The synthesis of PdP nanoparticles (NPs) using triphenylphosphine as a phosphorus precursor was investigated. The electrocatalytic performance of PdP NPs in hydrogen evolution reaction in an alkaline medium was measured. It can be concluded that when the current density is 10[Formula: see text]mA[Formula: see text]cm[Formula: see text], the overpotential produced by Pd3P[Formula: see text] NPs is 75[Formula: see text]mV which is 185[Formula: see text]mV lower than that produced by commercial Pd/C. The mass activity of Pd3P[Formula: see text] NPs is more than twice as high as that of commercial Pd/C. The work indicates that PdP nanomaterials could be a potential catalyst for water splitting.

Pt-MoS2 composites are fabricated via growing tunable Pt nanoparticles size (NPs, 2–6 nm) on single-layer MoS2 nanosheets. Which have shown excellent performance for hydrogen evolution reaction (HER) with the Pt NPs exhibiting a volcano-type size effect toward mass activity due to the synergistic effects between the Pt NPs and MoS2.

Complex Salts

Cobaloximes and their BF<sub>2</sub>-bridged analogues have emerged as promising non-noble metal catalysts for the photocatalytic hydrogen evolution reaction (HER). Herein we report the serendipitous discovery that double complex salts such as [Co(dmgh)<sub>2</sub>py<sub>2</sub>]<sup>+</sup>[Co(dmgBPh<sub>2</sub>)<sub>2</sub>Cl<sub>2</sub>]<sup>-</sup> can be obtained in good yields by treatment of commercially available [Co(dmgh)<sub>2</sub>pyCl] with triarylboranes. A systematic study on the use of such double complex salts and their single salts with simple counterions as photocatalysts revealed HER activities comparable or superior to existing cobaloxime catalysts and suggests ample opportunities for this compound class in catalyst/photosensitizer dyads and immobilized architectures. Preliminary electrochemical and spectroscopic studies indicate that one key advantage of these charged cobalt complexes is that the reduction potentials as well as the electrostatic interaction with charged photosensitizers can be tuned.
