Abstract

This study presents an innovative application of solid-state photocatalysis using environmentally friendly TiO₂/biochar composites to degrade polypropylene (PP) films and reduce plastic pollution. Biochar, derived from coconut shells via controlled pyrolysis, was combined with TiO₂ to enhance photocatalytic activity. A 416B-type Central-Hybrid Experimental Design was used to optimize synthesis parameters, revealing that biochar produced at 280°C with 4.1 % v/v oxygen and a TiO₂/biochar weight ratio of 1.5 yields the best results. After 25 days of UV irradiation, films incorporated with TiO₂/biochar composites exhibited an 8.7 % weight loss and a carbonyl index of 11.4—significantly surpassing pristine PP films. These findings demonstrate the potential of biochar as a sustainable solution to reduce nanotoxicity while boosting polymer degradation efficiency. This work contributes to the development of eco-friendly materials for mitigating plastic waste challenges.

采用416b型中心杂化实验设计，评价TiO2/生物炭复合材料对聚丙烯塑料薄膜的固态光催化降解的合成条件

本研究提出了一种利用环境友好型TiO2/生物炭复合材料进行固态光催化降解聚丙烯（PP）薄膜并减少塑料污染的创新应用。通过控制热解从椰子壳中提取生物炭，并与TiO2结合以增强光催化活性。采用416b型中心杂化实验设计对合成参数进行优化，结果表明，在280℃、4.1 % v/v氧气条件下，TiO2/生物炭质量比为1.5时制备的生物炭效果最佳。经过25天的紫外线照射后，TiO2/生物炭复合材料的膜质量下降了8.7% %，羰基指数为11.4，显著超过了原始PP膜。这些发现证明了生物炭作为一种可持续的解决方案的潜力，可以降低纳米毒性，同时提高聚合物的降解效率。这项工作有助于开发环保材料，以减轻塑料废物的挑战。
