Precious metal nanometric catalysts are widely used in the removal of harmful substances. In the process of synthesis và catalytic reaction, it is particularly important khổng lồ study green và simple synthesis methods and high catalytic efficiency. In this paper, a green one-step method was used lớn synthesize the Fe(OH)3/Fe2O3
Au composite catalyst, in which Au was single atom-dispersed. The removal of 4-nitrophenol (4-NP), a typical dangerous chemical widely existing in factory waste gas, waste water and automobile exhaust gas, was catalysed by Fe(OH)3/Fe2O3
Au with different synthesis conditions (different amounts of MES, NaBH4, FeSO4, Au và Pt) on the 4-NP reduction reaction were systematically studied. Finally, the stability và recyclability of Fe(OH)3/Fe2O3
