Abstract

A cost-effective and reusable catalyst, manganese(II) bromide supported on activated carbon (MnBr₂/AC), was developed for the controlled dehydrogenation of sodium borohydride (NaBH₄) under alkaline conditions. The system exhibited stable hydrogen release at 22 °C in 1 M NaOH solution, achieving 98.3 % hydrogen yield and maintaining activity over 14 cycles with zero-order kinetics. The MnBr₂/AC catalyst provides a simple, durable, and scalable approach for long-term hydrogen generation.

Özet

Alkali koşullar altında sodyum borohidrürün (NaBH₄) kontrollü dehidrojenasyonu için, aktif karbon destekli mangan(II) bromür (MnBr₂/AC) temelli, maliyet etkin ve yeniden kullanılabilir bir katalizör geliştirilmiştir. Sistem, 1 M NaOH çözeltisinde 22 °C’de kararlı hidrojen salınımı göstermiş, %98,3 hidrojen verimine ulaşmış ve sıfırıncı mertebeden kinetik davranış sergileyerek 14 çevrim boyunca etkinliğini korumuştur. MnBr₂/AC katalizörü, uzun süreli hidrojen üretimi için basit, dayanıklı ve ölçeklenebilir bir yaklaşım sunmaktadır.
