建构量子力学的精英

物理学史名著《内界》是阿伯拉罕·派斯(Abraham Pais)撰写的一部力作.这部浩瀚的著作写得甚为精彩,其中“量子力学、一份散记”尽管言简意赅,但仍可称为一尊精品,并已得到物理学界广为认肯,特此作一略述,以飨读者.在量子力学建构这一黄金岁月中,海森伯、泡利、狄拉克、约旦等年青精英和薛定谔发挥了主导作用;而他们的老师:玻恩、玻尔、索末菲等也为此作出了各自重要的贡献.     

Graphitic carbon nitride based single-atom photocatalysts

Single-atom photocatalysts, due to their high catalysis activity, selectivity and stability, become a hotspot in the field of photocatalysis. Graphitic carbon nitride (g-C₃N₄) is known as both a good support for single atoms and a star photocatalyst. Developing g-C₃N₄-based single-atom photocatalysts exhibits great potential in improving the photocatalytic performance. In this review, we summarize the recent progress in g-C₃N₄-based single-atom photocatalysts, mainly including preparation strategies, characterizations, and their photocatalytic applications. The significant roles of single atoms and catalysis mechanism in g-C₃N₄-based single-atom photocatalysts are analyzed. At last, the challenges and perspectives for exploring high-efficient g-C₃N₄-based single-atom photocatalysts are presented.
