Abstract
- Exploring the applications of two dimensional layered Ti<subscript>3</subscript>C<subscript>2</subscript>X<subscript>2</subscript> (X = OH, F) is of great importance because of its excellent physical and chemical properties. Herein, we report the synthesis of the bimetallic catalyst Pt<subscript>y</subscript>Co<subscript>1−y</subscript>/Ti<subscript>3</subscript>C<subscript>2</subscript>X<subscript>2</subscript>via a facile one-pot approach using Ti<subscript>3</subscript>C<subscript>2</subscript>X<subscript>2</subscript> as the support. The in situ synthesized Pt<subscript>y</subscript>Co<subscript>1−y</subscript>/Ti<subscript>3</subscript>C<subscript>2</subscript>X<subscript>2</subscript> is subsequently applied as a catalyst for hydrogen evolution from the hydrolysis of ammonia borane at 25 °C. Experimental results show that Pt<subscript>0.08</subscript>Co<subscript>0.92</subscript>/Ti<subscript>3</subscript>C<subscript>2</subscript>X<subscript>2</subscript> exhibits excellent catalytic activity for the hydrolysis of ammonia borane with a high hydrogen generation rate of 100.7 L H<subscript>2</subscript> (min g<subscript>Pt</subscript>)<superscript>−1</superscript> and turnover frequency of 727 mol H<subscript>2</subscript> (min mol<subscript>Pt</subscript>)<superscript>−1</superscript> because of the synergistic effect between Pt and Co. Moreover, Pt<subscript>0.08</subscript>Co<subscript>0.92</subscript>/Ti<subscript>3</subscript>C<subscript>2</subscript>X<subscript>2</subscript> could be recovered from the reaction mixture by a magnet and recycled at least seven times, thus showing its high recycling efficiency.
