Tungsten hexacarbonyl (also called tungsten carbonyl) is the chemical compound with the formula W(CO)₆. This complex gave rise to the first example of a dihydrogen complex. This colorless compound, like its chromium and molybdenum analogs, is noteworthy as a volatile, air-stable derivative of tungsten in its zero oxidation state.
High-entropy nano-array for electrocatalytic reduction of nitrate coupled with waste plastic conversion and preparation method thereof
A high-entropy nano-array for electrocatalytic nitrate reduction coupling waste plastic conversion is prepared by the following method: (1) immerse the nickel foam into a hydrochloric acid solution to remove the surface oxide layer and oil stains, rinse with deionized water / ethanol three times, and dry for subsequent use; (2) solid powders of sodium chloropalladate, platinum acetylacetate, nickel chloride hexahydrate, copper chloride dihydrate, silver trifluoroacetate and tungsten hexacarbonyl are poured into an N-N dimethylformamide solution, ultrasonic is used to dissolve the solid powders, then glacial acetic acid and the treated nickel foam are added to the above solution, and after ultrasonic, heating in an oven is carried out, after the reaction is completed, water and ethanol solution are used for alternate washing, and drying is carried out, and the high-entropy nano-array catalyst is obtained. A preparation method of a high-entropy nano-array for electrocatalytic nitrate reduction coupling waste plastic conversion is provided. The high-entropy nano-array has excellent electrocatalytic activity and stability.
