TL;DR: Control experiments indicate that during catalyst preparation the presence of Na2SO4 and Na2S is beneficial for the in-situ transformation of Co3O4 into catalytically active Co-B alloys accompanying with positive change in surface morphology during the NaBH4 hydrolysis, thereby inducing excellent hydrogen generation rate of up to 4425 mL·min-1·gcat-1.
Abstract: Development of a simple and efficient strategy for improving the catalytic activity of cobalt-based catalysts toward hydrogen evolution from sodium borohydride (NaBH4) is paramount but remains challenging. Here, we reported a facile and efficient approach to tune the catalytic performance for NaBH4 hydrolysis with Co-based catalysts prepared by using cobalt sulfate as a precursor or a mixture of sulfur-containing sodium salts/cobalt salts as a raw material. With the use of cobalt sulfate as the precursor, the CoSO4-doped Co3O4 sample was formed and it exhibited excellent activity with the generation of ∼500 mL of hydrogen gas from NaBH4 hydrolysis under mild conditions. In terms of sulfur-free cobalt salts (e.g., cobalt chloride, cobalt nitrate, and cobalt acetate) as precursors, the obtained Co-based samples were found to be entirely ineffective for hydrogen production. Interestingly, during the cobalt-based catalyst preparation, the introduction of sodium sulfate or sodium sulfide can considerably accelerate hydrogen production. On the contrary, adding sulfur-bearing salts did not inspire any activity improvement only during the hydrogen generation reaction. Control experiments indicate that during catalyst preparation, the presence of Na2SO4 and Na2S is beneficial for the in situ transformation of Co3O4 into catalytically active Co-B alloys, accompanying a positive change in surface morphology during the NaBH4 hydrolysis, thereby inducing an excellent hydrogen generation rate of up to 4425 mL·min-1·gcat-1.

TL;DR: In this article, the bimetallic catalyst PtyCo1−y/Ti3C2X2 was synthesized using a facile one-pot approach using Ti3C 2X2 as the support.
Abstract: Exploring the applications of two dimensional layered Ti3C2X2 (X = OH, F) is of great importance because of its excellent physical and chemical properties. Herein, we report the synthesis of the bimetallic catalyst PtyCo1−y/Ti3C2X2via a facile one-pot approach using Ti3C2X2 as the support. The in situ synthesized PtyCo1−y/Ti3C2X2 is subsequently applied as a catalyst for hydrogen evolution from the hydrolysis of ammonia borane at 25 °C. Experimental results show that Pt0.08Co0.92/Ti3C2X2 exhibits excellent catalytic activity for the hydrolysis of ammonia borane with a high hydrogen generation rate of 100.7 L H2 (min gPt)−1 and turnover frequency of 727 mol H2 (min molPt)−1 because of the synergistic effect between Pt and Co. Moreover, Pt0.08Co0.92/Ti3C2X2 could be recovered from the reaction mixture by a magnet and recycled at least seven times, thus showing its high recycling efficiency.
