Graphitic carbon nitride (g-CN) is a promising candidate for photocatalysis, but exhibits moderate activity due to strongly bound excitons and sluggish charge migration. The dissociation of excitons to free electrons and holes is considered an effective strategy to enhance photocatalytic activity. Herein, a novel boron nitride quantum dots (BNQDs) modified P-doped g-CN photocatalyst (BQPN) was successfully prepared by thermal polymerization method. Read More

Photocatalysis is facing huge challenges especially the separation and efficient utilization of photocarriers. Herein, we report that a ternary hollow core-shell photocatalyst is synthesized by template and self-assembled method. The experimental results show that the electron separation efficiency and utilization efficiency are significantly improved, not only because the ternary hollow core-shell structure spatially separates the oxidation area MnOx from the reduction area Co-MOF, but also because lots of emergent electrons are stored in Co-MOF as an electronic library, contributing to the formation of surface polarization to support the requirement call from the CoP quantum dots (QDs) as active-sites.

We report a unique photoanode architecture involving TiO, g-CN, and AuNPs wherein a synergistic enhancement of the photoelectrochemical (PEC) performance was obtained with photocurrent densities as high as 3 mA cm under AM1.5G 1 sun illumination. The PEC performance was highly stable and reproducible, and a photoresponse was obtained down to a photon energy of 2. Read More

Efficient and nondestructive liquid exfoliation of MXene with large lateral size has drawn growing research interest due to its outstanding properties and diverse potential applications. The conventional sonication method, though enabling a high production yield of MXene nanosheets, broke them down into submicrometric sizes or even quantum dots, and thus sacrificed their size-dependent properties, chemical stability, and wide applications. Herein, rigid biological nanofibrils in combination of mild manual shake were found to be capable of peeling off MXene nanosheets by attaching on MXene surfaces and localizing the shear force.
