Two-dimensional H– and F–BX (X = O, S, Se, and Te) photocatalysts with ultrawide bandgap and enhanced photocatalytic performance for water splitting

Abstract

We theoretically propose a type of monolayer structure, H– or F–BX (X = As, Sb; Y = P, As), produced by surface hydrogenation or fluorination, with high stability, large band structures and high light absorption for photocatalytic water splitting.

In situ synthesis of g-C3N4/Ti3C2Tx nano-heterostructures for enhanced photocatalytic H2 generation via water splitting

“…Hence, the nano-heterostructure of Ti 3 C 2 T x and g-C 3 N 4 can efficiently separate and transport the photo-induced electrons and holes, significantly improving the performance of the photocatalytic system. 85,86 This enhanced activity was observed for gCN-0.75, given that this was the optimal combination of g-C 3 N 4 and Ti 3 C 2 T x for the formation of the coupled catalyst system among the prepared compositions, as discussed in the previous section. 76 Furthermore, the stability and reusability of the catalyst were assessed using a recycling study of the most active sample for 3 cycles, i.e.…”

Magnetic Composite Lignin Colloids Prepared with a Convenient Patching Method for Generally Treating Heterogeneous Oily Wastewater

“…IPTS was used to modify the surface of Fe 3 O 4 @SiO 2 nanoparticles to obtain isocyanate active sites on the surface of composite particles (Figure 2c). [ 25 ] Abundant N on the surface of Fe 3 O 4 @SiO 2 ‐NCO particles can be clearly detected by EDX characterization (Figure 2d). Fortunately, the particle size of the modified lignin hardly changed, but it still maintained good dispersion in THF solvent (Figure S3a, Supporting Information), which provided an important advantage for subsequent lignin grafting.…”

Crystal Engineering and Self‐Assembled Nanoring Formation with Purine‐CdII/HgII Supramolecular Frameworks

“…have been explored. Biological scaffolds like proteins, [28] peptides [29–31] enzymes [32] and purines [33–35] have been employed for the same. Purine systems including natural nucleobases, their derivatives and metal coordination frameworks have successfully yielded useful nanoarchitectures.…”
