چکیده

در این پژوهش، از دو اتصال ناهمگون BiFeO3 که با استفاده از روشهای کم هزینه و آسان سنتز شدند به منظور تولید هیدروژن طی واکنش کلی شکافت فتوکاتالیستی آب استفاده شد. به همین منظور از آنالیزهای XRD، FTIR،FESEM ،PL  و UV-Vis برای شناسایی خواص ساختاری و نوری فتوکاتالیست‌های سنتز شده استفاده گردید. واکنش مورد نظر در یک راکتور از جنس کوارتز با حجم mL 160 تحت نور فرابنفش انجام گرفت. علی‌رغم اینکه میکرومکعب‌های پروسکایت BiFeO3، نانوذرات g-C3N4 و نانوورقه‌های ZnS به تنهایی قادر به انجام موثر واکنش شکافت آب نبودند، نمونه‌های کامپوزیتی فعالیت فتوکاتالیستی بسیار مطلوبی از خود نشان دادند. بالاترین نرخ تولید هیدروژن  معادل µmol.g-1.h-1 160 است که از نمونه بهینه به دست آمد.

چکیده [English]

In this research, the improved heterojunction of BiFeO3 were synthesized by a facile and cost-effective method, for hydrogen generation through photocatalytic overall water splitting. Moreover, XRD, FTIR, FESEM, PL, and UV-vis were applied to characterize the structural and optical properties of the synthesized samples. The photocatalytic reactions were carried out in a quartz photoreactor with effective volume of 160 mL exposed to UV irradiation. In spite of the fact that the perovskite type BiFeO3 micro cube, g-C3N4 nanoparticles and ZnS nanosheets were not capable for hydrogen generation significantly, the composite samples showed the favorable photocatalytic activity. The highest rate of hydrogen production was about 160 μmol.h-1.g-1, and it was obtained by optimal sample.
