description The two-dimensional transition metal carbides and carbonitrides (MXene) based catalyst has excellent catalytic activity for the hydrolysis and hydrogen production reaction. The ultra-highly dispersed metal rhodium (Rh) supported by two-dimensional titanium carbide (Ti<sub>3</sub>C<sub>2</sub>T<sub><i>x</i></sub> MXene) catalyst (Rh/Ti<sub>3</sub>C<sub>2</sub>T<sub><i>x</i></sub> MXene) was prepared by <i>in-situ</i> reduction method. The high dispersion of Rh sub-nano clusters is achieved by using the highly exposed surface of a single layer two-dimensional Ti<sub>3</sub>C<sub>2</sub>T<sub><i>x</i></sub> MXene materials. The as-prepared Rh/Ti<sub>3</sub>C<sub>2</sub>T<sub><i>x</i></sub> MXene catalyst is used for the normal temperature decomposition of ammonia borane under normal pressure and mild conditions. Ammonia borane can completely release hydrogen within 3 minutes under the conditions of 35℃ and 0.1 MPa. The structural characterization of the catalyst proves that the average size of Rh sub-nano clusters is about 0.66 nm. The structure-activity correlation study shows that the highly exposed carbon-titanium bond (C-Ti) structures on the surface of the two-dimensional Ti<sub>3</sub>C<sub>2</sub>T<sub><i>x</i></sub> MXene carrier can play a role in anchoring and highly dispersing Rh sub-nano clusters.
