Designing electrocatalysts for seawater splitting: surface/interface engineering toward enhanced electrocatalytic performance

Abstract

As an ideal large-scale energy conversion/storage technology, electrochemical hydrogen production is a great potential means of smoothing out the volatility of renewable sources. Electrocatalytic seawater splitting utilizes abundant natural seawater...

Non-noble metal catalysts for preventing chlorine evolution reaction in electrolytic seawater splitting

“…Hence, the fabrication of catalysts that can selectively produce oxygen in direct electrolytic seawater splitting is one of the key problems to be solved. 40 Most of the previously reported efficient catalysts for the electrolysis of seawater anodes are mainly iridium oxide and highly selective nickel-based metal materials. [41][42][43][44] Although IrO x has good stability at high current densities, Ir metal is relatively expensive to use in seawater electrolysis, and thus not suitable for large-scale production.…”

A review of water splitting via mixed ionic–electronic conducting (MIEC) membrane reactors

“…Water is the most ideal natural source of hydrogen, and electrical water splitting (or water electrolysis) and water photolysis have become attractive technologies due to the potential to use clean renewable energy. 6,7 Photocatalytic water splitting uses two of the most abundant and cleanest resources, thus displaying superior economic and environmental benefits. Research on photocatalytic water splitting is developing rapidly, especially the exploration of photoelectrode materials and photocatalytic materials.…”

Functions of metal–phenolic networks and polyphenol derivatives in photo(electro)catalysis

“…10,11 In particular, advanced surface and interface engineering has been critical to the development of efficient and stable photoanodes for water oxidation. 12 As a bridge linking different components of composite materials, the interface has a significant influence on charge transport and catalytic properties. Surface engineering technology is commonly used to modify semiconductor-electrolyte interfaces in order to improve the PEC performance.…”
