Abstract

Seawater electrolysis shows potential for sustainable hydrogen production but faces challenges from the high concentration of Cl, which leads to corrosion and performance degradation. In this study, we prepared a NiFe layered double hydroxide (NiFe LDH) nanoarray modified with poly(3-thiophenemalonic acid) (PTPA) on Ni foam (NiFe LDH@PTPA/NF) to enhance alkaline seawater oxidation (ASO). PTPA serves as a conductive and protective layer, improving electrical conductivity and repelling Cl to increase stability. The electrode demonstrated stable operation at 1000 mA cm2 with low overpotential for 600 h, generating minimal chlorine. In situ Raman spectroscopy confirmed that PTPA facilitates active site formation and provides Cl protection, while inductively coupled plasma-optical emission spectrometry analysis indicated reduced Ni and Fe leaching. This study highlights the potential of conductive polymers to enhance ASO performance and durability.

期刊介绍: ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times. The editors and staff of ACS Materials Letters actively participate in major scientific conferences and engage closely with readers and authors. The journal also maintains an active presence on social media to provide authors with greater visibility.
