Hübsch dekoriert: Ein Photokatalysator mit Sandwichstruktur katalysiert den Abbau organischer Verbindungen unter UV-Licht, sichtbarem Licht und direktem Sonnenlicht hoch effizient (siehe Bild). Der Katalysator wurde durch Nichtmetalldotierung und Dekoration von TiO2-Nanokristallen mit plasmonischem Metall erhalten, was die Aktivität unter sichtbarem Licht verbessert und die Lichtsammelausbeute bzw. Ladungstrennung erhöht.
