Hierarchical porous NiFe-P@NC as an efficient electrocatalyst for alkaline hydrogen production and seawater electrolysis at high current density

Abstract

Economical, efficient and stable transition-metal electrocatalysts are considered as great candidatures for replacing noble-metal materials for alkaline hydrogen production. Hence, corrosion engineering and mild phosphating processes is adopted to construct...

Ultrafast Microwave Synthesis of Ru-Doped MoP with Abundant P Vacancies as the Electrocatalyst for Hydrogen Generation in a Wide pH Range

“…With increasing demand for energy and the growing concern over environmental pollution, it is pressing to exploit alternative energies to substitute non-renewable fossil fuels. − As a sustainable clean energy source, hydrogen is considered an ideal candidate for sustainable energy supply. − Among the developed hydrogen production technologies, electrocatalytic water electrolysis is an eco-friendly and efficient way for hydrogen generation. − To optimize the reaction efficiency, designing highly efficient and stable catalysts for the hydrogen evolution reaction (HER) is important. At present, platinum (Pt) and its derivatives are recognized as benchmarked HER catalysts, but their high cost and shortage limit their large-scale commercial applications. ,− Therefore, the development of inexpensive and efficient catalysts for HER is critical for achieving hydrogen production through water electrolysis.…”

Achieving favourable oxygen electrocatalytic activity with compositionally complex metal molybdates

“…Precious noble metals, such as Pt and Ru/Ir, are considered state-of-the-art high-performing electrocatalysts in HER/ORR and OER, respectively. [9][10][11] However, their high cost and limited resource hinder their large-scale applications. 10 Although several efforts have been made to reduce the precise noble metal content and incorporate them with transition metals or metal oxides with engineered architectures and electronic congurations to boost the catalytic activity, nullifying them is highly desirable to reduce the cost for widescale applications.…”

Orange-peel derived carbon-loaded low content ruthenium nanoparticles as ultra-high performance alkaline water HER electrocatalysts

“…[11][12][13] In recent years, people have done a lot of work on non-noble metal catalysts, and many new and efficient electrocatalysts have also been successfully developed, such as transition metal oxides, transition metal sulfides, transition metal carbides, and carbon-doped materials. [14][15][16][17][18] The discovery and research of carbon materials have opened up new ways and new directions to replace noble metal catalysts. 19,20 For example, graphene has attracted extensive attention due to its large specific surface area, high conductivity, good chemical stability, and structure and surface modifiability.…”
