Co₂ conversion to methanol over novel carbon nanofiber-based cu/zro₂ catalysts—a kinetics study

Ongoing industrialization has deteriorated the global environment. Global warming is a human-induced issue affecting the environment. The alarming increase in CO₂ emissions is among the major contributors to global warming. The conversion of CO₂ to methanol is an economically viable and environmentally friendly solution to mitigate its concentration. Here, hydrogenation of CO₂ was studied over carbon nanofiber-based Cu/ZrO₂ catalysts. Kinetics investigations were carried out for the reaction. Overall, kinetics data indicated that CO₂ conversion follows a pseudo-first-order reaction. The kinetics studies were further modeled by using an artificial neural network, which supported the experimental kinetics study.
