AB  - Aerosol processing is long known and implemented industrially to obtain various 
      types of divided materials and nanomaterials. The atomisation of a liquid 
      solution or suspension produces a mist of aerosol droplets which can then be 
      transformed via a diversity of processes including spray-drying, spray pyrolysis, 
      flame spray pyrolysis, thermal decomposition, micronisation, gas atomisation, 
      etc. The attractive technical features of these aerosol processes make them 
      highly interesting for the continuous, large scale, and tailored production of 
      heterogeneous catalysts. Indeed, during aerosol processing, each liquid droplet 
      undergoes well-controlled physical and chemical transformations, allowing for 
      example to dry and aggregate pre-existing solid particles or to synthesise new 
      micro- or nanoparticles from mixtures of molecular or colloidal precursors. In 
      the last two decades, more advanced reactive aerosol processes have emerged as 
      innovative means to synthesise tailored-made nanomaterials with tunable surface 
      properties, textures, compositions, etc. In particular, the "aerosol-assisted 
      sol-gel" process (AASG) has demonstrated tremendous potential for the preparation 
      of high-performance heterogeneous catalysts. The method is mainly based on the 
      low-cost, scalable, and environmentally benign sol-gel chemistry process, often 
      coupled with the evaporation-induced self-assembly (EISA) concept. It allows 
      producing micronic or submicronic, inorganic or hybrid organic-inorganic 
      particles bearing tuneable and calibrated porous structures at different scales. 
      In addition, pre-formed nanoparticles can be easily incorporated or formed in a 
      "one-pot" bottom-up approach within the porous inorganic or hybrid spheres 
      produced by such spray drying method. Thus, multifunctional catalysts with 
      tailored catalytic activities can be prepared in a relatively simple way. This 
      account is an overview of aerosol processed heterogeneous catalysts which 
      demonstrated interesting performance in various relevant chemical reactions like 
      isomerisation, hydrogenation, olefin metathesis, pollutant total oxidation, 
      selective oxidation, CO2 methanation, etc. A short survey of patents and 
      industrial applications is also presented. Our objective is to demonstrate the 
      tremendous possibilities offered by the coupling between bottom up synthesis 
      routes and these aerosol processing technologies which will most probably 
      represent a major route of innovation in the mushrooming field of catalyst 
      preparation research.
