“…Until now, various methods have been developed for improving HER performance, including alloy [37][38][39], doping [40,41], selenization [42,43], carbonization [44][45][46][47][48], nitridation [49][50][51][52], etc. The design of cathode electrocatalysts has been introduced in many other reviews [53][54][55]; herein, we only provide some representative work.…”

The utilization of renewable energy for hydrogen production presents a promising pathway towards achieving carbon neutrality in energy consumption. Water electrolysis, utilizing pure water, has proven to be a robust technology for clean hydrogen production. Recently, seawater electrolysis has emerged as an attractive alternative due to the limitations of deep-sea regions imposed by the transmission capacity of long-distance undersea cables. However, seawater electrolysis faces several challenges, including the slow kinetics of the oxygen evolution reaction (OER), the competing chlorine evolution reaction (CER) processes, electrode degradation caused by chloride ions, and the formation of precipitates on the cathode. The electrode and catalyst materials are corroded by the Cl− under long-term operations. Numerous efforts have been made to address these issues arising from impurities in the seawater. This review focuses on recent progress in developing high-performance electrodes and electrolyser designs for efficient seawater electrolysis. Its aim is to provide a systematic and insightful introduction and discussion on seawater electrolysers and electrodes with the hope of promoting the utilization of offshore renewable energy sources through seawater electrolysis.

The ability to control the compositional phase in first row transition metal bimetallic carbides as well as systematically controlling the metal ratio is complicated by the rich phase diagram, differences in metal reactivity, and differences in carbon solubility in the first-row metal carbides. Prussian blue analogues (PBAs) have been shown to act as a single source precursor for the formation of nanocrystal metal carbides with maintenance of their metal. An investigation of crystal phase control in the ternary (Fe x Co1–x ) y C z formed by PBA collapse is yet to be explored. In this study, we demonstrate the ability to tune phase (from most carbon rich to least carbon rich) M2C, M5C2, M7C3, and M3C, as well as the bimetallic alloy (M) in bimetallic FeCo nanocarbides through a strategy that pairs synthetic and density functional theory approaches to enable future targeted structure–function research on intriguing catalytic, therapeutic, and magnetic applications.
