To evaluate their catalytic activity, we reacted the TNTs and Pt/TNTs photocatalytically with carbon monoxide (CO). These investigations indicated that the efficient removal of CO could be attributed to the high dispersion of Pt on the TNT (123.4 m2/g, 0.39 cm3/g). Pt/TNT(C) displays a high CO conversion activity of about 99%, which is superior to that of P25. The CO conversion was optimum when the reaction was performed at room temperature with an O2 concentration of 10%, a CO concentration of 500 ppm, and a space velocity of 1.79×104 h-1.4enjournal article
