Non-oxide electrocatalysts for energy-saving hybrid water electrolysis systems

Replacing thermodynamically unfavorable oxygen evolution with small molecule oxidation can reduce the energy input of water electrolysis while co-producing value-added chemicals. Hybrid Water Electrolysis: Non-Oxide Electrocatalysts in Small Molecule Oxidation, written by a team of electrochemistry and catalysis researchers from four countries, provides detailed coverage of functional electrocatalysts -- metal sulfides, carbides, nitrides, phosphides, and single atom catalysts --applied to this coupled approach.

The book examines nanostructured electrocatalytic materials developed via pulsed laser techniques and their deployment in hybrid electrolyzers for hydrogen fuel production alongside oxidation of benzyl alcohol, methanol, ethanol, urea, hydrazine, furfural, and formic acid. Coverage includes reaction mechanisms, governing principles for catalytic behavior, stability analysis, and an assessment of challenges and opportunities for scaling these systems to industrial application.

Readers will also find:

• Detailed discussion of metal sulfide, carbide, nitride, and phosphide electrocatalysts and their catalytic mechanisms in small molecule oxidation reactions
• Case studies illustrating how hybrid electrolyzer configurations simultaneously produce hydrogen fuel and value-added chemical products at reduced energy cost
• Analysis of single atom catalysts and their role in enhancing selectivity and activity for coupled electrolysis processes
• Coverage of pulsed laser synthesis techniques for fabricating nanostructured electrocatalytic materials with controlled morphology and composition
• Assessment of scale-up challenges and industrial opportunities for transitioning hybrid water electrolysis from laboratory to commercial deployment

Designed for catalytic chemists, surface chemists, physical chemists, inorganic chemists, and chemical engineers, this reference delivers the mechanistic detail and materials science coverage required to advance non-oxide electrocatalyst development for hybrid water electrolysis and sustainable hydrogen production.
