Abstract
Pada penelitian ini telah berhasil disintesis lapisan tipis AgPt menggunakan metode elektrodeposisi. Fotokatalis AgPt yang dideposisi pada tegangan atas 1,75 V yang dideposisi selama 1 menit memiliki kinerja fotokatalitik yang paling baik karena mampu mendegradasi zat warna metilen biru sebesar 31.76% dan memiliki nilai kapasitansi spesifik yang paling tinggi yakni sebesar 2,96 F/g. Hal ini diakibatkan oleh besarnya komposisi Ag pada fotokatalis yakni sebesar 80,2%. Hal ini karena Ag memiliki efek surface plasmon resonance yang memberikan absorptivitas yang kuat pada sinar tampak dan memicu transfer muatan pada permukaan fotokatalis sehingga mampu meningkatkan aktivitas fotokatalitiknya. AgPt thin film has been successfully synthesize using electrodeposition method. The AgPt photocatalysts deposited at 1.75 V deposited over 1 minute has the best photocatalytic performance because they were able to degrade methylene blue dyes by 31.76% and had the highest benefit capacitance of 2.96 F/g. This could be attributed to the large Ag composition of photocatalysts, which is 80.2% and because Ag has the effect of surface plasmon resonance which provides strong absorption of visible light and charge transfer on the surface of the photocatalyst and enhance its photocatalytic activity.
