Catalytic phase change dielectric sphere for methanol combustion and preparation method therefor

The present invention discloses a catalytic phase change dielectric sphere for methanol combustion and a preparation method therefor. The catalytic phase change dielectric sphere for methanol combustion is mainly prepared from a high-temperature phase change material, an active material, a carrier material, a catalyst, a nano-semiconductor material, a nano-transition metal and an adhesive. A catalytic phase change dielectric solid sphere is prepared with a mixed pressing and sintering process, the methanol energy conversion rate reaches 87.5%, the furnace temperature of methanol combustion reaches 900° C. or higher, and waste heat recovery is realized; or, a catalytic phase change dielectric microporous hollow sphere is prepared through electrostatic adsorption and in-site redox reaction, the methanol energy conversion rate reaches 99% or higher, the furnace temperature of methanol combustion reaches 1000° C. or higher, and waste heat recovery is realized.
