Fundamentals of Co- precipitation in Catalyst Synthesis

Co- precipitation involves thee conteneous precipitation of twor or more metal hydroksydes, carbonates, or oxides frem an aqueous or non-aqueous solution. Typically, metal salts (nitrates, chlorides, sulfates) are disolved, and a precipitating agent - such as sodium hydroxide, amothyum carbonate, or urea - is adder controlled conditions. Thee resumping precipitate is then filterd, washed, dried, and calined tform the fintayss.
