Synergistic catalytic hydrolysis of ammonia borane to release hydrogen over AgCo@CN

Abstract

Ag-based materials have features of low-cost and abundance in comparison with Pt-groups metals, while their catalytic performances for hydrogen release from ammonia borane (AB) hydrolysis are relatively low. Herein, we...

Photocatalytic dehydrogenation of ammonia borane over Ti3C2/MOF-supported Pd-doped Co nanoparticles

“…Thus, the relationship between the logarithm of the rate and the logarithm of the catalyst dose was almost linear with a slope of 0.999, indicating a first-order reaction with regard to the catalyst. 47 The slope of the ln rate versus ln[AB] was found to be 0.019 (Fig. 3b), indicative of a zero -order reaction in respect of the substrate.…”

Architecture engineering toward highly active Rh integrated porous carbon with diverse flexible channels for hydrogen evolution

“…2(e)). 18,36,58 Besides, the Rh 3d HR-XPS spectrum revealed two groups of doublets indexing to metallic Rh 0 (307.8/312.4 eV) and Rh n + (309.3/313.9 eV) (Fig. 2(f)), respectively.…”

“…[28][29][30] To efficiently control the particle size and dispersion of active components, carbon-based matrices are designed and investigated as carriers. [31][32][33][34][35][36][37] Architecture engineering of carbon matrices is a feasible way to regulate the pore structure and surface-exposed active sites of catalysts. In particular, hollow nanostructured carbon materials have been exploited to anchor and disperse active components to achieve high catalytic activity.…”

Highly electron-deficient ultrathin Co nanosheets supported on mesoporous Cr2O3 for catalytic hydrogen evolution from ammonia borane

“…13,14 Recently, introducing light irradiation in the reaction system has emerged as an effective strategy to enhance the activity of catalysts and accelerate the H 2 evolution rate from NH 3 BH 3 hydrolysis catalyzed by supported catalysts. Supported catalysts such as typical Mott–Schottky catalysts composed of a metal and semiconductor such as Ru/β-SiC, 15 Ni x Cu y /CNS, 16 Au–Co@CN, 17 AgCo@CN, 18 Co/PCN, 19 Ru 0.85 Pd 0.15 /g-C 3 N 4 , 20 Co/F-CeO 2 , 21 and Co/CoFe-Mo 22 have been employed for the hydrolysis of NH 3 BH 3 under light irradiation. Enhanced catalytic performance has been achieved by increasing the electron density of active metals due to the Schottky effect.…”
