“…A variety of nano/micromaterials have been continuously synthesized in a microreactor. The as‐prepared materials can be simply classified into inorganic single‐component micro/nanoparticles (e.g., Ag, Au, Pd, CdS, layered double hydroxides, ZIF‐8, In(OH) 3 ), inorganic micro/nanocomposites (e.g., Ag@Cu 2 O, MOF@SiO 2 ), and polymeric‐based materials . In the case of single‐component micro/nanoparticles, considerable efforts have been devoted to achieve how to manipulate the particle size and morphology of micro/nanoparticles.…”
