A new reactivation method towards deactivation of honeycomb ceramic monolith supported cobalt-molybdenum-boron catalyst in hydrolysis of sodium borohydride

The honeycomb ceramic monolith supported Co-Mo-B catalyst exhibits an excellent activity for hydrolysis of NaBH4, but it gradually deactivates over the cycles. Low temperature calcination treatment at 120 °C in air was found to be an effective reactivation method towards the deactivation of catalyst.164
