Abstract

We report the synthesis of carbon quantum dots supported-Co (Co@CQDs) catalyst and its catalytic activity. The synthesized Co@CQDs catalyst for the first time is used to obtain the maximum hydrogen production rate from hydrolysis of NH₃BH₃. The synthesized Co@CQDs catalyst indicates a compelling performance in the hydrogen production from the hydrolysis of NH₃BH₃. It is found that Co@CQDs with the loading of Co (10 wt%) indicates a hydrogen production rate of 18600.27 mL/min.g_cat and low activation energy of 22.97 kJ mol^{− 1}. The current study demonstrates that CQDs are promising support for dispersing metal catalysts. Moreover, the synthesized Co@CQDs catalyst is characterized by X-ray diffraction, ultraviolet and visible light, photoluminescence, inductively coupled plasma optical emission spectrometry, and transmission electron microscope measurements.
