Description

Hybrid Water Electrolysis presents a systematic account of how replacing the sluggish oxygen evolution reaction (OER) with the oxidation of small organic and inorganic molecules — alcohols, urea, hydrazine, furfural, formic acid and glucose — can lower the energy input of water electrolysis while generating value-added chemicals alongside green hydrogen. Bringing together an international editorial team from South Korea, India, Brazil and Thailand, the volume covers electrocatalyst design across metal sulfides, carbides, nitrides, phosphides, borides, selenides, alloys and single-atom catalysts, together with synthesis routes, reaction mechanisms, stability analysis and the scale-up challenges standing between laboratory results and commercial deployment.

Key Features

Covers the full electrocatalyst landscape for hybrid water electrolysis, from metal sulfides and carbides to single-atom catalysts. Explains advanced fabrication routes, including pulsed laser synthesis, alongside reaction-mechanism and stability analysis. Includes a dedicated chapter on commercialization pathways and the scale-up challenges facing energy-saving hybrid electrolysis systems.

Coverage

18 chapters organized in five parts: Fundamentals and Advantages of Hybrid Water Electrolysis; Alcohol-Assisted oxidation (carbides/nitrides, single atoms, alloys, borides/selenides, glycerol oxidation); Hydrazine-Assisted oxidation (sulfides, phosphides, carbides/nitrides, alloys, borides/selenides, single atoms); Urea and Furfural-Assisted oxidation (sulfides/phosphides, carbides/nitrides, single atoms, glucose oxidation); and Future Prospects, closing with a chapter on commercialization of energy-saving hybrid water electrolysis and a full index.

Three concrete applications of this volume's content: (1) designing lower-voltage electrolyzer stacks that pair green hydrogen production with value-added chemical co-generation; (2) benchmarking non-noble-metal electrocatalysts for pilot-scale hybrid electrolysis units; (3) supporting techno-economic assessment of hybrid electrolysis investment for industrial hydrogen and chemical production.

Q&A

Q: What is hybrid water electrolysis and how does it differ from conventional water splitting?
A: Hybrid water electrolysis replaces the energy-intensive oxygen evolution reaction at the anode with oxidation of a small organic or inorganic molecule — such as an alcohol, urea or hydrazine — which requires a lower voltage and produces a valuable co-product in addition to hydrogen at the cathode.

Q: Which electrocatalysts are most effective for small molecule oxidation in hybrid electrolysis?
A: The book reviews metal sulfides, carbides, nitrides, phosphides, borides, selenides, alloys and single-atom catalysts, comparing their activity and stability across different oxidation targets.

Q: How does replacing oxygen evolution with alcohol or urea oxidation reduce the energy cost of hydrogen production?
A: These molecules oxidize at a lower thermodynamic potential than water, so the overall cell voltage needed to drive hydrogen evolution at the cathode drops, cutting electricity consumption per unit of hydrogen produced.

Q: What are the main scale-up challenges for commercializing hybrid water electrolysis?
A: Chapter 18 addresses catalyst durability under continuous operation, feedstock supply and purity for the oxidized molecule, and the economics of co-product recovery at industrial scale.

Q: Where can I buy Hybrid Water Electrolysis: Non-Oxide Electrocatalysts in Small Molecule Oxidation?
A: It is available directly from CLNZ Books — Bookseller for Professionals Worldwide — with worldwide shipping included.
