الملخص

نظرًا لخصائصها الكهربائية الفريدة، فقد جذبت عائلة المواد ثنائية الأبعاد الجديدة المعروفة باسم MXenes الكثير من الاهتمام. يعد كربيد الفاناديوم (V2C) أحد أهم MXenes التي يتم النظر فيها نظرًا لمزاياه العديدة مقارنة بالمواد الأخرى. في هذا العمل، تم تصنيع مركبات TiO2 المحملة بـ V2C واختبارها للاختزال الضوئي لثاني أكسيد الكربون باستخدام الماء لإنتاج وقود CO وCH4 ذي القيمة المضافة في نظام مفاعل ضوئي مستمر التدفق. سمحت الموصلية المتزايدة والعدد الكبير من المواقع النشطة وامتصاص الضوء الأعلى بالفصل الفعال لحاملات الشحنة وامتصاص الضوء. كان 10٪ V2C-TiO2 المحسن مسؤولاً عن تكوين CO وCH4 بمقدار 1233.8 و 85.2 ميكرومول جرام-1 ساعة-1 على التوالي، والتي كانت أعلى بكثير من استخدام TiO2 النقي. من الواضح أن الزيادة في كفاءة التحفيز الضوئي كانت بسبب منع إعادة تركيب الشحنة بفضل فصل الشحنة بكفاءة في وجود بنية طبقية ثنائية الأبعاد من V2C MXene.
