AB  - The World Health Organization reports that every year several million people die 
      prematurely due to air pollution. Poor air quality is a by-product of 
      unsustainable policies in transportation, energy, industry, and waste management 
      in the world's most crowded cities. Particulate matter (PM) is one of the major 
      element of polluted air. PM can be composed by organic and inorganic species. In 
      particular, heavy metals present in PM include, lead (Pb), mercury (Hg), cadmium, 
      (Cd), zinc (Zn), nickel (Ni), arsenic (As), and molybdenum (Mo). Currently, 
      vegetation is the only existing sustainable method to reduce anthropogenic PM 
      concentrations in urban environments. In particular, the PM-retention ability of 
      vegetation depends on the surface properties, related to the plant species, leaf 
      and branch density, and leaf micromorphology. In this work, a new hybrid material 
      called SUNSPACE (SUstaiNable materials Synthesized from by-Products and Alginates 
      for Clean air and better Environment) is proposed for air PM entrapment. Candle 
      burning tests are performed to compare SUNSPACE with Hedera Helix L. leafs with 
      respect to their efficacy of reducing coarse and fine PM. The temporal variation 
      of PM(10) and PM(2.5) in presence of the trapping materials, shows that Hedera 
      Helix L. surface saturates more rapidly. In addition, the capability of SUNSPACE 
      in ultrafine PM trapping is also demonstrated by using titanium dioxide 
      nanoparticles with 25 nm diameter. Scanning electron microscope (SEM) and 
      Transmission electron microscope (TEM) images of SUNSPACE after entrapment tests 
      highlight the presence of collected nanoparticles until to about 0.04 mm in depth 
      from the sample surface. N(2) physisorption measurements allow to demonstrate the 
      possibility to SUNSPACE regeneration by washing.
