Nanoscale boron carbonitride semiconductors for photoredox catalysis
The conversion of solar energy to chemical energy has received significant attention in recent years, achieved by photocatalysis comprising homogeneous transition-metalbased systems, organic dyes, or semiconductors. Among those photocatalysts, boron carbon nitride (BCN) materials, as an emerging class of metal-free heterogeneous semiconductors, have extended the field of photocatalysts due to good performance and earth-abundant constitute. The combination of boron (B), carbon (C), and nitrogen (N) constitutes a ternary system with the large extent, large surface area, and abudant activity sites, which together contributed to good performance for reduction reactions, oxidation reactions and orchestrated both reduction and oxidation reactions. This Minireview concludes the methods to the synthesis of nanoscale hexagonal boron carbonitride (h-BCN) and describes the latest advances in applying h-BCN as semiconductor photocatalysts for sustainable photosynthesis, such as water splitting, reduction of CO2, acceptorless dehydrogenation, oxidation of sp3 C-H bonds, and sp2 C-H functionalization. The h-BCN materials would have a potential application in other organic transformations and industrial manufacture in the future.
