Waste valorization for the production of valuable materials is of great importance for sustainable development. Herein, a new green methodology for the synthesis of photocatalytically active copper sulfide (Cu₂S) carbon composites using pig bristles is reported. The catalyst was prepared via microwave-assisted methodology using ethylene glycol as the solvent, pig bristles as the sulfur and carbon source, and copper chloride as the metal precursor. Cu₂S carbon composites (denoted as pb-Cu₂S, where “pb” stands for “pig bristle”) were characterized by XRD, N₂ physisorption, EDX and UV-Vis spectroscopy. In order to validate the practical utilization of pig bristle-derived chemicals, the photocatalytic degradation of methyl red using pb-Cu₂S was investigated under white, blue, green and red visible light irradiation.

微波辅助猪鬃的增值：对可见光光催化辉石复合材料的研究

为生产有价值的材料而进行的废物增值对可持续发展非常重要。在本文中，报道了使用猪鬃合成光催化活性硫化铜（Cu ₂ S）碳复合材料的一种新的绿色方法。通过微波辅助方法，以乙二醇为溶剂，猪鬃为硫和碳源，氯化铜为金属前体，制备催化剂。用XRD，N ₂表征了Cu ₂ S碳复合材料（表示为pb-Cu ₂ S，其中“ pb”代表“猪鬃”）。物理吸附，EDX和UV-Vis光谱。为了验证猪鬃化学药品的实际应用，在白色，蓝色，绿色和红色可见光照射下，研究了使用pb-Cu ₂ S对甲基红的光催化降解。
