Room-temperature fabrication of defective CoOxHy nanosheets with abundant oxygen vacancies and high porosity as efficient 5-hydroxymethylfurfural oxidation electrocatalysts

Defective cobalt oxide hydrate nanosheets with abundant oxygen vacancies and high porosity were fabricated via room-temperature reductive treatments, and they performed well in the electrocatalytic oxidation reaction of 5-hydroxymethylfurfural.
