Hybrid water electrolysis with integrated and cascading reactions using two-dimensional electrocatalysts

Abstract

Electrocatalytic water splitting has become a promising channel for green hydrogen production. However, the high energy barrier and sluggish kinetics of anodic oxygen evolution reaction (OER) burden the industrial application,...

Fundamentals, Applications, and Perspectives of Liquid Metals in Catalysis: An Overview of Molecular Simulations

“…87−89 It is of great interest to develop alternative energy-saving technologies for hydrogen production, such as using 2D electrocatalysts via hybrid water electrolysis or employing liquid metals via the Al−H 2 O reaction. 90,91 Gabased liquid metal alloys can remarkably enhance the reactivity of Al in the Al−H 2 O reaction by decreasing the Al reactant size, amplifying the reactive surface area, inhibiting the formation of aluminum oxides, and mitigating the surface energy. The highest rate of hydrogen evolution depends upon the composition of the liquid metal alloy.…”

“…Another study by Kawasaki et al demonstrated the conversion of ethanol to graphitic carbon at the interface of eutectic gallium indium under ultrasonic conditions . In addition, a group of Ga-based catalysts, including compositions, such as Ga, Ga–Sn/In/Zn, and Galinstan, have been developed to facilitate the reaction between aluminum (Al) and water, offering an alternative route for hydrogen production through water splitting. − It is of great interest to develop alternative energy-saving technologies for hydrogen production, such as using 2D electrocatalysts via hybrid water electrolysis or employing liquid metals via the Al–H 2 O reaction. , Ga-based liquid metal alloys can remarkably enhance the reactivity of Al in the Al–H 2 O reaction by decreasing the Al reactant size, amplifying the reactive surface area, inhibiting the formation of aluminum oxides, and mitigating the surface energy.

Electronic structure modification of ultrathin MnFeOOH and integration with Ni3S2 as bifunctional electrocatalysts for improved alkaline water splitting

“…After years of development, many transition metal electrocatalysts, such as transition metal oxides, hydroxides, sulfides, carbides, sulfides and MOFs, etc., have made significant progress. [6][7][8][9][10][11][12][13] However, these catalysts still generally have poor conductivity, and unsatisfactory catalytic activity and stability. 14 Additionally, most current electrocatalysts are single functional, while bifunctional water electrolysis catalysts are relatively rare.…”
