The preparation of ternary hexagonal boron carbon nitride (h-BCN) nanosheets was carried out by doping biomass glucose in situ into hexagonal boron nitride (h-BN). With this method, the construction of a two-dimensional (2D) semiconductor with tunable bandgap and characteristic adsorption ability toward organic molecules was achieved by maintaining the specific structure of h-BN and π-π interactions toward aromatic compounds. The ternary 2D h-BCN nanosheets worked effectively not only as a desirable adsorbent but also as an activator to benzene. Furthermore, the unique 2D h-BCN nanosheets were found to work as effective photocatalysts to convert benzene into phenol with less over-oxidation, leading to the development of a new type of Fenton oxidation reaction as the one-step visible light-driven hydroxylation of benzene. An optimal yield of 14.0% and its selectivity of 88.3% for the photocatalytic production of phenol from benzene were achieved by using h-BCN in the presence of FeCl₃ and H₂O₂ in sustaining the same reactivity even after 4 cycles. This present study reports the latest development of phenol production from benzene by applying 2D h-BCN nanosheets as an artificial photosynthetic catalyst.

通过将生物质葡萄糖原位掺杂到六方氮化硼（h-BN）中，进行三元六方氮化硼碳氮化物（h-BCN）纳米片的制备。通过这种方法，通过保持h-BN的特定结构和对芳香族化合物的π-π相互作用，可以构建具有可调带隙和对有机分子具有特征吸附能力的二维（2D）半导体。三元2D h-BCN纳米片不仅有效地用作所需的吸附剂，而且还用作苯的活化剂。此外，发现独特的二维h-BCN纳米片可作为有效的光催化剂，以较少的过氧化作用将苯转化为苯酚，从而导致了新型的Fenton氧化反应的开发，该反应是单步可见光驱动的羟基化羟基化反应。苯。最佳产量为14。₃和H ₂ O ₂即使在4个循环后仍保持相同的反应性。本研究报告了通过将二维h-BCN纳米片用作人造光合作用催化剂，从苯生产苯酚的最新进展。
