Temperture-programmed reduction (H2-TPR) of Ni-Mo2CTx_Mo2Ga2C and Ni-Mo2CTx_Mo3AlC2 catalysts

The dataset includes the data for the preparation of plots illustrating the reduction peaks versus the temperature of the catalyst sample.
The parameters of H2-TPR analysis using In-situ Catalyst Characterization System PID purchased from Micrometrics Company:
- start temperature: 100 deg. C,
- end temperature - 900 deg. C,
- temperature rise 10 deg. C per minute
-pretreatment at 100 deg. C under helium for 60 min.
 Details of sample preparation of Ni-Mo2CTx_Mo2AlC3:
1 st step: MXene material was prepared via selective etching of aluminium using hydrofluoric acid (50%) for 96 h at room temperature. After the etching, the powders were flirted and washed with water and ethanol until pH reached 6. Then, the MXene was dried under vacuum at 50˚C for 24 h.
2 nd step: Nickel catalyst was prepared via impregnation of previously prepared Mo2CTx/Mo2AlC2 with aqueous nickel nitrate solution and drying at 50 deg. C under vacuum.
Details of sample preparation of Ni-Mo2CTx_Mo2Ga2C:
1 st step: The preparation procedure for Mo2CTx/Mo2GaC:
1) Etching of Mo2Ga2C with XF/HCl mixture (where X= Na, Li, K) under hydrothermal conditions at 90 deg. C for 24 or 48 hours.
2) Washing with water.
3) Dring at 50 deg. C under vacuum.
2nd step: The preparation procedure for Ni-Mo2CTx/Mo2GaC:
1) Impregnation of previously prepared Mo2CTx/Mo2GaC with aqueous nickel nitrate solution. 
2) Dring at 50 deg. C under vacuum.
