	Title	Platinum nanoparticles confined within TiO2 nanotube matrix for enhanced catalytic reduction of azure b dye			Type
	Year	2023	Publication	Materials Letters	Abbreviated Journal	Mater. Lett.
	Volume	330	Issue		Pages	133208
	Keywords	PtNPs-TiO2NTs; Catalytic reduction; Azure B; Pseudo-first order reaction
	Abstract	In this work, we report the synthesis of TiO2 nanotubes encapsulated platinum nanoparticles (PtNPs-TiO2NTs) as a highly efficient catalyst for the catalytic reduction of azure B (AZB) dye in the sodium borohydride (NaBH4) medium. The encapsulation of PtNPs (particle size similar to 2-3 nm) inside the TiO2NTs was confirmed by HR-TEM analysis. The as-prepared PtNPs-TiO2NTs exhibit higher conversion efficiency than 99 % with a pseudo-first order rate constant of 2.6 x 10(-3) s(-1). Owing to the confinement effect of PtNPs inside the TiO2NTs, the synthesized catalyst shows the superior operative stability even after 8 consecutive recycles without any loss in its activity. This work opens up new avenue for the designing of confined catalyst for various industrial catalytic reactions.
