TL;DR: A size-dependent activity in Pt/CNT catalyzed hydrolytic dehydrogenation of ammonia borane is reported and the insights reported here may pave the way for the rational design of highly active and durable Pt catalysts for hydrogen generation.

TL;DR: An unprecedented H2 generation activity is demonstrated in the hydrolytic dehydrogenation of ammonia borane over acid oxidation- and subsequent high temperature-treated CNT immobilized Pt nanocatalysts to combine the merits of defect-rich and oxygen group-deficient surfaces and unique textural properties of supports as well as optimum particle size of Pt.

TL;DR: In this article, the authors performed first-principles calculations to determine the preferred adsorption sites and the adsorbing energies of NHx (x = 0-3) and H, and identified the transition states of the NH3 stepwise dehydrogenation reactions and the N recombination reactions on the close-packed Fe(1, 1, 0), Co(1, 1, 1), Ni(1 −1), and Ni( 1 −1) surfaces.

TL;DR: After promotion using an appropriate amount of sulfur, iron catalysts exhibit not only enhanced Fischer-Tropsch synthesis activity and selectivity toward lower olefins, but also increased resistance against carbon deposits.

TL;DR: In this paper, two kinds of Co-Mo bimetallic catalysts (i.e., CoMo-I/γ-Al2O3 and CoMo II/γγ-al 2O3) prepared by using different active phase precursors as well as Co and Mo monometric catalysts were used to catalyze ammonia decomposition.
