What Techniques are Used to Create Spherical Pores?
Various techniques can be employed to create spherical pores in catalyst materials:
Template Methods: Using spherical templates (e.g., silica or polymer spheres) that are later removed to leave behind spherical cavities. Sol-Gel Processes: Controlling the conditions during sol-gel synthesis to promote the formation of spherical pores. Spray Drying: This method can produce spherical particles with inherent spherical porosity.
