As global warming caused by CO2 emission is becoming a serious issue that is threatening our life, various efforts have been attempted to mitigate the climate change by reducing the CO2 emission. The primary objective of this project is to develop a novel Pd-based heterogeneous catalyst to enhance the catalytic conversion of CO2 by H2 for the synthesis of value-added chemicals such as CO, methanol and fuels. The Pd-based solution we developed can be tuned to be either acidic or basic to adapt to different catalyst support. The solution was characterized by Ultraviolet-visible spectroscopy and the band adsorption for Pd species was observed. The heterogeneous catalyst was synthesized on alumina support (acidic) and active carbon support (basic) via Wet Incipient Impregnation method. The synthesized catalyst is to be tested for CO2 hydrogenation and the catalyst characterization such as Brunauer Emmett Teller (BET) surface area, pore size and volume, Transmission Electron Microscope (TEM), and X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) to be conducted with an aim to establish a relationship between activity and properties. This fundamental study will serve as guidance for us to understand the reaction pathway of CO2 hydrogenation.
