Abstract

Bu çalışmada ilk kez kahve çekirdeği atığından (kahve telvesinden) elde edilen aktif karbon kullanılarak CuMoB@AC ilk kez katalizörü sentezlendi. Burada en iyi katalitik performanslarını belirlemek amacıyla; Cu:Mo oranı, Metal/AC oranı, optimum NaOH oranı, katalizör miktarı, en uygun NH 3 BH 3 oranı ve farklı sıcaklıklarda yapılan deneyler sonucunda da reaksiyon kinetiği çıkarılarak reaksiyonun derecesinin n. dereceden (0.9) olduğu ve aktivasyon enerjisinin de 34,89 kJ/mol olduğu belirlendi. Aynı zamanda katalizörümüz karakterizasyonu belirlemek için SEM-EDS, XRD ileri analitiksel yöntemler kullanılarak belirlenmiştir.

Investigation of a cheap and useful activated carbon supported catalyst in ammonia boron hydrolysis

Abstract

In this study, CuMoB@AC catalyst was synthesized for the first time by using activated carbon obtained from coffee bean waste (coffee grounds). In order to determine the best catalytic performances; Cu:Mo ratio, Metal/AC ratio, optimum NaOH ratio, catalyst amount, optimum NH3BH3 ratio and reaction kinetics were determined as a result of experiments performed at different temperatures. It was determined that the degree of the reaction was n. degree (0.9) and the activation energy was 34.89 kJ/mol. At the same time, our catalyst was determined using SEM-EDS, XRD advanced analytical methods to determine the characterization.
