Abstract: An Aluminum nitride ceramic and preparation method thereof. The aluminum nitride ceramic comprises a porous aluminum nitride matrix. A ferrite is loaded on the pore surface of the porous aluminum nitride matrix; and nano nickel particles are loaded on the surface of the ferrite. The preparation method of the aluminum nitride ceramic comprises steps: sintering the aluminum nitride ceramic by pressureless sintering method, depositing the ferrite on pore surface of porous aluminum nitride matrix by hydrothermal method, and loading nano nickel particles on the surface of the ferrite by reduction method. A micro-reactor is provided. So that the technical problems: the preheating time of the micro-reactor prepared is too long, nickel particles fall off from the surface of matrix, and nano nickel particles grow up due to quick and direct temperature rise can be solved.

Abstract: A robust and general method is provided to synthesize noble metal-based amorphous-crystalline heterophase nanoparticles, each having an amorphous noble metal core and a crystalline semiconductor/metal shell or a Janus structure with an amorphous noble metal domain and a crystalline metal domain attached side by side with the amorphous noble metal domain (i.e., snowman-like structure). The as-synthesized heterophase nanoparticles not only exhibit superior activities in diverse catalytic reactions but also show unexpected high stability, which could be used as ideal templates for the seeded growth of other nanostructures, thus show tremendous potential in different applications including electrocatalysis and photocatalysis. With efficiently separated photo-induced electron and photo-induced holes, superior catalytic performance of amorphous nanomaterials, efficient solar energy conversion ability of crystalline semiconductors, as well as the synergistic effect between them, the controlled construction of amorphous noble metal-crystalline semiconductor heterostructures can be a promising route to development of high-performance catalysts towards photocatalytic reactions.
