Monodisperse supraparticles has been an emerging hot research topic in the fields of chemistry, materials science, and nanotechnology in the past several years. Great attention has been paid to construct monodisperse supraparticles with different sizes, morphologies, and compositions. Their distinctive hierarchical structures and collective properties from various building blocks offer huge benefits towards catalyzing reactions. In this review, we first outline the recent progress on the formation of supraparticles. Afterwards, their applications in photocatalysis, electrocatalysis, and thermal catalysis are summarized. Last, the prospect in this research area is discussed.
