You’ve supercharged your research process with ACS and Mendeley! the hydrazine/ammonia treatment (Hz/NH3) and mixture of authentic ammonia borane (AB) and treated BNHx. These hybrid materials exhibited enhanced catalytic properties (TOF increased up to 2.5 times) compared to individual counterparts or their physical mixture for dehydrogenation of ammonia borane(AB) in non‐aqueous medium(1,4‐dioxane). By continuing you agree to the use of cookies. Herein, NPs were hybridized with UiO‐66(Hf) MOF possessing Brønsted acidic sites (on secondary building units) and fabricated Pd@UiO‐66 (Hf) core–shell and Pd/UiO‐66(Hf) supported catalysts. 0000009215 00000 n When you bring your car to the gas station to fill up, do you cringe a little as you watch the price steadily increase?

The core–shell catalyst exhibited highest activity towards H2 generation from AB owing to greater contact interface between Pd and MOF. 2 Low temperature phase transition studies of ammonia borane-polyacrylamide composites. 0000010124 00000 n It has attracted attention as a source of hydrogen fuel, but is otherwise primarily of academic interest. Adsorption and Dissociation of Ammonia Borane Outside and Inside Single-Walled Carbon Nanotubes: A Density Functional Theory Study. In this paper, ammonia borane was successfully activated by the existence of hybrid alkaline−metal hydrides. In addition, MOFs also can be coated over metal NPs to influence the entire nanoparticle's surface.
