“…During the ball‐milling treatment of graphite, the particle size of ball‐milled graphite will suffer from decrease and more edges/defects are exposed, which is beneficial to the catalytic activity optimizing . With respect to the ball‐milling treated BiPO 4 , Zhu et al found that numerous defects of BiPO 4 such as Bi vacancies, O vacancies were formed during the ball‐milling process . However, since the formed defects were bulk defects, which inhibited the separation of photogenerated charges, thus reduced the photocatalytic activity.…”

2D Nanomaterials, with unique structural and electronic features, have shown enormous potential toward photocatalysis fields. However, the photocatalytic behavior of pristine 2D photocatalysts are still unsatisfactory, and far below the requirements of practical applications. In this regard, surface defect engineering can serve as an effective means to tune photoelectric parameters of 2D photocatalysts through tailoring the local surface microstructure, electronic structure, and carrier concentration. In this review, recent progress in the design of surface defects with the classified anion vacancy, cation vacancy, vacancy associates, pits, distortions, and disorder on 2D photocatalysts to boost the photocatalytic performance is summarized. The strategies for controlling defects formation and technique to distinguish various surface defects are presented. The crucial roles of surface defects for photocatalysis performance optimization are proposed and advancement of defective 2D photocatalysts toward versatile applications such as water oxidation, hydrogen production, CO 2 reduction, nitrogen fixation, organic synthesis, and pollutants removal are discussed. Surface defect modulated 2D photocatalysts thus represent a powerful configuration for further development toward photocatalysis.

Phosphorus compounds, such as metal phosphides and phosphates have shown excellent performances and great potential in electrochemical energy storage, which are demonstrated by research works published in recent years. Some of these metal phosphides and phosphates and their hybrids compare favorably with transition metal oxides/hydroxides, which have been studied extensively as a class of electrode materials for supercapacitor applications, where they have limitations in terms of electrical and ion conductivity and device stability. To be specific, metal phosphides have both metalloid characteristics and good electric conductivity. For metal phosphates, the open-framework structures with large channels and cavities endow them with good ion conductivity and charge storage capacity. In this review, we present the recent progress on metal phosphides and phosphates, by focusing on their advantages/disadvantages and potential applications as a new class of electrode materials in supercapacitors. The synthesis methods to prepare these metal phosphides/phosphates are looked into, together with the scientific insights involved, as they strongly affect the electrochemical energy storage performance. Particular attentions are paid to those hybrid-type materials, where strong synergistic effects exist. In the summary, the future perspectives and challenges for the metal phosphides, phosphates and hybrid-types are proposed and discussed.

“…[41] As g-C3N4 transforms from nano-plates to nano-rods, the improvements of photo-catalysis and photocurrent intensity in g-C3N4 nano-rods probably resulted from the increase of active lattice face and decrease of surface defects. [41,140] Substrate-assisted hydrothermal method is also an interesting idea to fabricate g-C3N4 nano-ribbons. Zhao et al reported a 3D assembly architecture of 1D g-C3N4 nano-ribbons with 2D graphene sheets via a one-step hydrothermal method.…”
