Laser induced trace doping of Pd on Ru nanoparticles for an efficient hydrogen evolution electrocatalyst

Abstract

Improving the activity and stability of electrocatalysts for hydrogen evolution reaction (HER) plays an essential role in the practical application of electrochemical water splitting in alkaline conditions. Here, trace Pd-doped...

Ultralow-content Pt nanodots/Ni3Fe nanoparticles: interlayer nanoconfinement synthesis and overall water splitting

“…[3][4][5] The slow kinetics and high overpotentials of the oxygen and hydrogen evolution reactions (OER and HER) necessitate the utilization of cutting-edge electrocatalysts such as RuO 2 (or IrO 2 ) and Pt/C. 6 Their resource scarcity and high cost, however, slow down the advance toward further large-scale practical applications. 7 Therefore, it is crucial to construct cost-effective catalysts for electrocatalytic water splitting.…”

Laser Irradiation Synthesis of AuPd Alloy with Decreased Alloying Degree for Efficient Ethanol Oxidation Reaction

“…Consequently, modulating the alloying degree to alter the prevalence of continuous Pd sites Materials 2024, 17, 1876 2 of 13 can affect the electrocatalytic efficacy. The laser liquid-phase synthesis of nanomaterials has garnered considerable interest due to its low thermal budget [24], high efficiency, and environmental friendliness [25]. Pulsed laser irradiation in liquids (PLIL), characterized by its pronounced non-equilibrium and quenching effects [26], can rapidly elevate the temperature of nanoparticles to very high temperatures (thousands of kelvins) [27] within an exceedingly brief duration and subsequently cool them back to ambient temperature with a cooling rate ranging from 10 6 to 10 12 K/s [28].…”
