Methane pyrolysis on NiMo/MgO catalysts: The significance of equimolar NiMo alloy resisting nanosize segregation during the reaction

Photoelectrochemical water splitting by hematite boosted in a heterojunction with B-doped g-C3N4 nanosheets and carbon nanotubes

“…Carbon nanotubes without any purification were obtained from a catalytic methane decomposition reaction (methane pyrolysis) carried out at 800 °C on supported NiMo/MgO catalysts as reported in our recent research. 46 Be aware that the thin, multiwalled carbon nanotubes may contain a limited amount of spent MoNi 1.2 catalyst sample used to decompose methane. 46 These carbon nanotubes are referred to as p-CNTs, signing that they were obtained as precious by-products of pure, CO x -free H 2 production from methane and subsequently utilized further in these photocatalytic experiments.…”

“…A further, unique feature of our ternary system is that the source of CNT is methane pyrolysis that itself produces turquoise H 2 and economically viable pyrolytic CNT (p-CNT hereafter) as a CO x -free side-product. 46 We could utilize the p-CNT as a versatile conductor material for enhancing the redox capability of the hematite photoanode for the OER. Furthermore, we employed computations to confirm the interfacial band positions at the α-Fe 2 O 3 /B-C 3 N 4 and the α-Fe 2 O 3 /B-C 3 N 4 /CNT interfaces.…”
