Bu çalışmada, titanium dioksit (TiO₂) ve karbon nanotüp (CNT) nanopartikülleri içeren polivinil alkol (PVA) nanolifler, elektroeğirme yöntemi ile hazırlanmıştır. Kompozit nanoliflerin UV radyasyonu altındaki katı-faz fotokatalitik bozunma özelliği, ağırlık kaybı ölçümleri ile incelenmiştir ve saf PVA nanoliflerin fotokatalitik özelliği ile karşılaştırılmıştır. FTIR spektroskopi ve termogravimetrik analizleri kullanılarak, TiO₂ and CNT nanopartiküllerinin PVA nanolif yapısına katıldığı tespit edilmiştir. SEM analizine göre, TiO₂ and CNT katkısı ile PVA nanoliflerin çaplarında incelme eğilimi görülmüştür. Ayrıca, PVA nanolifler ile karşılaştırıldığında, kompozit nanoliflerin UV radyasyonu altındaki katı-faz fotokatalitik bozunma verimi daha yüksektir.
