In this study, a comprehensive systematic review was conducted to better recognize the applicability of graphene-based photocatalytic processes for the degradation of tetracycline (TC) from water. A broad search strategy was developed for English language articles available in PubMed, Scopus, and Web of Science. The effect of parameters such as pH, TC concentration, photocatalyst dose, radiation source intensity, and the effect of graphene on the process, kinetics, and reuse of the photocatalyst were investigated. A total of 63 out of a possible 3498 retrieved records met inclusion criteria. The results showed that most related studies have increased since 2019. About 46.7% of the articles showed 90-100% TC removal efficiency and 59.52% of the studies had optimal pH equal to 5 and 6. Also, the widespread use of visible light had a significant trend. The effect of the dose of graphene in the catalyst was one of the most important and effective factors on the process; hence, the difference in efficiency with and without graphene was completely evident. This review indicated that the presence of graphene has been able to have a positive effect on increasing the efficiency of oxidation processes, and it can be used for environmental pollutants remediation.
在这项研究中，进行了全面的系统综述，以更好地认识基于石墨烯的光催化过程在水中降解四环素（TC）的适用性。制定了一个广泛的搜索策略，以检索 PubMed、Scopus 和 Web of Science 中可用的英文文章。研究了 pH 值、TC 浓度、光催化剂剂量、辐射源强度以及石墨烯对过程、动力学和光催化剂再利用的影响等参数的影响。在总共 3498 条可能检索到的记录中，有 63 条符合纳入标准。结果表明，自 2019 年以来，大多数相关研究的数量有所增加。约 46.7%的文章显示 90-100%的 TC 去除效率，59.52%的研究最佳 pH 值等于 5 和 6。此外，可见光的广泛使用呈现出显著的趋势。催化剂中石墨烯剂量的影响是该过程最重要和最有效的因素之一；因此，有和没有石墨烯的效率差异非常明显。本综述表明，石墨烯的存在能够对氧化过程的效率产生积极影响，可用于环境污染物的修复。
