传统的粉末状催化材料相比较,自支撑材料不仅不需要使用粘结剂,还具有极高的比表面积、较高的稳定性、高效的电荷传输速率及产物生成速率等优势,还可以按需构筑多种维度的新型电极结构,如一维、二维和三维等。基于此,主要介绍了自支撑过渡金属基电极材料的结构设计和可控合成方面的最新进展。
With green environmental,simple process and high purity of hydrogen,Hydrogen production by electrolytic water splitting technology is a promising way to produce hydrogen continuously in the future.However,the electrode reaction has a high thermodynamic energy barrier,which leads to low energy conversion efficiency.Therefore,the development of efficient and stable electrolytic water catalysts is the key to accelerate the slow reaction kinetics and reduce the reaction overpotential,so as to achieve large-scale for hydrogen production by electrolytic water splitting.Compared with traditional powder catalytic materials,self-supporting materials not only do not require the use of binders,but also have the advantages of extremely high specific surface area,high stability,efficient charge transfer rate and product generation rate,and can also be constructed according to the needs of a variety of new electrode structures,such as one-dimensional,two-dimensional and three-dimensional.Therefore,this paper mainly introduces the latest progress in the structural design and controllable synthesis of self-supporting transition metal-based electrode materials.
