This study presents the generation of a renewable fuel using acetic acid as electron donor, copper slag (CS) as photocatalyst and UV–Vis irradiation. The CS was characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), and UV–Vis spectroscopy. Specific surface area (S_BET) was determined on basis of N₂ isotherms. A 2³ factorial experimental design was performed to identify factors controlling the hydrogen evolution and mineralisation of acetic acid. The experimental factors were: slag dose (0.1, 0.55 and 1 g/L), acetic acid concentration (1, 5.5 and 10% vol) and reaction time (2, 5 and 8 h). Synthetic acetic acid solutions were used. An Analysis of Variance (ANOVA) was performed showing that slag dose, reaction time and an interaction between both factors were statistically significant (p-value < 0.05) for hydrogen generation. Two absorption edges (2.2 and 2.6 eV) were determined associated with the presence of fayalite and magnesioferrite identified by XRD. The best rate of the hydrogen production was 4.35 μmol/h g CS at 10% vol acetic acid, 0.1 g/L of CS and 2 h of reaction. This value is similar to values reported using similar catalysts. CS performance is due to the high iron content (60.09% wt. as Fe₂O₃) and traces of other semiconductors such as zinc, copper and manganese which may have some contribution to the photocatalytic activity.

这项研究介绍了使用乙酸作为电子供体，使用铜渣（CS）作为光催化剂和使用UV-Vis辐射生成可再生燃料的方法。CS的特征在于X射线衍射（XRD），X射线荧光（XRF），扫描电子显微镜（SEM）和UV-Vis光谱。基于N ₂等温线确定比表面积（S _BET）。2 ³进行析因实验设计，以识别控制氢的释放和乙酸矿化的因素。实验因素是：渣量（0.1、0.55和1 g / L），乙酸浓度（1、5.5和10％vol）和反应时间（2、5和8 h）。使用合成乙酸溶液。进行方差分析（ANOVA）表明，炉渣剂量，反应时间以及两个因素之间的相互作用对于制氢均具有统计学意义（p值<0.05）。确定了两个吸收边缘（2.2和2.6 eV），与通过XRD鉴定的铁橄榄石和镁铁矿有关。在10％体积乙酸，0.1 g / L CS和2 h反应的条件下，最佳产氢速率为4.35μmol/ h g CS。该值类似于使用类似催化剂报道的值。₂ O ₃）和其他可能对光催化活性有贡献的其他半导体（如锌，铜和锰）的痕迹。
