Photochemically synthesized cobalt oxide hydroxide (PCOH) under UV light has been successfully achieved without the addition of surfactants, templates, or organic solvents at ambient temperatures. PCOH samples can be converted to spinel cobalt oxide (PCO) after the calcination at 500°C. The in-situ growth of hierarchical nanostructures was demonstrated with a three-stage mechanism in the photochemical...
Graphene hybrids comprised of diverse functional materials have shown exceptional performance. However, only 2D composites were widely studied, the understanding of graphene hybridization behavior with complex 3D nanostructures remains unclear. In this work, we investigate how the graphene hybridization is affected by the presence of 3D nanovoids, and the corresponding influence on the electrocatalysis...
