Synergistic effect of Co catalysts with atomically dispersed CoN_x active sites on ammonia borane hydrolysis for hydrogen generation

Abstract

The development of low-cost, highly efficient and durable catalysts is the key to the practical use of ammonia borane as a promising storage material for on-board hydrogen production. Atomically dispersed...

Co–MoCx supported on N-doped CNTs for efficient hydrogen evolution reaction under alkaline medium conditions

“…As determined by XANES analysis in our previous results, Co/N-CNTs could present certain amounts of Co-SAs on the CNT, together with the Co NPs. 24…”

Recent progress in porous catalysts for dehydrogenation of ammonia borane

“…The catalytic performance of Pt@NiO/Ni-CNT was studied for hydrolysis of AB against the reference catalysts, and the Pt@NiO/Ni-CNT catalyst exhibited a high catalytic rate with B41. 112 reported Co NPs loaded on the CNT support with atomically dispersed CoN x active sites as low-cost, highly efficient and durable catalysts for AB hydrolysis (Fig. 6e).…”

“…This work suggested that the engineering of the interfacial structure of bimetal catalysts plays an important role in improving synergistic catalytic performances. Poon et al 112 reported Co NPs loaded on the CNT support with atomically dispersed CoN x active sites as low-cost, highly efficient and durable catalysts for AB hydrolysis (Fig. 6e).…”

Cobalt catalysts (Co–N–C) for C–O bond cleavage in lignin-derived aryl ethers and lignin

“…Additionally, atomically dispersed metal-supported catalysts maximize the efficiency of metal utilization and act as a robust support for metal nanoparticles. 18 M-N-C (Fe, Co, and Ni) single-atom catalysts (SACs) with metals strongly linked to surrounding N atoms have shown promising performances in electrochemical 19 and thermochemical reactions. 20…”
