Boundary Investigation of High-Temperature Co-Electrolysis Towards Direct CO₂ Electrolysis

Spatially confined catalysis-enhanced high-temperature carbon dioxide electrolysis.

In this study, a potential ilmenite cathode material Ni0.9TiO3 is designed for efficient CO2 electrolysis in an oxide-ion-conducting solid-oxide electrolyzer. Spatially confined catalysis has been successfully achieved to substantially improve cathode activity by in situ growth of catalytically active nickel nanoparticles on a ceramic skeleton. The combined analysis of XRD, SEM, EDS, XPS, TGA a...

Urea electrolysis: direct hydrogen production from urinew

The utilization of wastewater for useful fuel has been gathering recent attention due to society’s need for alternative energy sources. The electrooxidation of urea found at high concentrations in wastewater simultaneously accomplishes fuel production and remediation of harmful nitrogen compounds that currently make their way into the atmosphere and groundwater. Pure hydrogen was collected in t...

Electrolysis-based diaphragm actuators.

This work presents a new electrolysis-based microelectromechanical systems (MEMS) diaphragm actuator. Electrolysis is a technique for converting electrical energy to pneumatic energy. Theoretically electrolysis can achieve a strain of 136 000% and is capable of generating a pressure above 200 MPa. Electrolysis actuators require modest electrical power and produce minimal heat. Due to the large ...

Hydrogen Production via CH4 and CO Assisted Steam Electrolysis

Porous composite anodes consisting of a yttria-stabilized zirconia (YSZ) backbone that was impregnated with CeO2 and various amounts of metallic components including Cu, Co and Pd were fabricated. The performance of these anodes was then tested in a solid oxide water electrolysis cell under conditions where the anode was exposed to the reducing gasses H2, CH4 and CO. The reducing gasses were us...
