| 1 | Photocatalysts for Photocatalytic CO_(2)Reduction:A Review显示文摘Energy crisis and environmental pollution have become vitally severe challenges for the current society.During the circumstances of pursuing carbon peak and carbon neutrality,photocatalytic CO_(2) reduction will be an essential,necessary and even inevitable development requirement and trend.However,there are some bottlenecks that need to be addressed immediately,such as low quantum efficiency and narrow light absorption range for single photocatalysts.Therefore,efficient and stable visible light driving materials are the core challenge in the field of photocatalytic CO_(2) conversion.This paper reviewed the photocatalysts used for CO_(2) reduction classified as metal photocatalysts,non-metal photocatalysts,and MOFs photocatalysts,and the CO_(2) reduction capacity and mechanism of different photocatalysts were described.In the end,the problems to be solved and the future development of photocatalytic CO_(2) reduction were summarized. | Zhang Lizhong | 2022 | China Petroleum Processing & Petrochemical Technology2022,24,1: | 2 |
| 2 | 大比表面积催化材料制备方法研究进展显示文摘通过增加材料表面区域,可以促进活性组分高度分散,加速催化剂的电子迁移并改变材料表面酸性位,极大地提高催化活性。因此,大比表面积催化材料的制备已经成为研究的热点。尽管诸多研究都已经注意到了材料比表面积变化对于催化性能的重要性,但是目前的研究系统性仍有不足,亟待揭示比表面积和催化之间的构效关系,探明大比表面积材料的结构演化机制和对性能的影响机理,构筑影响催化活性的关键结构特性,实现催化材料的可控制备。本综述系统总结了大比表面积催化材料的不同制备方法、物理化学机理、特性分析、制备面临的挑战,并对未来发展进行了展望。重点阐述了材料的形貌特性、尺度特性和元素特性对大比表面积催化材料制备的影响和限制。 | 亓占丰 赵心舒 王珍 郭秀丽 | 2022 | 稀有金属材料与工程2022,51,5: | 1 |
| 3 | BiVO_(4)/C_(3)N_(4)异质结界面电荷传输机制调控显示文摘直接Z型异质结是理想的全解水光催化剂形式之一.C_(3)N_(4)的价带电位约为+1.6 V(vs.NHE,pH 0),在热力学上限制了其产氧性能.C_(3)N_(4)与具有较强氧化电势的半导体复合构建Z型异质结,有利于提高光催化效率.构建直接Z型的关键在于对界面电荷传输路径的精确控制.通过调控半导体的氧缺陷浓度可有效改变其功函数,进而改变异质结界面处的能带弯曲方向以选择性控制光生载流子的传递路径.利用水热法合成BiVO4并降低氧缺陷含量,从而使其功函数逐渐增大.当氧缺陷含量较高时,BiVO_(4)的功函数小于C_(3)N_(4);而当氧缺陷含量较低时,其功函数大于C_(3)N_(4).这种功函数相对值的变化进一步改变了异质结界面处的能带弯曲方向,进而使BiVO_(4)/C_(3)N_(4)由Ⅱ型转变为Z型.与Ⅱ型异质结不同,直接Z型BiVO_(4)/C_(3)N_(4)实现了高效的光催化全解水,且420 nm处的表观量子效率为4.4%. | 孙尚聪 高睿杰 刘显龙 潘伦 史成香 姜政 张香文 邹吉军 | 2022 | Science Bulletin2022,67,4: | 0 |
