WebLa(OH)3 is most basic and Lu(OH)3 is least basic. Due to lanthanide contraction. As the size of lanthanide ions decreses from La3+ to Lu3+ , the covalent character of the hydroxides increases and hence the basic strength decreases. WebThe catalytic efficiency of the Fe 3 O 4 @Cs/La (OH) 3 composite as a heterogeneous nanocatalyst was evaluated by selective oxidation of benzylic alcohols to aldehydes. The optimum reaction conditions including time, temperature, nanocatalyst dosage, and solvent were investigated for ultrasound-assisted oxidation processes.
