In today's increasingly global consensus on environmental protection, silica has become an important role in the green revolution due to its environmentally friendly and renewable characteristics. As a widely present compound in nature, the preparation process of silica is relatively simple and does not cause serious environmental pollution. In the field of environmentally friendly materials, silica is widely used in water treatment, air
purification, soil remediation, and other areas. For example, silica based adsorbent materials can effectively remove heavy metal ions and organic pollutants from water, ensuring the safety of drinking water. Meanwhile, silica based catalysts exhibit efficient and stable performance in exhaust gas treatment, which helps reduce industrial emissions and environmental pollution. In addition, silica is also an ideal soil amendment that can improve soil structure and enhance soil fertility. On the path of green development, silica is writing its own chapter with its unique environmental advantages.
