A Janus heteroatom-doped carbon electrocatalyst for hydrazine oxidation

Jieting Ding et al.

Summary: We report a Janus-type carbon material combining electrically conductive nitrogen-doped carbon (NC) and catalytically active boron, nitrogen co-doped carbon (BNC), which can resolve the trade-off between intrinsic activity and electronic conductivity. The Janus carbon electrocatalyst exhibits superior activity in the electrocatalytic hydrazine oxidation reaction (HzOR) compared to single counterparts and physical mixtures. The NC/BNC interfaces promote efficient electron transport and decrease the free energy of the rate-determining step in the HzOR process.

Main-Group Metal Single-Atomic Regulators in Dual-Metal Catalysts for Enhanced Electrochemical CO2 Reduction

Chenghong Hu et al.

Summary: In this study, the authors demonstrate that introducing HER-inert main-group metal single atoms adjacent to transition-metal single atoms can enhance the CO2RR to CO without inducing the HER side reaction. The dual-metal Cu and In single-site atoms prepared by pyrolysis show superior catalytic performance compared to their monometallic counterparts.

Integrated Reference Electrodes in Anion-Exchange-Membrane Electrolyzers: Impact of Stainless-Steel Gas-Diffusion Layers and Internal Mechanical Pressure

Qiucheng Xu et al.

Summary: This study introduces a new method to separate the responses of the anode and cathode in polarization and impedance measurements by integrating a reference electrode with the MEA, revealing how changes in the fiber diameter of stainless-steel gas-diffusion layers (GDLs) and the thickness of the cathode GDL simultaneously affect the performance of the anode and cathode in alkaline-membrane electrolyzers. This approach guides the development of high-performance alkaline-membrane water electrolyzers and demonstrates a useful strategy for studying structure-activity relationships in the MEA.

Dendritic gold-supported iridium/iridium oxide ultra-low loading electrodes for high-performance proton exchange membrane water electrolyzer

Hyunki Kim et al.

Summary: The innovative electrode design with ultra-low Ir loading proposed in this study achieves high catalytic OER performance, catalyst utilization, and activity-stability balance by controlling the Ir deposition pulses and coverage to affect the Ir electronic structure. Adjustments to the Ir electronic structure through the formation of Ir oxides further enhance the cell performance, demonstrating significantly high mass activity exceeding state-of-the-art Ir-based anodes.

A review of the porous transport layer in polymer electrolyte membrane water electrolysis

Tuan Linh Doan et al.

Summary: Polymer electrolyte membrane water electrolysis (PEMWE) is a promising and environmentally friendly method for hydrogen production, but only contributes 4% of global hydrogen production due to economic challenges. Recent research on porous transport layers (PTL) aims to reduce costs and enhance performance of PEM water electrolysis.

Oxygen Evolution Reaction Activity and Stability Benchmarks for Supported and Unsupported IrOx Electrocatalysts

Camila Daiane Ferreira da Silva et al.

Summary: Supported IrOx nanocatalysts are more active but less stable for OER compared to unsupported micrometer-sized catalysts, while Ta-doped tin oxides used as supports for IrOx nanoparticles show higher stability. Thermal annealing significantly reduces Ir atom dissolution rate for both micro- and nano-IrOx particles, leading to improved stability.
