Au _0.3 Pd _0.7 /A-M-β-CD exhibits remarkable catalytic activity for hydrogen evolution from formic acid, which is attributed to strong metal–support interaction.

Fe-based amorphous alloys have shown great potential in degrading azo dyes and other organic pollutants. It has been widely investigated as a kind of environmentally friendly material for wastewater remediation. In this paper, we studied the effect of Ni addition on the catalytic performance of Fe₈₇Si₅B₂P₃Nb₂Cu₁ amorphous alloy for degradation of methylene blue dyes and analyzed the reaction mechanism. (Fe₈₇Si₅B₂P₃Nb₂Cu₁)₈₆Ni₁₄ amorphous powder with desirable performance was produced by specific ball milling durations. Characterization of the Fe₈₇Si₅B₂P₃Nb₂Cu₁ and (Fe₈₇Si₅B₂P₃Nb₂Cu₁)₈₆Ni₁₄ amorphous alloys prepared by ball milling was performed by XRD and SEM. Fe₈₇Si₅B₂P₃Nb₂Cu₁ and (Fe₈₇Si₅B₂P₃Nb₂Cu₁)₈₆Ni₁₄ amorphous alloys were used as catalysts to catalyze the degradation of methylene blue dyes, which were detected by UV-VIS near-infrared spectrophotometer. By a series of comparative experiments, it was found that a catalyst dosage of 0.2 g and a reaction temperature of 80 °C were conditions that produced the best catalytic effect. The degradation rate of (Fe₈₇Si₅B₂P₃Nb₂Cu₁)₈₆Ni₁₄ amorphous alloy to methylene blue dyes prepared by ball milling increased from 67.76% to 99.99% compared with the Fe₈₇Si₅B₂P₃Nb₂Cu₁ amorphous alloy under the same conditions.
