Abstract

The photoreforming of polyethylene terephthalate and bisphenol A was here investigated using uncommon photocatalysts (SiC-g-C₃N₄ composites). The results showed as the addition of small amounts of g-C₃N₄ on SiC promoted an efficient charge carriers separation and a good interaction between the two materials, leading to a H₂ production rate of 18 and 12 μmolH₂/g_cat∙h for the photoreforming of polyethylene terephthalate and bisphenol A, respectively. The accurate selection of different g-C₃N₄ precursors, combined with the appropriate control of the key reaction parameters (pH and plastic materials pretreatments) allowed to optimize the performance of the SiC-g-C₃N₄ composites for the photocatalytic H₂ production.

利用 SiC-g-C3N4 复合材料对塑料材料进行太阳能光致转化生产 H2

本文使用不常见的光催化剂（SiC-g-C3N4 复合材料）研究了聚对苯二甲酸乙二醇酯和双酚 A 的光转化。结果表明，在 SiC 上添加少量 g-C3N4 可促进电荷载流子的有效分离以及两种材料之间的良好相互作用，从而使聚对苯二甲酸乙二醇酯和双酚 A 的光致转化率分别达到 18 μmolH2/gcat∙h 和 12 μmolH2/gcat∙h。准确选择不同的 g-C3N4 前体，结合适当控制关键反应参数（pH 值和塑料材料预处理），可以优化 SiC-g-C3N4 复合材料光催化产生 H2 的性能。
