Engineering VO-Ti ensemble to boost the activity of Ru towards water dissociation for catalytic hydrogen generation

Embedded Ruthenium Nanoparticles within Exfoliated Nanosheets of Ti3C2Tx for Hydrogen Evolution

“…After Ru incorporation, more O vacancies were achieved, suggesting its enhanced oxophilicity associated with abundant defects present on the surface, especially for Ru@M-OH, which was consistent with the EPR observation. According to previous reports, O vacancies always improved the HER activity, and thus we expected that the as-synthesized Ru@M-OH could promote hydrogen production.…”

Functional Group Regulated Ni/Ti3C2Tx (Tx = F, −OH) Holding Bimolecular Activation Tunnel for Enhanced Ammonia Borane Hydrolysis

“…The increasing mass of catalyst Ni/Ti 3 C 2 T x -4 (5−15 mg) significantly boosted the rate of hydrogen generation from AB hydrolysis ranged from 34 to 116 L•min −1 •g −1 (SI Figure S11a,b). 47 The curves of time versus hydrogen volume catalyzed by different masses of AB (22, 34 and 46 mg) are shown in SI Figure S12a,b. The concentration of AB in the catalytic system regulated with the change of AB mass.…”

Ammonia borane as an efficient direct fuel in alkaline fuel cells: mechanism, catalysts, applications, and challenges

“…39 The authors studied the morphologies and electrochemical performance of carbon-supported catalysts Ni Non-noble metal catalysts. Owing to their low cost, abundant resources, good conductivity, and promising electrocatalytic activity, transition metals have been widely studied and applied in the electrocatalytic eld such as the oxygen reduction reaction (ORR), [63][64][65][66][67] oxygen evolution reaction (OER), [68][69][70][71][72] hydrogen evolution reaction (HER), [73][74][75][76] electrocatalytic nitrogen and CO 2 reduction reactions (NRR 77,78 and CO 2 RR [79][80][81] ). Therefore, researchers also explore transition metal-based electrocatalysts for the direct electrooxidation of AB.…”
