In this study, the catalytic performance of a novel material with high activity and reusability in the catalytic decomposition of methylamine borane (MeAB) is presented. The rhodium(0)-loaded UiO-67 solid-supported catalyst (Rh@UiO-67) was prepared using the wet impregnation and reduction method. The synthesized Rh@UiO-67 catalyst was characterized by various spectroscopic and microscopic techniques, including ICP-OES, XRD, XPS, FE-SEM, and SEM-EDX. The catalytic activity of Rh@UiO-67 in the complete decomposition of methylamine borane (MeAB) was investigated under ambient conditions (50 °C, open air). The results demonstrated that the catalyst achieved 100% conversion with a high turnover frequency (TOF) of 149.49 min⁻¹. These findings indicate that Rh@UiO-67 is an efficient and reusable catalyst for the complete decomposition of MeAB.

Metilamin Boranın Hidroliz Tepkimesi İçin Rodyum Yüklü UiO-67’nin Sentezi, Karakterizasyonu ve Katalitik Performansının İncelenmesi

Öz

Bu çalışmada, metilamin boran (MeAB) katalitik bozunma reaksiyonunda yüksek aktivite ve tekrar kullanılabilirlik özellikleriyle öne çıkan yeni bir malzemenin katalitik performansı açıklanmaktadır. Rodyum(0) yüklü UiO-67 katı destekli katalizör (Rh@UiO-67), ıslak emdirme ve indirgeme yöntemiyle hazırlanmıştır. Hazırlanan Rh@UiO-67 katalizörü, ICP-OES, P-XRD, XPS, FE-SEM ve SEM-EDX gibi çeşitli spektroskopik ve mikroskobik teknikler kullanılarak karakterize edilmiştir. Rh@UiO-67 katalizörünün, metilamin boran (MeAB) bileşiğinin tam katalitik bozunma reaksiyonu üzerindeki etkinliği 25 °C’de ve açık hava koşullarında incelenmiştir. Yapılan çalışmalar, katalizörün %100 dönüşüm sağlayarak 149.49 dk⁻¹ gibi yüksek bir çevrim frekansı (TOF) sergilediğini göstermiştir. Bu sonuçlar, Rh@UiO-67'nin MeAB’nin bozunmasında etkili ve tekrar kullanılabilir bir katalizör olduğunu ortaya koymaktadır.
