High Voltage Discharge

Some catalytic materials can be utilized in environment pollution treatment. The material of ceramisite can be used in dye wastewater treatment process with its good properties. When they were filled in the high voltage discharge reactor, the ceramsite pellets were polarized, and partial discharge could take place beside every pellet, which would promote methylene blue degeneration in the dye wastewater. And when the solution pH>ceramsite pHzpc, the ceramsite surface presented the electronegativity and the ceramsite could adsorb more methylene blue, and removal rate increased.

Electrochemical Wacker oxidation of terminal olefins has been among the most interesting reactions from an industrial standpoint. However, the poor regioselectivity and contamination of products with palladium (Pd) catalysts have been the main drawbacks of its commercialization. Herein, rational preparation, as well as catalytic, structural, and electrochemical properties analysis of solid-supported Pd on graphene nanoplatelets (GNP) highly active catalysts for regioselective Wacker-type electrooxidation of terminal olefins is presented. The prepared catalysts improved by two orders of magnitude the electrocatalytic oxidation of 1-octene compared to the conventional homogeneously-catalyzed reactions. The control over oxidation regioselectivity via minimization of the cathodic reduction reaction was also confirmed.To be presented at: the 235th ECS Meeting, Dallas, TX. May 26-31, 2019.

A novel gold catalyst supported by In2O3-ZrO2 with a solid solution structure shows a methanol selectivity of 70.1% and a methanol space–time yield (STY) of 0.59 gMeOH h−1 gcat−1 for CO2 hydrogenation to methanol at 573 K and 5 MPa. The ZrO2 stabilizes the structure of In2O3, increases oxygen vacancies, and enhances CO2 adsorption, causing the improved activity.
