酒，乃天地之精华，文化之载体，品一杯佳酿，如同品一段历史，品一份人生。白酒在各种场合中发挥着重要作用，它不仅仅是一种饮品，还寄托着人们对美好生活的向往和追求。本文采用生动形象的对话形式，通俗易懂地描述了白酒酿制的五个主要过程——选料、糖化、发酵、蒸馏和陈酿，重点介绍了其中的主要化学成分以及酿制过程中的化学反应，白酒的酿造过程体现了匠心独运的精神以及酒文化的博大精深。通过品味白酒，可以更好地感悟人生的哲理和智慧。好酒需要陈放才能更加醇香，人生也需要经历岁月的沉淀才能更加丰富多彩。

A simple two-step hydrothermal method synthesized four different CdS/Fe₃O₄ photocatalysts with varying ratios of mass of CdS to Fe₃O₄. The composition and morphology of the prepared samples were investigated using X-ray diffraction (XRD), Raman spectrum, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Solid UV reflectance spectra testing found that CdS/Fe₃O₄ nanocomposites had good light absorption throughout the spectral range, promoting their photocatalytic properties. Under visible light irradiation, CdS/Fe₃O₄ (2:5) with a mass ratio of 2:5 exhibited excellent photocatalytic performance, with a degradation rate of 98.8% for rhodamine B. Furthermore, after five cycles of photocatalytic degradation reaction, the rhodamine B degradation rate remained at 96.2%, indicating that the photocatalysts have good photocatalytic stability.
