▎ 摘　　要

NOVELTY - Preparing platinum atom-loaded nano-titanium(II) oxide dense foam comprises (i) dissolving polyvinylpyrrolidone and chloroplatinic acid in ethylene glycol, performing ultrasonic treatment, heating to obtain platinum atomic suspension, (ii) obtaining titanium dioxide nanofibers by electrospinning technology, immersing titanium dioxide nanofibers in the platinum atomic suspension diluted with ethanol, stirring, washing and drying at room temperature to obtain platinum atom-deposited titanium dioxide nanofibers, (iii) using graphene oxide as a raw material through hydrothermal reduction to obtain reduced graphene oxide reduced graphene oxide (RGO) hydrosol, (iv) using the reduced graphene oxide RGO hydrosol as the cross-linking agent, uniformly mixing the platinum atom-deposited titanium dioxide nanofibers and the cross-linking agent and then freeze-drying to obtain platinum atom-supported nano-titanium dioxide dense foam. USE - The method is useful for preparing platinum atom-loaded nano-titanium(II) oxide dense foam. ADVANTAGE - The method: is simple, and easy to control; has low requirements on equipment; is suitable for large-scale production; has regular morphology and uniform particle size, high specific surface area, and stable three-dimensional layered structure; provides more contact interface; and improves the catalytic ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for platinum atom-loaded nano-titanium(II) oxide dense foam prepared by above mentioned method.
