A partial oxidation process of hydrocarbons is provided, including bringing an inlet gas into contact with a catalyst, the inlet gas including a hydrocarbon raw material gas and a hydrogen chloride gas, wherein the catalyst includes a catalyst material including palladium (Pd), which catalyst material is supported on a carrier including cerium oxide (CeO) and an amount of catalyst material supported on the carrier is 2 wt % to 10 wt % based on a total weight of the catalyst.

Partial oxidation process of hydrocarbons

Provided is an electrode for electrolysis and a preparation method of the same. The electrode for electrolysis has an improved needle-like structure of a rare earth metal compared to conventional electrodes, and thus detachment of catalytic materials is reduced, so that the electrode is excellent in durability such as exhibiting stable performance even in a reverse current flow. Further, since the electrode for electrolysis has a low overvoltage value, an overvoltage required amount of the electrolytic cell can be remarkably reduced. In addition, an electrode for electrolysis having the above effect can be prepared without introducing additional precursors or changing manufacturing facilities.

Electrode for electrolysis and preparation method thereof

A method for preparing a hollow structure, and more particularly, to a method for preparing a hollow structure having various stable structures by using polystyrene particles, into which a functional group is introduced, as a template for preparing the hollow structure.

Method for preparing hollow structure

A catalyst for an oxychlorination process of hydrocarbons, a preparation method thereof, and a method for preparing an oxychlorination compound of hydrocarbons using the same.

Catalyst for processing oxychlorination of hydrocarbon, preparation method therefor, and preparation method of oxychlorinated compound of hydrocarbon using same

A positive electrode active material for a lithium-sulfur battery, and more particularly, to a positive electrode active material for a lithium-sulfur battery including metal sulfide nanoparticles and a preparation method thereof. The metal sulfide nanoparticles with large specific surface area applied to the positive electrode active material for the lithium-sulfur battery according to the present invention acts as a redox mediator during charging and discharging of the lithium-sulfur battery, thereby reducing the shuttle response by not only inhibiting the formation itself of polysulfides with elution properties, but also, even if polysulfides are eluted, adsorbing them and thus preventing them from diffusing into the electrolyte solution, and thus the capacity and life characteristics of the lithium-sulfur battery can be improved.
