Photocatalytic Hydrogen Production by CuS/CuInS2/TiO2: Effect of Photocatalyst Synthesis Method

Abstract

Photocatalytic hydrogen production is known as a clean and renewable energy production process with significant potential to convert solar energy into chemical energy by using suitable photocatalysts. In this study, it was aimed to synthesize CuS/CuInS2/TiO2 nanocomposite to increase H2 production under solar light. CuS/CuInS2/TiO2 was prepared by two different synthesis methods, solid-solid synthesis and in situ synthesis; the photocatalyst composition and photocatalyst synthesis method with the highest H2 production were determined.

CuS/CuInS2/TiO2 ile Fotokatalitik Hidrojen Üretimi: Fotokatalizör Sentez Yönteminin Etkisi

Abstract

Fotokatalitik hidrojen üretimi, uygun fotokatalizörler kullanılarak güneş enerjisini kimyasal enerjiye dönüştürme konusunda önemli bir potansiyele sahip, temiz ve yenilenebilir bir enerji üretim süreci olarak bilinmektedir. Bu çalışmada, solar ışık altında H2 üretimini arttırmak için CuS/CuInS2/TiO2 nanokompozitinin sentezlenmesini hedeflenmiştir. CuS/CuInS2/TiO2 katı-katı sentez ve yerinde sentez olmak üzere iki farklı sentez metodu ile hazırlanmıştır; H2 üretiminin en yüksek olduğu fotokatalizör kompozisyonu ve fotokatalizör sentez metodu belirlenmiştir.
