氧化铝

Some major results are listed as follows. In preparing gold catalysts supported on alumina or ceria and zirconia modified alumina by the direct anion exchange method, it shows considerable simplicity, flexibility and reproducibility. Tuning the gold loadings and washing procedures could control the sizes of gold nanoparticles below 6 nm.
