| use | (1)Rh(acac)3 and hydroxypyridine catalyzed CO/H2 synthesis of ethylene glycol; Rh(acac)3 catalyzed selective reduction of dicarboxylic acid monoester; Using Rh(acac)3/THF system to prepare ultra-porous rhodium membrane catalyst on silicon. (2) Using Pd(acac)2 and Rh(acac)3 as precursors, metal and alloy coatings and films were prepared by CVD technology. (3) Used as a homogeneous catalyst for hydrosilylation reaction, asymmetric redox reaction, etc. (4) Preparation of Lao carrier catalyst. (5) Preparation of nanoparticles or nano-alloy particles, metal colloids and nano-metal carrier catalysts. MOCVD precursor compound, homogeneous catalyst, precursor compound for preparing supported catalyst |
| production method | mixing rhodium nitrate (iii) aqueous solution containing 0.1g rhodium and 10mL 0.2mol/L nitric acid, and adjusting the pH value to 4 with 10% sodium bicarbonate aqueous solution. At this pH, the light yellow hydroxide (or basic nitrate) begins to precipitate. Add 5mL of acetylacetone and heat to reflux the reaction mixture. After a few minutes, orange-yellow crystals began to precipitate, and the pH value of the mixed solution also decreased. After 30min, adjust the pH value to 4 and continue to reflux for 15min. Then cool to room temperature, filter out the precipitated crystals and dry them. Recrystallization with water and methanol mixed solvent to obtain 0.3g of rhodium acetylacetonate with 75% yield. |
