Integrating trace amounts of Pd nanoparticles into Mo₃N₂ nanobelts for an improved hydrogen evolution reaction

Abstract

Significant efforts have been directed towards the use of transition metal nitrides as electrocatalysts for hydrogen evolution reaction (HER). Molybdenum nitride, despite its promise for scalable production, suffers from the...

Lithiophilic Interphase Porous Buffer Layer toward Uniform Nucleation in Lithium Metal Anodes

“…[42] Mo 3 N 2 has metallic characteristics, which is reported in literatures. [43,44] The difference in the work function suggests that there would be band alignments and self-driven electron transfer from Mo 3 N 2 to MoO 2 at their coupling heterointerfaces during contact until the work function equilibrium is reached. As the corresponding schematic energy band diagrams illustrated in Figure 5e, a spontaneous BIEF pointing toward the MoO 2 side can be formed when the metallic Mo 3 N 2 and semiconducting MoO 2 are in contact.…”

Pt- and Pd-modified transition metal nitride catalysts for the hydrogen evolution reaction

“…Transition metal carbides (TMCs), transition metal phosphides (TMPs), transition metal borides (TMBs), and transition metal nitrides (TMNs) have been explored as electrocatalysts for the HER. 38–62 Abghoui et al 54 reported that TaN, HfN, MoN, and ScN catalyze the HER at overpotentials between −0.09 V and −0.34 V. Peterson et al 63 demonstrated that the activity of TMC catalysts is between low activities shown by early transition metals and high activities shown by compounds of Pt/Pt-group metals. In addition to the above, TMPs have also been explored as potential catalysts for the HER, including the phosphides of Co, Ni, and Fe.…”

Si regulation of hydrogen adsorption on nanoporous PdSi hybrids towards enhancing electrochemical hydrogen evolution activity

“…The other method is to obtain a moderate binding strength for Pd through the strong interaction between the catalyst and support by means of the functional support (synergistic and ligand effects), so as to improve its hydrogen precipitation activity. These supports include CoS 2 , 26 MoS 2 , 27,28 VS 2 , 29 NiCo 2 S 4 , 30 Mo 3 N 2 , 31 MoO 3 , 32 TiO 2 , 33 FeOx (OH) 2 , 6 Co/CoO x , 34 graphene, 14,21,35,36 and graphitized carbon nanofibers. 37 Last, the most important way is to synthesize Pdbased alloys, and to change the hydrogen adsorption energy on their surfaces through the electronic effect between the alloys, which is the key parameter for HER.…”
