Clarifying the catalytic role of NiO nanoparticles in the oxidation of asphaltenes

- Abu Tarboush and Husein overlooked and misinterpreted our work.
- We point out an erroneous TG/DTA data interpretation by these authors.
- Their suggested “surface effect” and “multilayer oxidation” concepts do not apply to our study.
- These concepts lack sufficient evidence at this point and not supported by their own data.
- Role of our NiO nanoparticles is catalytic not surface exposure.
