I-TiO2 / i-Perlite composite

Isicelo se-Ultrasonic:
Izinto zokuhlanganiswa ze-TiO2 / perlite zaziyizinto ezilungiselelwe. Ekuqaleni, i-5 mL titanium isopropoxide (i-TIPO), i-Aldrich 97%, yachithwa e-ethanol engu-40 mL, iCarlo Erba, futhi yavuselela imizuzu engu-30. Khona-ke, 5 g perlite yanezelwa futhi ukuhlakazeka kwavuthwa ngamaminithi angu-60. Le nhlanganisela yayiqhutshwa phambili nge-homogenized ngokusebenzisa i-ultraicound tip sonicator I-UIP1000hd. Ukufakelwa kokusebenza kwamandla kwe-Wh okungu-1 kusetshenziswe isikhathi sokunikezela nge-2 min. Ekugcineni, i-slurry yahlanjululwa nge-ethanol ukuthola ukumiswa kwamamitha angu-100 futhi uketshezi olutholakali lwaphakanyiswa njengesisombululo se-precursor (PS). I-PS elungiselelwe yayilungele ukucubungulwa ngesistimu ye-flame spray pyrolysis.
