10 sie 2021 · Co(OH) 2 @NC polyhedron performs more excellent activity and durability compared with noble metal catalysts. In particular, Co(OH) 2 @NC presents excellent OER and ORR catalytic activity by virtue of its unique structure, high porosity and the synergistic catalysis between Co(OH) 2 and nitrogen-doped carbon.
18 maj 2021 · In this work, a secondary-N-doping strategy is developed for enhancing the ORR electrocatalytic performance of Co (OH) 2 /NC, where NC is prepared from pyrolysis of carbon with melamine at 900 °C, then Co (OH) 2 /NC is obtained from depositing Co (OH) 2 nanosheets on NC.
29 sie 2024 · To enhance industrial-scale CO 2-to-C 2 H 4 conversion in an MEA reactor, we introduced activated carbon black (ACB) with different functional groups to manipulate the interfacial...
6 sie 2024 · The activated interface accelerates the OH cycle by enhancing dehydroxylation, water dissociation, and OH adsorption, thereby promoting nitrate electroreduction and inhibiting hydrogen...
We developed metallic phosphide on carbon cloth (FeCoP-CC) as the air cathode for the Na O 2 batteries. •. The FeCoP-CC cathode improves the cycle life (200 cycles) and achieves a discharge capacity (2853 mAh g −1). •. The excellent catalytic activity of FeCoP reduces the overpotential of the Na O 2 battery to 200 mV.
17 mar 2022 · Key mechanistic steps for selective CO(2) reduction over Cu into hydrocarbon versus oxygenated C2 products are identified by atomistic and microkinetic modeling.
25 sie 2017 · A stepwise method was proposed to convert CO 2 and CH 4 into acetic acid over Cu/Co-based catalysts, 2 Pd/C, Pt/Al 2 O 3, 3 Pd/SiO 2, and Rh/SiO 2 4 by heterogeneous catalysis. The catalyst was first exposed to CH 4 , forming CH x species on the catalyst surface.
