微囊藻毒素(Microcystins,简称MCs,目前有100 多种异构体 [1]) 是饮用水源(如湖泊、水库等)的主要污染源之一.MCs 是一种肝脏毒素,具有强促肿瘤和致癌作用.
氢气由于绿色环保、燃烧热值高、可由水制得,被认为能够减轻化石燃料过度使用问题的可再生明星能源之一.我们以石墨相氮化碳(g-C3N4)为基础材料,通过构建多尺度纳米结构、高活性异质结构、以及分子结构调控,发展了新方法合成一系列g-C3N4 基催化剂用于光、电催化分解水制氢,包括零维g-C3N4 量子点、一维g-C3N4 纳米纤维、二维g-C3N4纳米片/纳米网片,三维g-C3N4"海藻",以及氮缺陷
石墨相氮化碳作为典型的非金属2D 层状半导体光催化剂而备受关注.但是,常规热聚合所得体相氮化碳因可见光吸收范围有限和强烈的激子束缚能等缺点,而极大的限制了其光催化活性的提升.
In order to solve mechanics problems,force finding in the problem is an indispensable step.Also,this step is often difficult for not only beginners and also learners who have learned.Therefore,there a
