The present study developed bifunctional catalyst for CO2 hydrogenation into di-Me ether (DME), whereby it consists of Pd/In2O3 for CO2 hydrogenation into methanol, and H-ZSM-5 for methanol dehydration into DME. The catalyst development was focused on the synthesis of Pd/In2O3 via a green and low-cost synthesis method of carbonized alginate templating. Thus, microspherical-confined nano-Pd/In2O3 was formed, whereby the localized nucleation growth was coordinated by the chem. entrapped In3+ via ionic bond in the well-distributed alginate structure. It was found that hydrothermal temperature plays a key role in the development of this catalyst structure. The optimum hydrothermal temperature is 160°C, as it is able to produce the highest amount of methanol. This catalyst was further integrated with H-ZSM-5 via different integration manners. It was found that mortar mixed method produces the highest amount of DME, as the close proximity causes stronger ion-exchange mechanism between the catalyst components, which facilitates higher oxygen vacancy d. in the bifunctional catalyst. Under the optimum Pd/In2O3: H-ZSM-5 (PdIn-160-12: H-ZSM-5) mass ratio of 4:1, the highest STYDME of 79.7 gDME kg-1cat h-1 with CO2 conversion of 9% and DME selectivity of 44.1% can be achieved. In addition, the STYDME can be maintained even in 60 h on stream, demonstrating the excellent stability and performance of microspherical-confined nano-Pd/In2O3/H-ZSM-5 bifunctional catalyst synthesized via carbonized alginate templating strategy. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6HPLC of Formula: 13820-53-6).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.HPLC of Formula: 13820-53-6
