Catalytic performance of calcium titanate for catalytic decomposition of waste polypropylene to carbon nanotubes in a single-stage cvd reactor

Modekwe, Helen Uchenna; Mamo, Messai Adenew; Daramola, Michael Olawale; Moothi, Kapil (MDPI, 2020-09)

Calcium titanate mixed metal oxides with different contents were used as supports for NiMo catalyst prepared by the sol–gel method. The activities of these catalysts were tested in the catalytic decomposition of waste ...
Effect of different catalyst supports on the quality, yield and morphology of carbon nanotubes produced from waste polypropylene plastics

Modekwe, Helen Uchenna; Mamo, Messai Adenew; Moothi, Kapil; Daramola, Michael Olawale (MDPI, 2021-06)

The role of the effect of the support on the reactivity of heterogeneous catalysts cannot be over-emphasized. Therefore, the study documented in this article investigated the effect of different metal oxide supports (MgO, ...
