To achieve a ZrO2-B-C ternary solid-state reaction, a small amount of carbon was introduced into a binary system of ZrO2 and boron. Amorphous hydrous ZrO2 precursor was firstly prepared through precipitation method using zirconyl nitrate and ammonia at room temperature. Then, ZrB2 powder was successfully synthesized using the as-prepared amorphous hydrous nano-ZrO2 via borothermal and carbothermal...
In this study, CeO2 and a mixture of TiO2 and CeO2 (CeO2-TiO2, Ce: Ti (mol.) = 3: 1) were synthesized by the solvothermal method at different temperatures. The particle size, either CeO2 or CeO2-TiO2 synthesized at 140 °C was less than 10 nm. Nitrogen and carbon co-doped CeO2 was synthesized using hexamethylenetetramine (HMT) as a precipitator at 140 °C. The degradation ratio of acid orange 7 (AO7)...
